Populate ChoiceField from database

Question

I'd like to have several fields in my form being rendered as ChoiceFields which get their content from the database.

I was thinking something like:

class SeriesForm(ModelForm):
  series = forms.ChoiceField(choices=Series.objects.all())

  class Meta:
    model = Series
    exclude = ('model', 'date_added',)

But the field series is now not appearing at all in my form. What am I missing? Thanks.

Update 2

series = forms.ModelChoiceField(queryset=Series.objects.values('series'), 
  empty_label="     ")

Answer 1

Use a ModelChoiceField instead.
