Re: BaseGenericInlineFormSet failing on Save As New in admin

Added this for my GenericInlineFormSet and things seem to work
correctly now:

class MyGenericInlineFormSet(BaseGenericInlineFormSet):
def __init__(self,*args,**kwargs):
self.save_as_new = kwargs.get('save_as_new',False)
super(MyGenericInlineFormSet,self).__init__(*args,**kwargs)

def initial_form_count(self):
if self.save_as_new:
return 0
return super(MyGenericInlineFormSet,
self).initial_form_count()

def total_form_count(self):
if self.save_as_new:
return super(MyGenericInlineFormSet,
self).initial_form_count()
return super(MyGenericInlineFormSet, self).total_form_count()

def _construct_form(self, i, **kwargs):
form = super(MyGenericInlineFormSet, self)._construct_form(i,
**kwargs)
if self.save_as_new:
# Remove the primary key from the form's data, we are only
# creating new instances
form.data[form.add_prefix(self._pk_field.name)] = None

# Remove the object id from the form's data
form.data[form.add_prefix(self.ct_fk_field_name)] = None
return form
