django-autocomplete-light的管理表单

Question

I am trying to use the django-autocomplete-light to add some nice autocomplete features to a Django Admin form. (DAL certainly seems to be the best/most popular and seems to have a lot of great features, it is a shame the docs are so poorly structured).

The autocomplete field does not get created if I create an admin form like this:

@admin.register(RaffleTicket)
class RaffleTicketAdmin(admin.ModelAdmin):
    model = RaffleTicket
    code = forms.IntegerField()
    bought_by = autocomplete_light.ModelChoiceField('PersonAutocomplete')

But it works if I create a plain ModelForm (which I never use anywhere else) and shove it directly into my ModelAdmin , like so:

class RaffleTicketForm(forms.ModelForm):
    code = forms.IntegerField()
    bought_by = autocomplete_light.ModelChoiceField('PersonAutocomplete')


@admin.register(RaffleTicket)
class RaffleTicketAdmin(admin.ModelAdmin):
    model = RaffleTicket
    form = RaffleTicketForm

Why is it so? And is there a better way (ie single class definition) to do this than what I have found?

Answer 1

The first code doesn't work because it sets form fields in the modeladmin class, which has no reason to work at all, you haven't seen that in any documentation, ever.

Did you try just this ?

@admin.register(RaffleTicket)
class RaffleTicketAdmin(admin.ModelAdmin):
    model = RaffleTicket
    form = autocomplete_light.modelform_factory(RaffleTicket)
