Django ModelForm to have a hidden input

So I have my TagStatus model. I'm trying to make a ModelForm for it. However, my form requires that the hidden input be populated with the {{ }}. I've been looking through the docs and I don't know how to make the tag field a hidden input. Perhaps a ModelForm isn't the way to go?

class TagStatus(models.Model):
user = models.ForeignKey(User, null=True, unique=True)
status = models.CharField(max_length=2, choices=tag_statuses)
tag = models.ForeignKey(Tag, null=True, blank=True)

def __unicode__(self):
return self.status

def save(self, *args, **kwargs):
super(TagStatus, self).save(*args, **kwargs)

class TagStatusForm(modelForm):
class Meta:
model = TagStatus
fields = ('status','tag')
widgets = {
'select': Select,
'tag': ???


def tags(request):
all_tags = Tag.objects.all()
context = base_context(request)
if request.method == 'POST':
if 'status_check' in request.POST:
status_form = TagStatusForm(request.POST)
#if request.is_ajax():
if status_form.is_valid():
response = simplejson.dumps({"status": "Successfully changed status"})
response = simplejson.dumps({"status": "Error"})
return HttpResponse (response, mimetype='application/json')
status_form = TagStatusForm()
context['status_form'] = status_form
context['all_tags'] = all_tags
return render_to_response('tags/tags.html', context, context_instance=RequestContext(request))


{% for tag in all_tags %}
<form class="nice" id="status-form" method="POST" action="">
{% csrf_token %}
<input type="hidden" name="status_check" />
<input type='hidden' name="tag" value="{{ }}" />
{{ status_form.status }}
{% endfor %}

How would I go about making a hidden input through a django ModelForm and then populate it through the template?

To make a field in a ModelField a hidden field, use a HiddenInput widget. The ModelForm uses a sensible default widget for all the fields, you just need to override it when the object is constructed.

class TagStatusForm(forms.ModelForm):
    class Meta:
        model = TagStatus
        widgets = {'tag': forms.HiddenInput()}
