The solution homework 3.3 M101JS: MongoDB for Node.js Developers
Making your blog accept comments
In this homework, you will add code to your blog so that it accepts comments. Download and unpack the files for this homework from the Download Handout link. You will be using the same code as you downloaded for homework 3.2, along with the changes you made.
We have removed parts of the code that uses the Node.js driver to query MongoDB from posts.js and marked the area where you need to work for HW 3.3 with “hw3.3 TODO”.
In a terminal:
Linux/Mac:
cd blog/
grep -rn "hw3.3 TODO" *
Windows:
cd blog/
find /n "hw3.3 TODO" *
You should not need to touch any other code. The database call that you are going to add will add a new comment to a given post.
This assignment has fairly little code, but it’s a little more subtle than the previous assignment because you are going to be manipulating an array within the Mongo document. For the sake of clarity, here is a document out of the posts collection from a working project that also has comments.
{
"_id" : ObjectId("513d396da0ee6e58987bae74"),
"author" : "andrew",
"body" : "Representatives from the planet Mars announced today that the planet would adopt MongoDB as a planetary standard. Head Martian Flipblip said that MongoDB was the perfect tool to store the diversity of life that exists on Mars.",

{
"author" : "Larry Ellison",
"body" : "While I am deeply disappointed that Mars won't be standardizing on a relational database, I understand their desire to adopt a more modern technology for the red planet.",
"email" : "larry@oracle.com"
},
{
"author" : "Salvatore Sanfilippo",
"body" : "This make no sense to me. Redis would have worked fine."
}

}
As a reminder, to run your blog, go into the blog directory and type:
npm install
node app.js
Note that you add comments in this blog from the blog post detail page, which appears at
http://localhost:8082/post/post_slug
where post_slug is the permalink. For the sake of eliminating doubt, the permalink for the example blog post above is
Ok, now it’s time to validate you got it all working.
From the top of this page, there was one additional program that should have been downloaded:mongoProc.
With it, you can test your code and look at the Feedback section. When it says “user creation successful” and “user login successful”, you can Turn in your assignment.
Solution:
Open blog/user.js and paste following codes or make changes near hw3.3
/* The PostsDAO must be constructed with a connected database object */
function PostsDAO(db) {
"use strict";
/* If this constructor is called without the "new" operator, "this" points
* to the global object. Log a warning and call it correctly. */
if (false === (this instanceof PostsDAO)) {
console.log('Warning: PostsDAO constructor called without "new" operator');
return new PostsDAO(db);
}
var posts = db.collection("posts");
this.insertEntry = function (title, body, tags, author, callback) {
"use strict";
console.log("inserting blog entry" + title + body);
// fix up the permalink to not include whitespace
var permalink = title.replace( /\s/g, '_' );
permalink = permalink.replace( /\W/g, '' );
// Build a new post
var post = {"title": title,
"author": author,
"body": body,
"permalink":permalink,
"tags": tags,
"comments": [],
"date": new Date()}
// now insert the post
// hw3.2 TODO
//Solution:

In this homework, you will be enhancing the blog project to insert entries into the posts collection. After this, the blog will have basic functionality. It will allow you to add blog posts with a title, body, and tags and have it be added to the posts collection properly.
We have provided the code that creates users and allows you to log in (the assignment from last week). Download and unpack the files for this homework from the Download Handout link.
We have removed parts of the code that uses the Node.js driver to query MongoDB from posts.js and marked the area where you need to work for hw3.2 with “hw3.2 TODO”.
In a terminal:
Linux/Mac:
cd blog/
grep -rn "hw3.2 TODO" *
Windows:
cd blog/
find /n "hw3.2 TODO" *
You should not need to touch any other code. The database call that you are going to add will insert a new post into the posts collection. Here is an example of a valid blog post:
> db.posts.find().pretty()
{
"_id" : ObjectId("513d396da0ee6e58987bae74"),
"title" : "Martians to use MongoDB",
"author" : "andrew",
"body" : "Representatives from the planet Mars announced today that the planet would adopt MongoDB as a planetary standard. Head Martian Flipblip said that MongoDB was the perfect tool to store the diversity of life that exists on Mars.",
"permalink" : "martians_to_use_mongodb",
"tags" : [
"martians",
"seti",
"nosql",
"worlddomination"
],
"comments" : [ ],
"date" : ISODate("2013-03-11T01:54:53.692Z")
}
As a reminder, to run your blog, go into the blog directory and type:
npm install
node app.js
To play with the blog you can navigate to the following URLs:

In this internship final report sample, we are showing you the full report, with a background of the study, objectives of the study, Limitations of the Study, Selection Method of Data Collection and the whole report body.
CHAPTER 1
Introduction
1.1 Background of the study
The internship program has become the bridge for those who want to enter to corporate level from the college life, through an internship I got to know the real working environment which was very much different from my course study.
The internship has developed a kind of confidence in me that now I can do something different from new employees and I can work as an employee. The main things I learned from the internship are the value of time and the importance of punctuality and rules and regulations that we have to follow as an employee.
1.2 Objectives of the study
The general objective of this report is to partially fulfill the requirements for the degree of BCIS. However, the specific objectives are as follows:
To find the use of Websites in today’s society.
To develop the Management Skills, Personality, and Teamwork.
To develop interpersonal skills, conceptual as well as technical skills.
Tips and techniques to design and program websites.
The technique to earn online.
1.4 Limitations of the Study:
Major limitations of internship report are as follows:
Lack of proper research and detailed information about the company and its operating activities.
The time frame to perform an internship was short.
Lack of knowledge to run programs and software used by DP Sign.
Object-oriented based programming and use of different programming languages in DP Sign stopped me to learn more.
1.5 Selection Method of Data Collection
There are two major approaches to gathering information in my internship about the situation, person, problems or phenomenon and software in DP Sign.
Internal information
External Information
This information was collected with the help of both primary and secondary resources.
Primary Data: They are collected by me on the concerned topic, which is original. While studying I have come across sources such as direct interviews with the supervisor, opinion of the different employees, informal talks with the employees, etc.
Secondary Data: They are collected by me on the basis of the study of networking in organizations. For preparing this report on networking and data communication I have collected information through Nepal Bank, internet, books, teachers, and some previous records.

2.3 Mission Statement of the company
“Our mission is to offer advanced, convenient, and money-saving digitally printing things in Monitors or papers with the implementation of distinctive ideas and expertise. Our foundation of survival is based on providing valued clients a convenient and affordable source for digitalizing the world“.
In a clear sense, our motto is to be “A strategic partner of our clients, not a mere vendor.”
2.4 D.P. Sign’s spirit is infused into every component
D.P. Sign doesn’t simply just make and sell products; we are also deeply concerned with a number of issues, such as quality products, quick service, after-sale services and what type of services would be ideal for the clients.

The categories below summarize our most common tasks.
2.5.2 Web-based application design and development
Business workflow management
CRM
MIS
2.5.3 Generic/custom software solutions (in different platforms/domains)
Auto
Pharmaceuticals
Mortgage
2.5.4 Embedded software solutions
2.5.5 Online Earning Training
2.6 Engagement Models
2.6.1. Fixed price turnkey model
This model is applicable for projects where requirement specifications and timelines are clearly defined and frozen. This helps clients if they have a fixed budget for development and are clear about their requirements. We work with our client to define expected deliverables to determine a mutually agreed fixed price.
2.6.2. Per resource model
This model offers clients the flexibility to alter requirement specification, team size and timeline of projects based on market trends and feedback. This model suits best for most of the projects due to a software development project’s inherent need for altering specifications throughout the development life cycle. The client pays a monthly fee per resource (development, QA or management).
2.6.3. Offshore model
Our core expertise lies in establishing Offshore Development Centers for its clients. Through this model we serve our clients with highly experienced professionals with varied skill sets, resources, flexibility and time & cost‐to‐market advantages, allowing them to enjoy the long term gains of offshore outsourcing. DP SIGN operates as an extension to clients’ existing software engineering business. The secret of its success can be attributed to the fact that this model gives an opportunity to the client to make direct communication with DP SIGN through the onsite center and at the same time gives them the chance of enjoying the benefits of offshore development. Round the clock development is seamlessly done with this model. In this model, the client pays an offshore center on a per month basis.
2.7 Delivery Model
A proper combination of synthesis motivates every engagement, enabling us to deliver technology solutions that give our clients a decisive competitive advantage. The client can decide among one of the following delivery models
Full offshore development
Full Onsite development with our developers and QA resource deployed at the client’s site
Hybrid model when the majority of the team is offshore and the few members are onsite to help gather business requirements and help in deliverables.
Above mentioned models cater to the different requirements of clients like augmenting their development or QA teams, forming a new and complete project team, getting architects and designers for new technology development. However, more onsite involvement increases the total cost of development. DP SIGN management team works with the client to help them choose the best model that fits into their business requirements.
2.8 Process and Standards
The following standards summarize the commitment of DP SIGN towards the international best practices.
2.8.1 Project management standards
At DP SIGN, we believe that project management is the key to the success of any project, more so for IT projects. We closely follow the PMBOK as set by the Project Management Institute (PMI) standards.
2.8.2 CMMI: The process improvement initiatives
We have initiated the development of process standards in‐house with the implementation of CMMI (Capability Maturity Model Integration). This process improvement approach will provide our organization with the essential elements of effective processes. CMMI can be used to:
guide process improvement across a project or throughout an entire organization
integrate traditionally separate organizational functions
set process improvement priorities and goals
Processes being the pivot of the realization of products/services, DP SIGN ensures that every pertinent activity comports with the defined processes. The following sequence features the processes that are executed during the entire development lifecycle

Web site development in DP Sign is done in two ways, either it is built in-house or it is bought.
2.14.2.1 In-House Development
2.14.2.1.1 Design the application architecture
Application architecture defines the technologies to be used by one or more or all information systems in terms of their data, processes, interfaces and network components. In DP Sign database like MySQL, SQL, Oracle, MySQL, etc were in use, I use MySQL. They use .net and PHP as the programming language and I prefer to use PHP language in website programming.
The physical data flow diagram is used to establish physical processes and location issues.
2.14.2.1.2 Design the database(s)
The purpose of this task is to prepare technical design specifications for a database that will be adaptable to future requirements and expansion. System analyst also participates in the database modeling and the system designers are responsible for the completion of the activity as databases are shared resource.
The database schema is also structured.
2.14.2.1.3 Design the system interface
In this, the system designer works with the system to develop input, output and dialogue specifications. For output, the terminal screen or the printed papers were used and for input, the data capture method is used.
System designers are responsible for the task and can use GUI (graphical user interface). For this, I have used Macromedia Dreamweaver and Phpmyadmin.
2.14.2.1.4 Package Design Specifications
The final design task involves packaging all the specifications from the previous design tasks into a set of specifications that will guide the computer programmer’s activities during the construction phase of the systems development methodology.
2.14.2.1.5 Update the Project Plan
Revaluation of the project is done. The project manager in conjunction with system owners and the entire team facilitates this tas
2.14.2.2 Buy Solution
If the DP Sign is willing to buy the website from the outsider then following is done:
2.14.2.2.1 Identify and Research Specific Products
In this task, we research technical alternatives. The requirements specify the functionality, features and critical performance parameters for our new website. Research and information are collected from internal standards, information services, trade newspapers, and periodicals offer. System Designer with the help of a project manager is responsible to complete the task
2.14.2.2.2 Solicit Proposals or Quotes from Vendors
The solicitation task requires the preparation of RFQ (Request for Quotations) and RFP (Request for proposal).

Analysis
3.1 Strategic Business Unit’s Analysis
DP Sign has different strategic business units and management as DP Sign is well aware that how to use these units strategically. In order to fully analyze the business units of DP Sign that are web development, online earning training, and printing, I have used different analysis which not only gives the true picture of the company’s different unit but it also gives the depiction of the overall industry analysis in which company is currently working. There are four types of Analysis which I have performed in order to explore the working of the organization.
3.1.1Web Development department Analysis
3.1.2 Online Earning department Analysis
3.1.3 PEST Analysis
3.1.4 SWOT Analysis
3.1.5 Five S’s of Workplace Organization.
All these analyses have been performed by getting data from real-time industry situation as well as the organization. Research articles, news articles, internship reports, manuals are being used in order to effectively analyze the working of the organization. The historical data for the analysis has been taken or a maximum of 5-7 years back while current data until 2009 has been used.
3.1.1 Web Development department Analysis
Present status of Website development in DP Sign
Though the Website development in Nepal is developing and every year many companies are being registered but a professional person is lacking in our country. DP Sign is also facing the same problem so it is hiring professionals from other countries. Like other companies in Nepal, DP Sign is also lacking local customers as our country is lacking the knowledge to use technology and computers.
But the use of technology and website in Nepal is also increasing thus DP Sign also has to focus on the local customers. Even personal websites are taking a market so DP Sign should focus on this site by reducing the costs but increase the volume of sale which ultimately leads to an increase in the profit.
Schools, colleges, institutions, shopping center are increasing thus DP Sign should focus in this sector also. One of the lackings of the DP Sign is that it lacks advertisement.
DP Sign has to face competition from:
Strong local market
New entrants in the international market
Competition from existing customers
Economic recession
From a strong local market, the competition has been arising from a few companies. These companies are well renowned not only locally but also internationally. In these local companies, DP Sign has been facing competition at website development. At locally and internationally DP Sign is facing the competition as the number of companies is increasing. As economic recession is a period of recession and throughout the global world is suffering from the economic crisis, in such a scenario, there is an effect on website development also.
In the context of DP Sign, the market capture internationally is very low in the context of other website company so the company should focus on maintaining international customers.
3.1.2 Online Earning department Analysis
In the context of DP Sign Online Earning, training generates about 15% of the Revenue. So this is also one of the most important departments of DP Sign but DP Sign is not focusing on it.
The Internet in Nepal is increasing. Some businesses and people are eager to earn online by sitting at home and being bosses of themselves so online earning has also a potential market to earn.
But DP Sign is not focusing on this sector and I suggest them to make a website to unite their team and the exchange of click can be done so that everyone can get benefits.
3.1.3 PEST Analysis
PEST analysis is the analysis which we tend to perform in order to analyze the external as well as the internal environment in which the organization is currently working. PEST analysis revolves around four things.
Political Environment
Economic Environment
Social Environment
Technological Environment
Political Factors
There are many factors, which entice the organization with the Government.
Tax policy
Quota
Cyber Laws
Online transactions law
Labor policy
Economic Environment
Recession, devaluation of the currency and the policy of the government have an adverse effect on the economy.
Social Factors
Due to an increase in the education and technology sector, the educational power of the customers is increasing at a speedy rate. They are becoming aware of the brands and the latest technology. Due to this, they are demanding a high technological website at a low price in the international market.
Technological Factors
Technology is also a key sector in terms of the external environment for website development. The technology is working as a substitute for manpower with more efficiency. DP Sign has to focus on following
Error reduction
Less labor cost
DP Sign should have to focus on maintaining the harmony between the factors of PEST analysis so that it can progress in its life cycle.
3.1.4 SWOT Analysis
Performing SWOT analysis involves the generation and recording of the strengths, weaknesses, opportunities, and threats in relation to a particular task or objective.
Strengths
Strong and Prominent International Image
Latest Technology
Competitive Workforce
Creativity and Innovation
Management Information System
ISO Certified Company
Locally Working(Expenses in NRs but earning in Dollars)
Weaknesses
Individualism
Low Production capacity
No opportunity for Training and Development
Lack of teamwork
Lack of continuity of Policies
Too much Specialized Jobs
Opportunities
New Emerging Markets
Bright Local Market
New Cyber laws and Policies
Implementation of technology and websites in government sector
Threats
Non-supportive government
Government Policies
Growing Competition
Political uncertainties
3.1.5 5 S’s of Workplace Organization.
I recommend the DP Sign to follow the 5 S’s techniques to promote workplace organization, ensure adherence to standards and foster the spirit of continues improvement.
The 1st S: Sort
To get rid of unwanted items, things should be in the right place so that it can be gain ant the right time. Decide what is needed to be kept, and what is not needed and to be discarded.
The 2nd S: Set Location and Limits
To locate a specific place for specific items of a specific quantity, where needed. Determine addresses for materials and equipment. Put them in that place and keep them there.
The 3rd S: Shine and Sweep
Shine and sweep mean to use cleaning to identify abnormalities and areas for improvement. Clean the workplace and at the same time visually sweep for abnormalities or out or control conditions.
The 4th S: Standardize
To consolidate the first 3 S’s by establishing standard procedures. Determine the best work practices and find ways of ensuring everyone does it the same “best” way.
The 5th S: Sustain
Sustain improvements and make further improvements by encouraging effective use of the ‘Check-Act-Plan-Do’ cycles. Keep all current improvements in place and develop an environment for future improvements.
3.2 What I would improve or do differently if I had the opportunity:
I could be better organized, especially with regards to the paperwork required for capital purchases and expense reporting for business travel.
I could learn to manage my time better, planning parallel execution of some short-duration activities when long-running operational activities are occurring.
This would reduce personal idle time when waiting for long-duration activities to complete.
Chapter 4
Recommendations
There are few things which can be implemented and improvements can be made.
There must be a career development opportunity for the employees so that they can work energetically in the organization as there is high turnover due to lack of information in the related sector.
Remuneration System must help in motivation as a better remuneration package can do more in this highly competitive environment.
The work environment at DP Sign is such that it does not encourage the staff to work effectively and I recommend that jobs should be such that the worker really enjoys what they are really doing.
The staff as an individual is good but as a team is very bad, this thing should be overcome by promoting the team-based culture by the company.
What I feel while working in DP Sign was that the top management is taking HRD as an expense rather than an investment as in the future the real capital or asset will be in the form of the workforce rather than monetary capital.
In DP Sign there are uses of advance technology so the employee outside the world cannot cope easily with the internal environment so the socialization process should perform while recruiting the new employee.
I suggest DP Sign to make a website to unite their online earning team and the exchange of click can be done so that everyone can get benefits.
There are problems in web hosting services as the mail is sent to the scams sector so it should be maintained and the reliable up to date time is 98% only so the web hosting services should be changed.
Chapter 5
Conclusion
During my internship training at DP Sign, I have learned a lot and my vision and practical exposure have broadened very much from my three months internship. In the website development and online earning sector, DP Sign is contributing a lot and is using modern technology to take the company to new horizons and is moving as per its slogan “A strategic partner of our clients, not a mere vendor”.
I have carried out my responsibilities and duties in the field of website designing and online earning by which I am capable to design and program website and started to earn online.
After doing my internship it becomes clear to me that books are only dealing with the ideal situation while in the real world it is not so, and you have to face many problems particularly in programming and designing field in which you are dealing with codes and the behavior of software to handle them. Besides this, I just came across with abstract and the concepts developed with thorough study able to make a vague mental image while working in a real scenario.
Further, I also concluded that 100 percent concentration, full care, analytical, descriptive, knowledge and communication skills are the key prerequisites for working in the real world.
Anyhow, precisely speaking this internship of three months is a memorable period for me during which I availed the opportunity to flourish my communication skills, polish my capabilities and abilities, upgrade my knowledge about the latest technology and application tools and broaden my vision and exposure towards practical life.
This internship proves better for me in two way, on one side it helps to develop a personality in me which exactly match the professionalism in web development and secondly it helps to strengthen my decision about the specialization in web technology as my personality exactly match the nature of the job.

PROGRAM WORKPLACE RELATIONSHIP
This project has proved to be very useful in putting the theoretical knowledge learned in college into practical knowledge. Through this project, the various subjects learned by us such as the principle of management, system analysis, and design, C programming, web technologies, Object-oriented languages, organizational behavior, and other programming have been put into use practically.
The subject matter of system analysis and design and other programming languages and web technologies learned theoretically were put into use in this project. Planning of the assignment, locating information sources, collecting and analyzing data, presenting charts and tables, programming, website designing and programming, understanding system and software as well as re-engineering them, etc. which are already studied by us in books was very helpful in putting it into practical experiences and preparing this project. The theoretical knowledge of web technologies, programming languages and managerial courses were helpful in carrying out the SWOT analysis, PEST analysis, and other analysis.
This program is very helpful in putting our theoretical knowledge into practical knowledge. All the subject matter studied by us in the previous semester was put into use while carrying out this project. Studying books is a different thing and going through all the things studied is different. This program has provided a platform to undergo real-life problems and experiences of business which will be fruitful to us in the coming years.

In this problem, you will analyze a profile log taken from a MongoDB instance. To start, please download sysprofile.json from Download Handout link and import it with the following command:
mongoimport -d m101 -c profile < sysprofile.json
Now query the profile data, looking for all queries to the students’ collection in the databaseschool2, sorted in order of decreasing latency. What is the latency of the longest-running operation to the collection, in milliseconds?
Suppose you have a collection called tweets whose documents contain information about thecreated_at time of the tweet and the user’s followers_count at the time they issued the tweet. What can you infer from the following explain output?
In this problem, you will be using an old weather dataset. Download weather_data.csv from the Download Handout link. This is a comma separated value file that you can import into MongoDB as follows:
mongoimport –type csv –headerline weather_data.csv -d weather -c data
You can verify that you’ve imported the data correctly by running the following commands in the mongo shell:
> use weather
> db.data.find().count()
> 2963
Reading clockwise from true north, the wind direction is measured by degrees around the compass up to 360 degrees.
90 is East
180 is South
270 is West
360 is North
Your assignment is to figure out the “State” that recorded the lowest “Temperature” when the wind was coming from the west (“Wind Direction” between 180 and 360). Please enter the name of the state that meets this requirement. Do not include the surrounding quotes in providing your answer.
Answer is:
New Mexico
Write New Mexico and submit.
If you need query then following is the query to retrieve the data
If you had installed Xampp in D:/ folder then follow the following steps, if you have installed in C:/ or another folder then replace D with respective folder name.
Open up the Xampp control panel and stop Apache (Ensure that you don’t have it running as a service.
Navigate to D:/xampp/apache/conf/extra or wherever you installed Xampp
Open up your text editor with administrative privileges and open up httpd-vhosts.conf found in the D:/xampp/apache/conf/extra folder
At the very bottom of the file paste the following (check if it exists there already)
<VirtualHost *:80>
DocumentRoot “D:/xampp/htdocs”
ServerName localhost
</VirtualHost>
Without that line of code, you will lose access to your default htdocs/ For eg: http://localhost/ will be inaccessible.
Now copy and paste the code below: <VirtualHost *:80> DocumentRoot “D:/xampp/htdocs/webocreation” ServerName webocreation.dev ServerAlias www.webocreation.dev <Directory “D:/xampp/htdocs/webocreation”> AllowOverride All Require all Granted </Directory> </VirtualHost>
Now we head over to our Windows Hosts File, to edit the HOSTS. File will be located at C:/Windows/System32/drivers/etc/hosts, where hosts is the file. 127.0.0.1 localhost
Look for the line above and enter your site mimicking the layout 127.0.0.1 localhost 127.0.0.1 webocreation.dev
Change this to the domain name you choose earlier
Change it to reflect the lines above (if you have problems saving it meant you didn’t have your text editor running in admin mode.
Restart Apache and test to make sure it is working.
It is not recommended to change the default files of OpenCart as if you upgrade then all changes will be lost so we have seen one solution to achieve your requirement by changing the header.tpl. Open catalog/view/theme/YOUR_THEME/template/common/header.tpl Find the following lines of code:
For many sub-categories, you can make multiple columns of sub-categories in OpenCart. While inserting the category, in the data tab, insert the “Columns” value to show multiple columns. You can see examples of the “MP3 Players” category and its sub-categories in the default installation.
Products to show without the add to cart button, another Opencart free module “Coming Soon Products module OpenCart version 2.0”. When you enabled this module, you will be able to see the products which available date is greater than today.
The module will look like below:
Admin section will look like:
Download Coming Soon Future Products free module from the link below:
Upload the files in the root folder to your server, no file is overwritten.
Then activate the “Future Products” module.
Activating the “Future Products” module:

While working as drupal developer in multi language Drupal 7 site you may find EntityFieldQuery class which allows finding entities based on entity properties and keep on getting confused with the propertyCondition and entityCondition for language translation.
Below example of entity field query helps me to find node main language specific featured blog post and
global $language;
$query = new EntityFieldQuery;
$query->entityCondition('entity_type', 'node')
->entityCondition('bundle', $bundletype)
->propertyCondition('status', NODE_PUBLISHED) // in case you need it
->propertyCondition('language', $language->language)
->fieldCondition('field_featured_blog', 'value', '1', "=")
->propertyOrderBy('changed', 'DESC')
->range(0,1);
$query->execute();
Below will find data as per the translated entity based language featured blog.
global $language;
$query = new EntityFieldQuery;
$query->entityCondition('entity_type', 'node')
->entityCondition('bundle', $bundletype)
->propertyCondition('status', NODE_PUBLISHED)
->entityCondition('language', $language->language)
->fieldCondition('field_featured_blog','value', '1', "=")
->propertyOrderBy('created', 'DESC');
$query->execute();
When you do print_r($query), then you will get following:
Full details of EntityFieldQuery at:
https://api.drupal.org/api/drupal/includes%21entity.inc/class/EntityFieldQuery/7.x
The function defaults to either = or IN depending on the value param as an array or string.

The protocol that use newlines to separate messages, we’ll call this protocol Line Delimited JSON (LDJ). There are no line breaks in JSON messages. Although JSON is whitespace agnostic it ignores whitespace outside of string value.
Serializing Messages with JSON
Let’s develop the message-passing protocol that uses JSON to serialize messages. Each message is a JSON-serialized object, which is a hash of key-value pairs. Here’s an example JSON object with two key-value pairs:
{"key":"value","anotherKey":"anotherValue"}
The net-watcher service we’ve been developing in this chapter sends two kinds of messages that we need to convert to JSON:
When the connection is first established, the client receives the string
Now watching target.txt for changes…
Whenever the target file changes, the client receives a string like this: File “target.txt” changed: Sat Jan 12, 2013, 12:35:52 GMT-0500 (EST)
We’ll encode the first kind of message this way:
{"type":"watching","file":"target.txt"}
The type field indicates that this is a watching message the specified file is now being watched.
The second type of message is encoded this way:
Here the type field announces that the target file has changed. The timestamp field contains an integer value representing the number of milliseconds since midnight, January 1, 1970. This happens to be an easy time format to work within JavaScript. For example, you can get the current time in this format with Date.now().
To relieve the client program from the danger of split JSON messages, we’ll implement Line Delimited JSON (LDJ) buffering client module. Then we’ll incorporate it into the network-watcher client.
First, let’s have a look at how the Node does inheritance. The following code sets up LDJClientto inherit from EventEmitter.
LDJClient is a constructor function, which means other code should call new LDJClient(stream) to get an instance. The stream parameter is an object that emits data events, such as a Socket connection. Inside the constructor function, we call the EventEmitter constructor on this. That line of code is roughly equivalent to calling super() in languages with classical inheritance.
Finally, we call util.inherits() to make LDJClient’s prototypal parent object the EventEmitterprototype. If this sounds cryptic to you, don’t worry. It’s like saying classLDJClientinherits from EventEmitter in languages with a classical inheritance model. It means that if you look for a property on an LDJClientand it’s not there, the EventEmitteris the next place to look
Exporting Functionality in a Module
Let’s pull together the previous code samples and expose LDJClientas a module. Open a text editor and insert the following: /ldj.js

Hi, today we are publishing another free Opencart module “Sidebar Shopping Cart” and we made this for OpenCart version 2.0.3.1. Problem is we cannot edit js file with vQmod so you need to override the common.js file. But we have described where you need to put the extra code below in this post.
JS/CSS files are rendered at the browser level, not at the server level, so vQmod has no effect on these files. You can, however, create new files and use vQmod to alter the tpl files to point to these new CSS/JS files.
Output after installing the module is shown as in the image below:
Sidebar Shopping Cart
You can see how we copied the header cart section and show it as a module inside the cart box or side shopping cart. You can show anywhere you like as this is a module so you can show at the left column, right column or top content or bottom content.
Upload the files in the root folder to your server, the common.js file is overwritten so if you have any kind of custom javascript used then please transfer to the file and upload the common.js.
Then activate the Shopping Cart module.

Then click on Extensions on the left menu
After that Click Modules and go to “Shopping Cart” in the modules list
Then click the green button to install the module (see the image below)
installation_of_module
Then click the blue edit button
After that, you will see the form which has the status field, select “Enabled” and then click the Save button.
Your module is active and is ready to use in the layout.
Setup layout for the sidebar shopping cart at home page:
From the admin section go to System >> Design >> Layouts.
You will see a list of layouts, from which edit the “Home” layout.
Then click Blue add the button to add rows at module section which is shown in the image below:
siderbar_shopping_cart_installation
Second, you choose the Shopping Cart in the module column and Column right in the Position column and insert the sort order as required.
Then click save button
Your custom sidebar shopping cart is showing in the right column of the home page. Likewise, you can show in many other layouts and pages.
Codes to added to common.js if you don’t want to override it:
Open catalog/view/javascript/common.js
Find the following lines of code
$('#cart > ul').load('index.php?route=common/cart/info ul li');
In part 1 we showed how to activate google reCaptcha in contact us page, now we show how to show it on the registration page. Although it is not that simple as showing in the contact us page, we have to make some changes in code. For now, we are changing directly into the default file although it is not recommended :). We will try to provide OCMOD soon in the next post so you need to wait for the next post.
First go to catalog/language/english/account/ and open register.php file.
Add the following code to the end of the file. $_['text_google_recaptcha']= 'Google reCaptcha'; $_['error_captcha'] = 'Verification code does not match the image!';
Save the file
Changes to be made at the controller file:
Go to catalog/controller/account/ and open register.php file
Find the following lines of code which is inside the index method $data['column_left'] = $this->load->controller('common/column_left');
Just above that code paste following code $data['text_google_recaptcha'] = $this->language->get('text_google_recaptcha'); if (isset($this->error['captcha'])) { $data['error_captcha'] = $this->error['captcha']; } else { $data['error_captcha'] = ''; } if ($this->config->get('config_google_captcha_status')) { $this->document->addScript('https://www.google.com/recaptcha/api.js'); $data['site_key'] = $this->config->get('config_google_captcha_public'); } else { $data['site_key'] = ''; }
Now find the following lines of code which is inside the validated method. // Agree to terms if ($this->config->get('config_account_id')) { $this->load->model('catalog/information'); $information_info = $this->model_catalog_information->getInformation($this->config->get('config_account_id')); if ($information_info && !isset($this->request->post['agree'])) { $this->error['warning'] = sprintf($this->language->get('error_agree'), $information_info['title']); } }
Now above that code paste following code. if ($this->config->get('config_google_captcha_status')) { $recaptcha = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($this->config->get('config_google_captcha_secret')) . '&response=' . $this->request->post['g-recaptcha-response'] . '&remoteip=' . $this->request->server['REMOTE_ADDR']); $recaptcha = json_decode($recaptcha, true); if (!$recaptcha['success']) { $this->error['captcha'] = $this->language->get('error_captcha'); } }
Save the file and your controller is ready
Changes to be made at the template theme file:
Go to catalog/view/theme/default*/account/ and open register.tpl, default* means if you are not using default theme then it will be theme name you are using.
Find the following line of code <?php if ($text_agree) { ?>
Just above the code above, paste the following code <fieldset> <legend><?php echo $text_google_recaptcha; ?></legend> <?php if ($site_key) { ?> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <div class="g-recaptcha" data-sitekey="<?php echo $site_key; ?>"></div> <?php if ($error_captcha) { ?> <div class="text-danger"><?php echo $error_captcha; ?></div> <?php } ?> </div> </div> <?php } ?> </fieldset>
Save the file
Now go to your registration page and you will see the page like below:
Activate google ReCaptcha at registration page in Opencart
