Beginner: Creating a form with variable number of checkboxes

[T Kwn]

I'm creating a page where the user can add other users to a group. I am able to dynamically fetch all users and list them on a template with checkboxes. I'm getting stuck creating a form for them however.

I read this post (among others)

http://stackoverflow.com/questions/19947538/django-form-with-unknown-number-of-checkbox-fields-and-multiple-actions

I don't understand what should be used to define "choices" in this example. He says fill it with a queryset but which one?

choices = queryset_of_valid_choices,

Would that be something like objects_list.all()?


Currently my form is defined as this:

class UpdateGroup(forms.Form):
    non_member_checkboxes = forms.MultipleChoiceField(
        widget  = forms.CheckboxSelectMultiple,
    )

I know it's missing something because the form.is_valid is always False.

Hi,

The forms.ModelMultipleChoiceField might help you out here.

class UpdateGroup(forms.Form):
    non_member_checkboxes = forms.ModelMultipleChoiceField(
        queryset=User.objects.all(),
        widget=forms.CheckboxSelectMultiple,
    )
