Introduction to Django
To help you understand the fundamentals of Django and build a strong foundation in Django.
Knowing a programming language will only get you so far ๐ . You'll never get things done before the deadline โ if you have to build everything yourself. It's a great idea to pick up a framework โ๏ธ once you've mastered a programming language ๐ฐ . Django is the most popular Python full-stack framework. Once you've mastered it, creating web applications will be quick and extremely easy! โจ
In this blog, we will look at some features of Django and demonstrate its ease of use ๐ . If you are excited as I am, let's dive in ๐ค .
Assumptions for the reader:
- You have a basic knowledge of Python ๐๐ป
- You are excited!๐๐ป
Before we get there, letโs understand a web framework and why we need it. ๐ค
A web framework is a server-side application framework designed to support the development of dynamic websites ๐ป . Django is one such framework available for Python ๐ฐ . Basically, Django is a code library that makes the life of a web developer much easier ๐ฉโ๐ปโ .
But how? How exactly does a web framework helpโ
A web framework is a collection of class/APIs with predefined codes that you can use in your program to add a feature to your web application ๐ .โ
So, we have a web framework with a set of APIs โ . We just need to add our snippets of code wherever required โ and done! ๐ That solves the problem.
So, what is Django?
The Web framework for Perfectionists with Deadlines.
๐ Simply defined, Django is an open-source Python web framework that allows web and app developers to create and deploy big projects โโ๐จโ๐ป โrapidly, safely, and in a consistent, "clean" style. ๐ It comes with a set of out-of-the-box tools that support, enrich, and accelerate ๐จ the traditional web development process, allowing you to complete otherwise difficult tasks quickly and to a high standard. โ๏ธ
It also makes working with databases a lot easier ๐ฐโโโ. You don't need to work directly with a database because Django takes care of creating the database on the go ๐ค๐ป as the user creates models. You can easily swap from one SQL database to the other at the same time.๐ฏ With Django, you can have a fully functional, secure, and admin-editable website in just a few hours. ๐
Nevertheless, it's a framework worth having on your portfolio!๐คฉ
Features of Django
๐ก Some features Django offers us are:
Is there anything built with Django that I'm familiar with?๐ค
You have, without a doubt! ๐๐ป A few of them are listed here:
Django MVT Architecture
๐ Django follows the MVT Pattern. What is MVT?
The MVT pattern is a type of software design pattern. ๐๐ป It is made up of three major components:
- ๐ Model - It aids in database management. Your database is defined in the backend โ.
- ๐ View - This executes the business logic and interacts with the model to carry data and render a template โ.
- ๐ Template - It handles the User Interface โ.
๐ก So, the process is pretty simple. A user sends the request via the browser โก๐. Django acts as a controller โ, checking the URL for available resources and the associated view is called ๐๐ป. The model and template interact with the view ๐ค๐ป, which retrieves data from the database via the model โฉ, formats it, and renders with the help of the template as a response. โ
Why Djangoโ
- ๐ ORM - Here, you can define your data models โ.
- ๐ Django comes with a fully-featured and secured authentication system โ๐จโ๐ปโ. It handles your user counts, permissions, etc โ.
- ๐ It provides a powerful and production-ready interface to manage content on your site ๐. If you want to add a user or create a group โ๐ฑโ, Django has an in-built admin interface created automatically โ.
- ๐ Django offers full support for translating into different languages plus locale scale-specific formatting (e.g., dates, time, time zones) โ.
So, where do I begin with?๐ฏ
No worries at all! ๐ค AI Probably has got you covered.๐๐ป We are soon launching a FREE 3-hour crash course on โPython with Djangoโ. ๐ฏ
๐ก This course will teach you Django from the ground up ๐, so you don't need any prior knowledge to get started, just a basic understanding of Python ๐ฐ. We start from the basics โ๏ธ and work our way up to understanding the ๐ Django MVT architecture, ๐ setting up SQLite Database , ๐ adding views and templates to our website, ๐ handling requests and responses - step by step ๐. This course has it all covered in great detail ๐ and backed up with a complete example course project โโ๐จโ๐ปโ.
Whatโs more? We have gamification-based Learning! โ๐ฎโ What does that mean?
๐ That means you learn complex topics through interactive games ๐ฎ on our website! โ
With our latest advancement in Gamified Learning methods, you now stand a chance to improve your learning engagement and see your skills grow exponentially! ๐
Letโs build a project now!
The Django community ๐จโ๐ฉโ๐งโ๐ฆ is a vibrant group of talented programmers โโ๐จโ๐ปโ, and there are numerous tools to help you get started. Also, excellent documentation provided by Django; extremely straightforward and very informative ๐.
๐ก Let us create a small project using Django .
Now, to begin, you'll need Python installed ๐ฐ. Python comes pre-loaded on OS X and Linux-based systems, so if you're using one of those, you're good to go โ. If you're using Windows, โ๐จโ๐ปโ you'll need to download and install Python from the Python website .
Now, all we have to do is open up a terminal ๐ป and run
pip install django
to install Django without impacting anything else. The most recent version of Django will be downloaded and installed โ. To get started with Django, we'll need to create a project. Navigate to the folder โช (using terminal) where you want to create your project and type
django-admin startproject myproject
๐ If you look inside this directory, you'll notice that it has created a myproject
folder with the following structure:
myproject/
manage.py
myproject/
__init__.py
settings.py
urls.py
wsgi.py
โ๐ป This is the default project structure for a Django project. Django comes with a built-in server that you may use to test your app โ๐ปโ. It makes it very easy to get your projects up and running ๐. Run the server:
python manage.py runserver
๐ Youโll see the server startup and direct you towards http://127.0.0.1:8000.
What does each of these files doโ
When you run startproject
, four files are generated: manage.py
, settings.py
, urls.py
, and wsgi.py
.
- ๐ The
manage.py
file replaces thedjango-admin
command we used earlier; it is your main entry point โช into your application and runs any management commands related to our project, such as creating an admin user. It is extremely unlikely that you will need to modify this file ๐ซ . - ๐ The
settings.py
file contains all of our project's settings ๐, such as the project's name, the URL it will live on, and so on. - ๐ The
urls.py
file is the one that contains the routing information for all Django requests; it maps various URLs to their corresponding views ๐ฏ . - ๐ When you deploy your project to a server, the
wsgi.py
file is used. It enables a WSGI HTTP server, such as Gunicorn, to mount your application and allows HTTP requests ๐.
