What is the first step to install Django REST Framework (DRF)?

You want to start using Django REST Framework in your project. What is the correct first step?

A Create a new app named 'rest_framework' using manage.py

B Add 'rest_framework' to INSTALLED_APPS before installing the package

C Run the command: pip install djangorestframework

D Run the command: django-admin startproject rest_framework

💡 Hint

Think about how Python packages are added to your environment first.

The first step is to install the DRF package using pip. Only after installation can you add it to your Django settings.

What happens if you forget to add 'rest_framework' to INSTALLED_APPS?

After installing DRF, you forget to add 'rest_framework' to your Django settings INSTALLED_APPS. What will happen when you run your server?

A Your project will crash immediately on startup with a syntax error

B The server will run normally but DRF features will silently fail without errors

C Django will automatically add 'rest_framework' to INSTALLED_APPS for you

D Django will raise an error about missing 'rest_framework' app when you try to use DRF features

💡 Hint

Think about how Django knows which apps are active.

Django requires apps to be listed in INSTALLED_APPS to load their configurations. Missing 'rest_framework' causes errors when DRF features are used.

📝 Syntax

advanced

Which code snippet correctly adds DRF to INSTALLED_APPS in settings.py?

Select the correct way to add Django REST Framework to the INSTALLED_APPS list in your settings.py file.

Django

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    # other apps
    # Add DRF here
]

A 'rest_framework' in INSTALLED_APPS

B INSTALLED_APPS += ['rest_framework']

C INSTALLED_APPS.append('rest_framework')

D INSTALLED_APPS = 'rest_framework'

💡 Hint

Think about how to add an item to a Python list.

To add 'rest_framework' to INSTALLED_APPS, you can use list concatenation with += or add it directly in the list. Option B correctly adds it.

❓ state_output

advanced

What is the output when running 'python manage.py migrate' after installing DRF but before adding it to INSTALLED_APPS?

You installed DRF but forgot to add it to INSTALLED_APPS. You run 'python manage.py migrate'. What happens?

A Migrations run successfully without any DRF migrations applied

B You get an error saying 'No module named rest_framework' during migration

C Migrations fail with an error about missing 'rest_framework' app

D The command runs but creates empty migration files for DRF

💡 Hint

Think about what migrations Django applies based on INSTALLED_APPS.

Migrations only run for apps listed in INSTALLED_APPS. Since DRF is not listed, no DRF migrations run but others do.

🔧 Debug

expert

Why does this error occur: 'ModuleNotFoundError: No module named rest_framework'?

You run your Django project after adding 'rest_framework' to INSTALLED_APPS but get this error. What is the most likely cause?

A You forgot to install the djangorestframework package with pip

B You added 'rest_framework' to INSTALLED_APPS but misspelled it as 'restframework'

C Your Python version is too old to support DRF

D You need to restart the Django server after adding 'rest_framework'

💡 Hint

ModuleNotFoundError means Python cannot find the package in your environment.

This error means the DRF package is not installed in your Python environment. Adding it to INSTALLED_APPS alone is not enough.
