Django Trick: Using prefetch_related with Custom Querysets

Django’s ORM provides powerful tools for optimizing database queries. While select_related is well-known for fetching related objects in a single query, prefetch_related can be used for more complex relationships, especially when dealing with custom querysets for related objects.

How It Works: prefetch_related is used to optimize database access by fetching related objects in a separate query and then performing a join in Python. This is particularly useful for handling many-to-many and reverse foreign key relationships. You can also use it with custom querysets to filter and optimize the data being retrieved.

Why It’s Cool: Using prefetch_related with custom querysets allows for more efficient and flexible data retrieval. You can optimize queries and manage related objects more effectively, reducing the number of database hits and improving performance.
