I have two models: Group Person I have a queryset that contains all the persons trying to join a particular group: Person.objects. filter(wantsToJo inGroup=groupD) Now, what I want to do, is display a page with a checkbo x at the side of each person that wants to join a particular group. Those checkboxes can then be checke d and then the button 'Accept to Group' is clicked. I want this to bulk add those persons to a certain group. What I fail to understand how to do is exactly the checkbox thing. I've bee n trying to extend a modelform and then make a formset out of it, but I fail at it everytime. It seems like if I want to do a formset with models I should use modelformset , but that does not all ow me to extend the form to add a checkbox. How can I do it? Here is a 10-second draft on paint of what I would like to have: So it's basically, a checkbox and a way to access the person model at the template and then a way to proccess this on the view. Thanks in advance! Edit: By the way, before someone suggests using ModelMultipleChoiceField , unless there is a way to access each of the objects inside it on the template, this will not fulfill what I need to do. As far as I know, I can't iterate over the objects of ModelMultipleChoiceField on the template. Please correct me if I'm wrong! django django-models django-forms edited Jan 25 '10 at 18:37 asked Jan 25 '10 at 17:51 Stack Overflow is a questi on and answer site for professional and enthusiast programmers.

Ifyou'renotmarriedtotheideaofusingamodelform,Iwouldjustusearegularform,withaModelMultipleChoiceField,giveitaquerysetinthe __init__thenprovidethatsamequerysettothetemplatecontext(toiterateoveratyourleisure):
#viewdefadd_to_group(request):persons=Person.objects.filter(wantsToJoinGroup=groupD)ifrequest.POST:form=PersonAddForm(persons,request.POST)ifform.is_valid():#yourhandlinglogicform=PersonAddForm(persons)context={'persons':persons,'form':form}returnrender_to_response(template,context)
#formclassPersonAddForm(forms.Form):def__init__(self,queryset,*args,**kwargs):super(PersonAddForm,self).__init__(*args,**kwargs)self.fields['persons']=forms.ModelMultipleChoiceField(queryset=queryset,widget=forms.CheckboxSelectMultiple())
