Web Development with Python Django Framework?

Web Development is an evergreen domain with plenty of opportunities. Now that you have landed on this blog, you are either a web developer or aspiring to be one. Either way, you should know it is a skill in high demand for quick web project development and has been nicknamed as the web framework for perfectionists with deadlines. I am going to talk about one of the most trending web development frameworks Django and will help you get started with it. In this Django tutorial, I will introduce you to the fundamental concepts of Django and help you understand how everything fits together while building a Django application.

Why Web Framework and Why Django?

Before understanding Django, let’s first understand why do we need a web framework? A web framework is a server-side application framework which is designed to support the development of dynamic websites. With the help of a framework, you don’t have to handle the hassles of web development and its various components. Therefore, it makes the life of a web application developer much easier as they don’t have to code from scratch. There are various web development frameworks available in the market. Some of them are listed below:

JS

Angular

Ruby on Rails

Express React

One of the highlights of Django is that it is built on python. For several years python has been the most popular programming language and continues to be a favorite among the skilled programmers. Hence, Django delivers transparent and high-quality code writing, making it important for the developers as well as the customers. It has various other advantages as it has an automatic administration interface, Object-relational mapper(ORM) and many more. So let’s understand what exactly it is.

What is Django?

Django is an open source web framework which was named after Django Reinhardt. It follows the principle of “Don’t Repeat Yourself”. As the name says, this principle is all about keeping the code simple and none repeating. Django is also a high level, MVT architect which stands for Model View Template.

Django Architecture:

Django follows MVC- MVT architecture. MVC stands for Model View Controller. It is used for developing web publications, where we break the code into various segments. Here we have 3 segments, model view, and a controller.

Model – Model is used for storing and maintaining your data. It is the backend where your database is defined.

Views – In Django templates, views are in html. View is all about the presentation and it is not at all aware of the backend. Whatever the user is seeing, it is referred to a view.

Controller – Controller is a business logic which will interact with the model and the view.

Now that we have understood MVC, let’s learn about django MVC pattern.

MVT stands for Model View Template. In MVT, there is a predefined template for user interface. Let’s take an example, say you want to write several static html forms like hello user 1, hello user2 and so on. With template, you will be having only one file that prints hello along with the variable name. Now this variable will be substituted in that particular template using some jinja logic. That’s the magic of template, you don’t need to rewrite the code again n again!!
