Django模型formset查询生成额外的对象 [英] Django model formset query generates extra object

问题描述

我想创建一个确认模型的表单。我已经成功地创建了formset，但是formset创建了一个额外的确认对象。

I want to create a formset of confirmation models. I've succesfully created the formset however formset creates an extra confirmation object.

这是我的代码：

VIEW

def render_fulfillment_modal(request,template='test.html'):
    ....
    formset = modelformset_factory(Confirmation)
    form = formset(queryset=Confirmation.objects.filter(customer_order__deal = deal))

   if request.method == 'POST':
      form = formset(request.POST, request.FILES)
      if form.is_valid():
         form.save()

TEMPLATE

<form method="post" action="{% url open_fullfill_modal deal.id %}">{% csrf_token %}
      {{ form.management_form }}                  
      {% for f in form %}       
      <tr>
      <td>{{f.fullfilled}}</td>                                 
      <td>
      <p class="name">{{f.instance|confirmation_user_info}}</p>                                  
      </td>                     
      <td><input type="text" class="input-small datepicker"></td>
      <td>{{f.tracking_code}}</td>
      </tr>
      {% endfor %}

     <div class="pull-right button-box"> 
        <button type="submit" class="btn btn-primary btn-large">Save Changes</button>
     </div>

对于不在我的查询中的不相关对象的表单。我已经尝试了另一个模型，每次我得到一个额外的对象。我想这是与formets处理数据或某事的东西，我不知道。当我发布此表单时，会出现此问题。它给了我MultiValueDictKeyError，它是：

I'm getting an extra form for unrelated object which is not in my queryset. I've tried this with another models and each time I'm getting an extra object. I suppose it's something with the formsets to handle data or something, I'm not sure. The problem occurs when I post this form. It gives me MultiValueDictKeyError which is :

"Key 'form-0-id' not found in <QueryDict: {u'form-MAX_NUM_FORMS': [u''], u'form-TOTAL_FORMS': [u'3'] ... 

任何想法？

推荐答案

只要放一个 {{f.id}} before {{f.fullfilled}}

Just put a {{f.id}} before {{f.fullfilled}}

它被赋予一个隐藏的表单对于所有f，并将其传递给QueryDict请求.Post

It's given a hidden form-id for all f, and pass it to QueryDict in request.Post
