Getting started with Django

 

• Back-end web framework.
• Free, open source and written in Python.
• It makes it easier to build web pages using Python.
• Follows the MVT design pattern
• The data is delivered as an Object Relational Mapping (ORM)

Django serves pages in what way?

• When the client sends a request to the server, it checks the "urls.py" file for the right match and calls the view that matches the URL.
• The views are written inside the "views.py" file, which checks for the respective models within the "models.py" file.
• The view sends the data from the model to the corresponding template file (which contains HTML and Django tags) and serves the template to the client.

Create a virtual environment

Before creating a project and working on it, it's better to create a virtual environment for it. Because there are many libraries, you may want to include them in your project since they don't need to be installed globally. You can create a virtual environment in this way.

Note*: Activate your virtual environment before continuing with the following steps.

Install Django

You can install Django by providing the below command in the terminal.

# pip install Django

Check the installed version of Django.

# django-admin --version

Create and Run a Project

To create a project, you can use the django-admin command.

# django-admin startproject project_name

If you don't want to create a new project folder with the name of your project, you can do like this way

# django-admin startproject myproject .

To run this project

# cd project_name

# python manage.py runserver

Then go to this URL in your browser. 127.0.0.1:8000

Create an Application 

To create an application you can use the 'startapp' command with the application name.

# python manage.py startapp myapp

Migrations

Django uses migrations to propagate model changes you make into your database schema.

# python manage.py makemigrations

# python manage.py migrate

Django admin panel

To access the Django default admin panel you need to create a super user account.

# python manage.py createsuperuser

Now you can access the admin panel using this URL.

http://127.0.0.1:8000/admin/
