django - Conditionally required fields across forms? -

i've got 2 forms on 1 page. if user selects option on 1 form, want make option on other form no longer required. how can that? don't think can put logic in clean method because they're separate forms.

you can in view, long set required flag false before call is_valid on second form.

class myform1(forms.form):     other_field_required = forms.booleanfield(required=false)  class myform2(forms.form):     sometimes_required = forms.charfield(required=true)  def myview(request):     form1 = myform1(request.post)     form2 = myform2(request.post)      if form1.is_valid():         if not form1.cleaned_data['other_field_required']:             form2.fields['sometimes_required'].required = false      ...         if form2.is_valid(): # form2 valid if other_field_required false 

or, add myform2 argument first form's __init__ method, can put logic in clean method.

class myform1(forms.form):     other_field_required = forms.booleanfield(required=false)      def __init__(myform2, *args, **kwargs):         super(myform1, self).__init__(*args, **kwargs)         self.form2 = form2      def clean(self):         if not self.cleaned_data['other_field_required']:             self.form2.fields['other_field_required'].required = false ...  def myview(request):     form2 = myform2(request.post)     form1 = myform1(form2, data=request.post)     ...
