django form dropdown with all users in it

Question

I want to create a form which has a dropdown with all users in it. I tried it like this, with no luck.

class ContactFilterByClassificationForm(forms.Form):
   kam = forms.ChoiceField(choices=User.objects.all())

Answer 1

You want to use a ModelChoiceField.

class ContactFilterByClassificationForm(forms.Form):
    kam = forms.ModelChoiceField(queryset=User.objects.all())
