Django admin choice field

Question

I have a model that has a CharField and in the admin I want to add choices to the widget. The reason for this is I\'m using a proxy model and there are a bunch of models tha

Answer 1

You need to override the form the ModelAdmin is going to use:

class MyForm(forms.ModelForm):
    stuff = forms.CharField('Stuff', max_length=255, choices=MY_CHOICES, default=None)

    class Meta:
        model = MyModel
        fields = ('stuff', 'other_field', 'another_field')


class MyModelAdmin(admin.ModelAdmin):
    fields = ('stuff',)
    list_display = ('stuff',)
    form = MyForm

If you need your choices to be dynamic, maybe you could do something similar to:

class MyForm(forms.ModelForm):
    stuff = forms.CharField('Stuff', max_length=255, choices=MY_CHOICES, default=None)

    def __init__(self, stuff_choices=(), *args, **kwargs):
        # receive a tupple/list for custom choices
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['stuff'].choices = stuff_choices

and in your ModelAdmin's __init__ define what MY_CHOICES is going to be and assign the form instance there instead:

Good luck! :)
