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_requireddef 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()}
