In Django, handling static and media files efficiently is an essential aspect of web development. Static files (e.g., JavaScript, CSS, images) are files that do not change during runtime, while media files (e.g., user-uploaded files like photos, documents) are dynamic and may change or be added over time. This chapter explores how to manage both static and media files in Django, including their configuration for development and production environments.

About Lesson

What is a QuerySet?

A QuerySet is a collection of database records retrieved using Django ORM.

Chaining Filters

Filters can be chained for more specific queries:

books = Book.objects.filter(author="John Doe").filter(available=True)

Common QuerySet Methods

  • count(): Returns the number of records.
  • first()/last(): Returns the first or last record.
  • exists(): Checks if any records match the query.
