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?
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()}
