Django Forms: Foreign Key in Hidden Field

Question

My form:

class PlanForm(forms.ModelForm):    
    owner = forms.ModelChoiceField(label=\"\",
                                  queryset=Profile.objects.all()         


        

Answer 1

I suspect that the __unicode__ method for the Profile model instance, or the repr thereof is set to return a value other than self.id. For example, I just set this up:

# models.py
class Profile(models.Model):
    name = models.CharField('profile name', max_length=10)

    def __unicode__(self):
        return u'%d' % self.id

class Plan(models.Model):
    name = models.CharField('plan name', max_length=10)
    profile = models.ForeignKey(Profile, related_name='profiles')

    def __unicode__(self):
        return self.name


# forms.py
class PlanForm(forms.ModelForm):
    profile = forms.ModelChoiceField(queryset=Profile.objects.all(),
            widget=forms.HiddenInput())

    class Meta:
        model = Plan

# views.py
def add_plan(request):

    if request.method == 'POST':
        return HttpResponse(request.POST['profile'])


    profile = Profile.objects.all()[0]
    form = PlanForm(initial={'profile':profile})
    return render_to_response('add_plan.html',
            {
                'form':form,
            },
            context_instance=RequestContext(request))

With that, I see PlanForm.profile rendered thus in the template:
