Dynamic Forms In Django-admin

I want to make admin add-form dynamic. I want to add few formfields depending on setting in related object. I have something like this: class ClassifiedsAdminForm(forms.ModelForm):

Solution 1:

I've managed to do it using type().

classClassifiedAdmin(admin.ModelAdmin):

 defget_form(self, request, obj=None, **kwargs):

    adminform = ClassifiedsAdminForm()
    fields = adminform.getNewFields()

    form = type('ClassifiedsAdminForm', (forms.ModelForm,), fields)

    return form

Hope it will help someone.
