Django populate a form.ChoiceField field from a queryset and relate the choice back to the model object

Question

I have a simple form:

class SubmissionQuickReplyForm(forms.Form):
    comment_text = forms.CharField(label=\'\', required=False, widget=forms.Textarea(attrs={\'r         


        

Answer 1

For ChoiceField you can use

    choice = forms.ChoiceField(choices=[
    (choice.pk, choice) for choice in MyChoices.objects.all()])

Answer 2

You can use ModelChoiceField instead.

choice = forms.ModelChoiceField(queryset=MyChoices.objects.all())

And you can get by simply call cleaned_data like this.

if request.method == "POST":
    form = SubmissionQuickReplyForm(request.POST)
    if form.is_valid():
        ch = form.cleaned_data.get('choice')
