TWeb development always remains to be at the top of every enthusiastic techie’s bucket list. In its core, Web development is the practice of developing and maintaining web pages and web applications. So, let’s take a deep dive into one of the most trending web development frameworks today – Django.
So now the question rises here what makes this framework so awesome? Why do web developers use Django for web development? One best thing about Django is that it is built on Python, which is an incredibly robust and dynamic programming language. Moreover, Django is an open source web framework, a newly released version Django 2 has the whole new set of features and capabilities!
What is Django?
Django is a marvelous framework for web developers because it provides the support required for database-driven websites that contain user authentication, contact forms, file uploads, and more. Instead of developing all these from scratch, you can use the Django framework and utilize these components that are built in, and the web developers can focus their time on improving the web applications instead.
Due to this, Django gives high-quality and transparent code writing, which is an essential perspective of this framework. Even it offers various other features like an automatic administration Interface or the Object Relational Mapping(ORM).
Why Choose Django?
Let’s take a look at few of the features why most of the web developers choose the Django web development that makes this framework an absolute no brainer for web developers:
- Secure: Django is developed on python due to which, Django also reaps the benefits of the widely active Python web developers community. It helps the Django web developers to avoid many security mistakes such as cross-site scripting, SQL injection, clickjacking, and CSRF. Django offers a user management system which allows you to manage users better.
- Fast: Django web development allows with clean and pragmatic design and so the Django web developers to complete their apps as fast as possible. Django takes much care of the hassle of web development without needing to reinvent the wheel. The code reusability is essential for any Django web developer.
- Scalable: Django code is very highly scalable as technology is evolving, writing code and executing them is essential. Many high-value websites like Instagram and Disqus utilizes Django for its back-end process. Django allows with a proper framework to grow your website and add more functionalities.
- Set of Packages: Django provides tons of components and libraries which help you speed up the entire web development process. Everything that is needed for the Django web development will be taken care of by Django frameworks such as standard libraries, packages, user authentication, site maps, content administration, and many others.
- Versatile: Django is used to build all sort of things from the content management system to social networks to scientific computing platforms. All this tells Django is exceptionally versatile in all fields.
Django Architecture
Let’s check the Django Architecture. In general, Django follows an MVC-MVT architecture.
MVC is used for developing web publications in which we break the code into multiple segments. Here we have three layers Model, View, and Controller.
- Model: This is the back end where you can determine your database. Model is used for caching and securing your data.
- Views: View is all about the presentation whatever the user can view is referred to as View. In Django templates, Views are HTML.
- Controller: Controller acts as the medium. It is a business trick which communicates with the model and view.
So far we are clear with MVC, let’s take a look at what MVT means.
MVT Stands for Model View Template in which every user interface has a pre-defined template. Let’s understand with an example in a better way. Imagine that you want to write various static HTML forms like Greetings to user1, Greeting to user2, and so on. Now with Django template, you will have only one file that prints hello along with the variable name. Python Django templates excel at maximizing code reusability by allowing variables to be substituted within the template using logic!
Now here raise the question, where is the controller? – In the case of MVT, Django has inbuilt functionality of taking responsibility of the Controller part. It was clear with the Architecture; let’s understand how Django works.
The image depicts a template functioning as the front end, interacting with the View. The Model serves as the backend in this architecture. Here the View will access both the model, the templates, and maps it to a URL after this, Django plays the role of controller and servers it to the user.
This sound so simple. Let’s get started by Installing Django and Web developing Apps.
Django Installation
Django is a Python-based web Framework. First, you need to install Python by visiting https://pythin.org/downloads/. Once done with the download, install, and run it. After installation, make sure to check the version you installed, using the below code as follow:
To install Django, first, you need to know pip concept, which is a package manager for python. Using this, pip makes installing and uninstalling all the packages of Python much simpler. Even you need to install pip on your system, for this, you need to go to https://pip.pypa.io/en/latest/installing/ and follow the instructions.
Then you can build an implicit environment for all your projects like this:
Install Django
Pip commands within a VM allow you to efficiently connect Django. To ensure your VM is active, just run the following command:
Using this you can download and install all the latest Django packages. Now you are got ready to start with your own Django web development.
Different versions of Django Framework
Let us check some of the versions of the Django web framework.
- Django 1.11
