Question

我需要选择复选框的多个初始值，这些初始值是使用小部件调整呈现的。

当我只有一个初始值时，我的代码工作得很好。但是，如果初始值超过1个，则在复选框中只会选中第一个。

forms.py

class GroupForm(forms.ModelForm):
    class Meta:
        model = Group
        fields = ('name', 'category', 'pods')

    def __init__(self, group_id, category_id, *args, **kwargs):           
        super(GroupForm, self).__init__(*args, **kwargs)
        selected_group = Group.objects.get(id=group_id) 
        self.fields['name'].initial = selected_group.name
        self.fields['category'].initial = selected_group.category.id
        self.fields['pods'].queryset = Pod.objects.filter(category=selected_group.category.id)
        associated_pods = selected_group.pod.all()  
        self.fields['pods'].initial = [pod.id for pod in associated_pods]

views.py

def GroupUpdate(request,id):
    group = get_object_or_404(Group, pk=id)
    context = {}
    group_id = group.id
    category_id = request.GET.get('category')
    context['form'] = GroupForm(group_id, category_id)
    return render(request, 'catalog/group_detail.html', context)

html文件

...
<div class="form-group">
    <label class="col-md-3 control-label">Group's Members</label>
    <div class="col-md-6">
       <div class="input-group btn-group">
           <span class="input-group-addon">
               <i class="fa fa-th-list"></i>
           </span>
           {% render_field form.pods|attr:"multiple:multiple"|attr:"data-plugin-multiselect" title="group_member" class="form-control" %}
       </div>
    </div>
</div>

我需要复选框的预选初始值才能动态呈现。当前self.fields ['pods']。initial = [associated_pods中pod的pod.id]仅勾选一个复选框，尽管关联的pod超过一个。

Answer 1

我认为我的调查取得了一些进展。这个jQuery data-plugin-multiselect以某种方式仅接受单个初始值。也许任何人都知道如何调整此jquery以使其能够接受多个初始值。

Answer 2

这可以通过将小部件添加到表单中来解决

pods = forms.ModelChoiceField(
    queryset=Pod.objects.all(),
    required=False,
    empty_label=None,
    widget=forms.SelectMultiple,
)

使用小部件调整呈现的复选框的多个首字母
