Django ModelForm具有隐藏的输入

所以我有我的TagStatus模型。我正在尝试为此制作一个ModelForm。但是,我的表单要求使用{{tag.name}}填充隐藏的输入。我一直在浏览文档,但不知道如何使标记字段成为隐藏的输入。也许ModelForm不是要走的路?

models.py:

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': ???

}

django views.py:

@login_required

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():

status_form.save()

response = simplejson.dumps({"status": "Successfully changed status"})

else:

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))

模板:

{% 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="{{ tag.name }}" />

{{ status_form.status }}

</form>

...

{% endfor %}

我将如何通过Django ModelForm进行隐藏输入,然后通过模板进行填充?

回答:

要将ModelField中的字段设为隐藏字段,请使用HiddenInput小部件。ModelForm对所有字段都使用了明智的默认小部件,你只需要在构造对象时覆盖它即可。

class TagStatusForm(forms.ModelForm):

class Meta:

model = TagStatus

widgets = {'tag': forms.HiddenInput()}
