Question

我试图返回多个具有相同名称的表单元素，但是我只获得最后一个元素而不是所有元素。在我的视图中它可以工作并显示所有元素，一旦我点击提交仅返回最后一个元素（在这种情况下为3次）。那是为什么？

forms.py：

class GroupAddForm(forms.ModelForm):
    email = forms.EmailField(label='' ,widget=forms.HiddenInput(attrs={'class': 'form-control'}))
    page_name = forms.CharField(label='' ,widget=forms.HiddenInput(attrs={'rows': '4', 'class': 'form-control'}))
    page_street =  forms.CharField(label='' ,widget=forms.HiddenInput(attrs={'rows': '4', 'class': 'form-control'}))
    add_button = forms.BooleanField(label='', required=False, widget=forms.CheckboxInput(attrs={'rows': '4', 'class': 'form-control'}))

    class Meta: 
        model = GroupManagement
        fields = ['email', 'page_name', 'page_street', 'add_button']

View.py

for items in locationdata:
        show_name.append(items[1])
        show_street.append(items[2])
        name = items[1]
        street = items[2]
        form = GroupAddForm(request.POST or None, initial={"page_name": name, "page_street": street, "email": email})
        forms.append(form)

    for item in forms:
        if item.is_valid():
            email = item.cleaned_data.get("email")
            page_name = item.cleaned_data.get("page_name")
            page_street = item.cleaned_data.get("page_street")
            add_button = item.cleaned_data.get("add_button")    
            if add_button == true: 
    //// do stuff



    context = {
    'names': names,
    'street': street,
    'group_name_form': group_name_form,
    'locationdata': locationdata,
    'forms': forms,
    }

模板：

      <div class="modal-body">
       <div class="col-md-12">
         <form method="POST" action=""> {% csrf_token %}
                                                        {{group_name_form.as_p}}

<div class="col-md-6 pull-left">
   {% for items in names %}

   <p style="text-align:left;"> {{items.0}}  {{items.1}} </p>

      {% endfor %}
     </div>
   <div class="col-md-6">
    {% for items in forms %}
    {{items.as_p}} 

       {% endfor %}
    </div>
 </div>

      <input type="submit" class="btn btn-success" value="Gruppe erstellen"></form>
   </div>

使用同一表单类的多个实例的正确方法是使用formsets。

附加表单元素仅返回一组数据
