What are the best practices for using formsets in Django?

When using formsets in Django, it's important to keep your code DRY, validate data properly, and manage formset instances efficiently.

Can you explain how to validate data in formsets?

Sure! You can override the is_valid() method in your formset class to add custom validation logic for your formset.

What about handling formset submissions?

For handling submissions, ensure you check if the formset is valid and then save the data in a loop, handling each form individually.

Are there any performance considerations I should be aware of?

Yes, be cautious with large formsets as they can lead to performance issues. Consider using pagination or limiting the number of forms displayed.
