问题描述
所以我有我的TagStatus模型。我试图为它制作一个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,我不知道如何使标签字段成为隐藏的输入。也许一个ModelForm不是要去的?
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'
'tag':???
}
django views.py:
@login_required
def标签(请求):
all_tags = Tag.objects.all()
上下文= base_context(request)
if request.method =='POST':
if'status_check'in request.POST:
status_form = TagStatusForm(request.POST)
#if request.is_ajax():
如果status_form.is_valid():
status_form.save()
response = simplejson.dumps({status:成功更改状态})
else:
response = simplejson.dumps({status:Error})
return HttpResponse(response,mimetype ='application / json')
status_form = TagStatusForm()
上下文['status_form'] = status_form
上下文['all_tags'] = all_tags
返回render_to_response('tags / tags.html',context,context_instance = RequestC ontext(request))
模板:
{%for tag in all_tags%}
....
< form class =niceid =status-formmethod =POST行动= >
{%csrf_token%}
< input type =hiddenname =status_check/>
< input type ='hidden'name =tagvalue ={{tag.name}}/>
{{status_form.status}}
< / form>
...
{%endfor%}
通过django ModelForm进行隐藏输入,然后通过模板填充它。
要在ModelField中创建一个隐藏的字段字段,使用HiddenInput小部件。 ModelForm对所有字段使用一个明智的默认窗口小部件,您只需要在构造对象时重写它。
class TagStatusForm (forms.ModelForm):
pre>
class Meta:
model = TagStatus
widgets = {'tag':forms.HiddenInput()}
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 {{ tag.name }}. 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?
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))
template:
{% 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 %}
How would I go about making a hidden input through a django ModelForm and then populate it through the template?
解决方案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()}
