Populate ChoiceField from database

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? After trying the solution (using the `ModelChoiceField`), I'm still seeing the same issue. Here is my code: ``` series = forms.ModelChoiceField(queryset=Series.objects.values('series'), empty_label=" ") ```
