Hi,
I'm working on a formset with dynamic forms. I've overloaded my form to be able
to add new values in the select field but i cannot overload the formset
constructor. Django raise exception : "__init__() takes exactly 1 argument (2
given)" - How can i change the way the formset_factory build each forms to be
able to overload each form properly for the validation ?
forms.py:
class BaseColumnFormset(BaseFormSet):
my_choices = None
def __init__(self, **kwargs):
self.my_choices = kwargs['my_choices']
del kwargs['my_choices']
super(BaseColumnFormset, self).__init__(**kwargs)
def _construct_form(self, i, **kwargs):
kwargs["my_choices"] = self.my_choices
return super(BaseColumnFormset, self)._construct_form(i,**kwargs)
class ColumnForm(forms.Form):
column = forms.ChoiceField(choices = [('A', "lol")], widget=forms.Select,
initial= 'A', label='Column')
preview = forms.CharField(widget=forms.Textarea)
def __init__(self, my_choices = None, *args, **kwargs):
super(ColumnForm, self).__init__(*args, **kwargs)
self.fields['column'].choices = my_choices
view.py:
formset_column = formset_factory(ColumnForm, formset = BaseColumnFormset)
column_formset = formset_column(request.POST)
Django raise : "__init__() takes exactly 1 argument (2 given)"
