17079	"""extra"" parameter does not add any extra lines in inline formset with initial data"	mardy@…	nobody	"I have an inline formset, created with inlineformset_factory with extra=1. When editing the form, I always want to have one empty form in case the user wants to add a row.
My code looks like this:

     
{{{
        DSAFormSet = inlineformset_factory(Image, DSA, extra=1)
        if request.method == 'POST':
            dsa_formset = DSAFormSet(request.POST, instance=image, prefix='dsa')
            if dsa_formset.is_valid():
                dsa_formset.save()
        else:
            dsa_formset = DSAFormSet(instance=image, prefix='dsa')
}}}

The first time the page is loaded, we hit the ""else"" branch, and everything works fine: we get one extra blank form. But when the user fills it and resubmits the formset, no extra row is added."	Uncategorized	closed	Uncategorized	1.3	Normal	invalid	formset extra		Unreviewed	0	0	0	0	0	0
