Comment (by darklow):
I found a very easy solution for this problem to avoid unwanted deletion
of some inlines
You can just override delete_forms property method.
{{{
class MyInlineFormSet(BaseInlineFormSet):
@property
def deleted_forms(self):
deleted_forms = super(MyInlineFormSet, self).deleted_forms
for i, form in enumerate(deleted_forms):
if some_criteria_to_prevent_deletion:
deleted_forms.pop(i)
return deleted_forms
}}}
