Django ModelFormSets vs InlineFormSets: What's the Difference?

What are the main differences between Django ModelFormSets and InlineFormSets?

Django ModelFormSets are used to manage multiple instances of a model, while InlineFormSets are specifically for managing related models in a parent-child relationship.

Can you give me an example of when to use each?

Use ModelFormSets when you want to edit multiple objects of the same model, like a list of products. Use InlineFormSets when you need to edit related objects, like adding multiple items to an order.

Are there any performance considerations I should be aware of?

Yes, InlineFormSets can be more complex and may require more queries to the database, especially with deep relationships. ModelFormSets are generally simpler and can be more efficient.

How do I implement an InlineFormSet in my Django project?

To implement an InlineFormSet, you need to define your parent and child models, create a form for the child model, and then use the InlineFormSetFactory to create the formset in your view.
