A It acts as a command-line utility that lets you interact with the Django project, like running the server or migrations.

B It contains the main settings and configuration for the Django project.

C It stores the database models and schema definitions.

D It is the template file that defines the HTML layout for the project.

💡 Hint

Think about what you type in the terminal to start the server or make database changes.

What error occurs if urls.py is missing in a Django app?

If you create a new Django app but forget to add a urls.py file and try to include its URLs in the main project, what error will Django raise?

A TypeError: 'NoneType' object is not callable

B TemplateDoesNotExist error

C OperationalError related to the database

D ModuleNotFoundError: No module named 'app_name.urls'

💡 Hint

Think about what happens when Django tries to import a missing file.

If urls.py is missing in the app, Django cannot find the module when you try to include it in the main urls.py. This causes a ModuleNotFoundError.

C A templates/ folder with HTML files is created.

The startapp command creates a folder with several default files and a migrations folder to help you build your app.

Which folder in a Django project holds the HTML files for rendering views?

In a Django project, where should you place your HTML template files so that Django can find and render them properly?

A Inside a <code>templates/</code> folder either at the project level or inside each app folder.

B Inside the <code>static/</code> folder alongside CSS and JavaScript files.

C Inside the <code>migrations/</code> folder of each app.

D Directly inside the main project folder with <code>settings.py</code>.

💡 Hint

Templates are not static files but files used to generate HTML dynamically.

Django looks for HTML templates inside templates/ folders. These can be at the project root or inside individual apps to organize templates.
