Python Django Basics

In this tutorial,we will cover some basics of Django and topics which we will cover are:Design principles for Django framework,Advantages of Django, and Popularity of Django.

Let us first start with the Design Philosophy of the Django framework.

Design Principles of Django Framework

The Django framework mainly uses a set of design principles that helps in producing one of the most productive web development processes as compared to many other web frameworks.Also the Django framework incorporates with a set of design principles and trade-offs that when combines make it one of most productive frameworks in order of building the features needed by most medium web applications to large web applications.

Let us discuss those design principles one by one:

1. Quick Development
   To Make web development fast is a tedious aspect of Web framework in 21st century.Thus Django Framework should allow incredible and superfast development.

2. Less Code
   The Django applications should use as little code as possible .This framework should take full advantage of Python’s dynamic capabilities, such as introspection.Less code in turns indicate quicker development.

3. Loose Coupling
   The main aim of Django’s stack is loose coupling and tight cohesion.That is the various layers of the django framework shouldn’t know about each other unless it is absolutely necessary.Thus each element of the Django stack are independent of each other.

4. Consistency
   This principle simply means that Django framework should be consistent at all the levels. Consistency should be applied on to everything from the low-level (The Python coding style that is used) to high-level (that is the experience of using Django).

5. Don't Repeat Yourself(DRY)
   This prnciple means that every distinct concept and/or piece of data should only live in one, and only one place. Because of the reason that Redundancy is so bad and on the other hand Normalization is good.Thus the Django framework should deduce as much as possible from as little as possible.(which simply means that everything that is to be developed should be developed only in exactly one place instead of repeating it again and again)

6. The Clean Design
   The Django framework should strictly maintains a clean design throughout its code and which also makes it easy to follow best web-development practices.

Now it's time to take a look at the advantages of the Django Framework

Advantages of Django Framework

Given below are the advantages of the Django Framework of Python:

• Fast
  The Django Framework has been designed in order to help the developers to make an application which is as fast as possible. From the idea, production to release, Django framework helps in making application that is both cost effective and efficient. Thus this framework has becomes an ideal solution for developers whose primary focus is on deadlines.

• Administration GUI
  The main advantage of this framework is that it provides us an incredible ready-to-use user interface for the administrative activities.

• Fully Loaded
  This framework works in such a way that it includes a dozens of extras things to help with user authentication, site maps, content administration, RSS feeds and much more such things. With the help of these aspects it help in carrying out the web development process completely.

• Development Environment
  This framework mainly comes with a lightweight web server whose task is to facilitate end-to-end application development and testing.

• Secure
  It is the key advantage of this framework that with this it is properly ensured that developers don’t commit any mistakes and that too related to security. Some of the most common mistakes include SQL injection, cross-site request forgery, clickjacking and cross-site scripting. Because In order to manage usernames and passwords effectively the user authentication system is the key.

• Versatile
  This framework is versatile because it helps in the Content management, managing scientific computing platforms, and even management of big organizations efficient;ly.

• Scalable
  In order to meet the heaviest traffic demand this framework is beneficial; because the busiest sites are using this medium to quickly meet the traffic demands.

• Multilingual Support
  This framework supports the multilingual websites with the help of its built-in internationalization system. Thus you can easily develop your website supporting multiple languages.

• Open Source
  This framework is an open source web application framework. It is available publicly without any cost. You can download it along with its source code from the public repository. Also,Open source reduces the total cost of the application development.

• Object-Relational Mapping support
  This framework provides a bridge between the data model and the database engineand is also supports a large set of database systems which includes:MySQL, Oracle, Postgres, etc. This framework also supports NoSQL database through the help of Django-nonrel fork. For now the only NoSQL databases supported are MongoDB and google app engine.

Popularity of Django Framework

Now let us dicuss about the Popularity of Django Framework.As this framework is widely accepted and various well known sites using this framework are given below:

1.Instagram

2.Youtube

3.Spotify

4.Bitbucket

5.Disqus

6.Dropbocx

7.Mozilla

8.Pinterest

9.Eventbrite

10.The Washington Post

Summary

In this tutorial we had covered various design principles of the Django framework,then we had covered the Advantages of using Django framework and then we had discussed the Popularity of this framework.In our next tutorial we will cover the Installation of this framework.
