What are the different data fetching methods in Django?

In Django, you can fetch data using methods like all(), filter(), get(), and values(). Each serves a different purpose.

Can you explain the difference between filter() and get()?

Sure! filter() returns a queryset of all matching records, while get() retrieves a single object or raises an error if not found.

When should I use values() instead of all()?

Use values() when you only need specific fields from the model, as it returns dictionaries instead of model instances.

Are there any performance considerations I should be aware of?

Yes, using select_related() and prefetch_related() can optimize performance by reducing the number of database queries.
