Hi,
You may need to also calculate the possible options in python. Some hacky
code that might help:
class AdminRoutingInlineForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(AdminRoutingInlineForm, self).__init__(*args, **kwargs)
field1 = self.data.get('field1', '')
CHOICES = [('a', '%s any' % field1),('b', '%s blah' % field1),]
self.fields['choice_text'].choices = CHOICES
