Interview Questions
Django is a high-level Python web framework that promotes rapid development and clean design. Key features
include an admin interface, ORM for database interactions, and built-in security protections.
Middleware are functions that process requests and responses globally. They can be used for tasks like
authentication, logging, and modifying requests or responses. They are configured in the MIDDLEWARE
setting.
Django handles requests by processing them through middleware, dispatching them to the appropriate view,
and then processing the response through middleware again before sending it to the client.
Static files (CSS, JS, images) are managed using STATIC_URL and collected with collectstatic. Media files
(uploads) are managed with MEDIA_URL and MEDIA_ROOT.
Generic views are pre-built views for common tasks like displaying lists or handling forms. They simplify
development by providing reusable components for standard operations.
Django uses migrations to apply incremental changes to the database schema. Migrations are created with
makemigrations and applied with migrate.
A Django model represents a database table and is defined as a Python class inheriting from
django.db.models.Model. Fields in the model class correspond to columns in the database table.
The render function is used to generate an HTTP response by combining a template with a context
dictionary. It simplifies rendering HTML responses in views.
Pagination is implemented using Django’s Paginator class. You create a Paginator object with the queryset
and number of items per page, then use it to get the paginated items and page number in the view.
Django prevents SQL injection by using its ORM, which automatically escapes SQL queries. Avoid using raw
SQL queries when possible, and use parameterized queries or query methods provided by the ORM.
