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 that share this CharField but they each have different choices.

class MyModel(MyBaseModel):
    stuff = models.CharField('Stuff', max_length=255, default=None)

    class Meta:
        proxy = True

class MyModelAdmin(admin.ModelAdmin):
    fields = ('stuff',)
    list_display = ('stuff',)
admin.site.register(MyModel, MyModelAdmin)

For this model I want to use MY_CHOICES in MyModelAdmin.

Do I override a widget? Do I need to override the whole form?

Answer 1

from django.contrib import admin
from django import forms

class MyModel(MyBaseModel):
    stuff = models.CharField('Stuff', max_length=255, default=None)

    class Meta:
        proxy = True

class MyModelForm(forms.ModelForm):
    MY_CHOICES = (
        ('A', 'Choice A'),
        ('B', 'Choice B'),
    )

    stuff = forms.ChoiceField(choices=MY_CHOICES)

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

admin.site.register(MyModel, MyModelAdmin)
