Re: Django 1.5.1 and formsets with more than 1000 initials

Hi Carsten,

When you create your FormSet with formset_factory, the max_number is set to the max of 1000 and max_num.
The fact that you set a bigger number of initials doesn't affect this number.
I'm not sure whether the FormSet could extends itself this number if the initial_data is larger than 1000. You probably could open a ticket about that.

Please note that a more flexible workaround would be:
> >>> ArticleFormSet = formset_factory(ArticleForm, max_num=len(MyInitials), extra=0)
