Hey Adi your answer saved me lots of work, but i want to elaborate on it, i
had this use case but i didnt have to subclass the field all i did was
defined a new label_from_instance
def Option_with_specie(self):
return mark_safe("<option data-specie='%s' value='%s'> %s
</option>"%(self.species.name, self.pk, self.name))
And then on the forms init:
class PetForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(PetForm, self).__init__(*args, **kwargs)
if 'instance' in kwargs:
self.fields['breed'].label_from_instance = Option_with_specie
So now i customized the select field outputted by the foreing key, thanks
to you Adi for finding just the right method to override.
