What are the differences between Django QuerySets and Q objects?

What are the differences between Django QuerySets and Q objects?

Django QuerySets are used to retrieve data from the database, while Q objects are used to construct complex queries.

Can you give me an example of how to use Q objects with QuerySets?

Sure! You can use Q objects to combine filters. For example: MyModel.objects.filter(Q(field1=value1) | Q(field2=value2)).

When should I use Q objects instead of just chaining filters?

Use Q objects when you need to perform OR operations or when you want to build dynamic queries.

Are there any performance considerations when using Q objects?

Yes, using Q objects can sometimes lead to more complex SQL queries, so it's important to test performance.
