Question

您好我正在尝试使用从我的视图发送的一些其他数据来呈现模型表单。但是当我尝试使用form.as_p访问表单时，它会出现以下错误：

查询集＆＃39;对象没有属性＆＃39;标签＆＃39;

的test.html

<form action="." method="post">
    {% csrf_token %}

    {{ form.as_p }}
 <div class="row">
  <div class="col-xs-5">
    {{form.tags}}

view.py

class ScheduledTestView(FormView):

serializer_class = TestShortSerializer

template_name = 'admin/scheduled_test.html'
form_class = ScheduledTestForm
initial = {'tags': Tag.objects.all()}


def form_valid(self, form):
    #some logic here

form.py

class ScheduledTestForm(forms.ModelForm):


    tags = forms.MultipleChoiceField(label='Tags', required=False)

    def __init__(self, *args, **kwargs):
        self.tags = kwargs['initial'].pop('tags', None)
        super(ScheduledTestForm, self).__init__(*args, **kwargs)
        self.fields['tags'] = self.tags

    class Meta:
        model = Test

Answer 1

您应该将字段的choices属性设置为标记，您当前正在做的是将字段的值从MultipleChoiceField更改为QuerySet

以下内容：

self.fields['tags']= self.tags

应该是：

self.fields['tags'].choices = self.tags

QuerySet对象没有属性标签Django
