Answer 1

This is what worked for me. I was trying to make a custom form . This field in the model is a charfield but I wanted a choice field generated dynamically .

The Form:

class AddRatingForRound(forms.ModelForm):

    def __init__(self, round_list, *args, **kwargs):
        super(AddRatingForRound, self).__init__(*args, **kwargs)
        self.fields['name'] = forms.ChoiceField(choices=tuple([(name, name) for name in round_list]))

    class Meta:
        model = models.RatingSheet
        fields = ('name', )

The Views:

    interview = Interview.objects.get(pk=interview_pk)
    all_rounds = interview.round_set.order_by('created_at')
    all_round_names = [rnd.name for rnd in all_rounds]
    form = forms.AddRatingForRound(all_round_names)
    return render(request, 'add_rating.html', {'form': form, 'interview': interview, 'rounds': all_rounds})

The Template:

    {% csrf_token %}
    {% if interview %}
     {{ interview }}
    {% if rounds %}
        {{ form.as_p }}
        
    {% else %}
        
No rounds found
    {% endif %}
