What are some common pitfalls when using Django ModelFormSets?

Some common pitfalls include not handling formset validation properly, failing to manage formset data correctly, and overlooking the need for custom formset logic.

Can you explain how to handle validation issues?

Certainly! You should override the is_valid() method to add custom validation logic and ensure all forms in the formset are validated.

What about managing formset data?

It's important to ensure that you correctly handle the data in the request, especially when adding or deleting forms. Use formset.save() to save all valid forms.

Are there any performance issues I should be aware of?

Yes, if you're dealing with a large number of forms, consider using pagination or limiting the number of forms displayed to improve performance.
