DRF installation and setup in Django - Step-by-Step Execution

Concept Flow - DRF installation and setup

Start: New Django Project

↓

Install DRF package

↓

Add 'rest_framework' to INSTALLED_APPS

↓

Run migrations

↓

Create API views and serializers

↓

Run server and test API

This flow shows the steps to add Django REST Framework to a Django project, from installation to running the API server.

Execution Sample

Django

pip install djangorestframework

# settings.py
INSTALLED_APPS = [
    ...
    'rest_framework',
]

python manage.py migrate

This code installs DRF, adds it to the project settings, and applies migrations.

Execution Table

Step	Action	Result	Notes
1	Run 'pip install djangorestframework'	DRF package installed	Ready to use DRF in project
2	Add 'rest_framework' to INSTALLED_APPS	'rest_framework' registered	Django knows to load DRF
3	Run 'python manage.py migrate'	Migrations applied	DRF database tables created if needed
4	Create API views and serializers	API endpoints ready	Prepare to serve data
5	Run 'python manage.py runserver'	Server running	API accessible at localhost
6	Test API with browser or tool	API responds	Verify setup success

💡 Setup complete, API ready to use

Variable Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	After Step 5
DRF package	Not installed	Installed	Installed	Installed	Installed and active
INSTALLED_APPS	No 'rest_framework'	No change	Includes 'rest_framework'	Includes 'rest_framework'	Includes 'rest_framework'
Migrations	Not applied	Not applied	Not applied	Applied	Applied
Server status	Stopped	Stopped	Stopped	Stopped	Running

Key Moments - 3 Insights

Why do we add 'rest_framework' to INSTALLED_APPS after installing the package?

Adding 'rest_framework' to INSTALLED_APPS tells Django to load DRF features; without it, DRF won't work even if installed (see execution_table step 2).

What happens if we skip running migrations after adding DRF?

Skipping migrations means DRF's database tables won't be created, which can cause errors when using features that need database models (see execution_table step 3).

Why do we test the API after running the server?

Testing confirms the API endpoints respond correctly, verifying the setup is successful and the server is running (see execution_table step 6).

Visual Quiz - 3 Questions

Look at the execution_table, what is the result after step 2?

A DRF package installed

B 'rest_framework' registered

C Server running

D Migrations applied

💡 Hint

Check the 'Result' column for step 2 in execution_table

At which step does the server start running?

A Step 5

B Step 4

C Step 3

D Step 6

💡 Hint

Look at the 'Action' and 'Result' columns in execution_table for server status

If we forget to add 'rest_framework' to INSTALLED_APPS, what will happen?

A Server won't start

B Migrations will fail

C DRF features won't load even if installed

D API will work normally

💡 Hint

Refer to key_moments about importance of INSTALLED_APPS

Concept Snapshot

DRF Installation & Setup:
1. Run 'pip install djangorestframework'
2. Add 'rest_framework' to INSTALLED_APPS in settings.py
3. Run 'python manage.py migrate' to apply migrations
4. Create API views and serializers
5. Run server with 'python manage.py runserver'
6. Test API endpoints to confirm setup

Full Transcript

To set up Django REST Framework (DRF), first install it using pip. Then, add 'rest_framework' to your Django project's INSTALLED_APPS list so Django loads DRF features. Next, run migrations to prepare the database. After that, create your API views and serializers to define how data is handled. Finally, run the development server and test your API endpoints to ensure everything works. This process enables your Django project to serve RESTful APIs using DRF.
