How to register a Custom Form with Django Admin

Question

In admin_forms.py I've written the following code:

class AdminForm(forms.Form):
    category = forms.ModelChoiceField(queryset=Category.objects.all())
    question = forms.CharField(widget=forms.Textarea)
    q_active = forms.BooleanField(initial=True)
    option = forms.CharField()
    option_active = forms.BooleanField(initial=True)

I want it get registered with Django Admin, so in my admin.py, I've written

from api.admin_forms import AdminForm
class EntryAdmin(admin.ModelAdmin):
    add_form = AdminForm
    fieldsets = (
        ('Category', {
            'fields': 'category'}),
        ('Question', {'fields': ('question', 'q_active')}),
        ('Answer Option', {'fields': ('option', 'option_active')}),
        ('Selected Answer', {'fields': ('user_role', 'answer')}),
    )
admin.site.register(EntryAdmin)

Definitely, this is not how we can make it work. help please!

Solution

You should set form instead of add_form.

class EntryAdmin(admin.ModelAdmin):
    form = AdminForm
    ...

When you register your model admin, you must provide the model as the first argument:

admin.site.register(Entry, EntryAdmin)

ModelAdmin does not have an attribute add_form, so setting it has no effect. The UserAdmin has an add_form attribute, which is used when adding new users.
