Django forms: how to dynamically create ModelChoiceField labels
- by Henri
I would like to create dynamic labels for a forms.ModelChoiceField and I'm wondering how to do that. I have the following form class:
class ProfileForm(forms.ModelForm):
def __init__(self, data=None, ..., language_code='en', family_name_label='Family name', horoscope_label='Horoscope type', *args, **kwargs):
super(ProfileForm, self).__init__(data, *args, **kwargs)
self.fields['family_name'].label = family_name_label
.
.
self.fields['horoscope'].label = horoscope_label
self.fields['horoscope'].queryset = Horoscope.objects.all()
class Meta:
model = Profile
family_name = forms.CharField(widget=forms.TextInput(attrs={'size':'80', 'class': 'contact_form'}))
.
.
horoscope = forms.ModelChoiceField(queryset = Horoscope.objects.none(), widget=forms.RadioSelect(), empty_label=None)
The default labels are defined by the unicode function specified in the Profile definition. However the labels for the radio buttons created by the ModelChoiceField need to be created dynamically.
First I thought I could simply override ModelChoiceField as described in the Django documentation. But that creates static labels. It allows you to define any label but once the choice is made, that choice is fixed.
So I think I need to adapt add something to init like:
class ProfileForm(forms.ModelForm):
def __init__(self, data=None, ..., language_code='en', family_name_label='Family name', horoscope_label='Horoscope type', *args, **kwargs):
super(ProfileForm, self).__init__(data, *args, **kwargs)
self.fields['family_name'].label = family_name_label
.
.
self.fields['horoscope'].label = horoscope_label
self.fields['horoscope'].queryset = Horoscope.objects.all()
self.fields['horoscope'].<WHAT>??? = ???
Anyone having any idea how to handle this? Any help would be appreciated very much.
