django models 中的 choice 内容，如何在前端的中以下拉菜单展示出来

models.py 内容

class IdcInfo(models.Model): virtual_choice = ( (0, '否'), (1, '是'), ) idc_name = models.CharField(max_length=50, verbose_name=('机房名字'), default=u"", null=True, blank=True) is_virtual = models.IntegerField(verbose_name=("是否云主机"), choices=virtual_choice, default=0) 

views.py 内容

class IdcAddView(View): """ 添加 IDC 信息 """ def get(self, request): if request.user.is_superuser: is_virtual_list = IdcInfo.objects.all() print is_virtual_list return render(request, "assets/idcadd.html", {is_virtual_list: 'is_virtual_list'}) else: return HttpResponse("用户无权限") 

前端 html 内容

 <select class="form-control m-b" name="is_virtual"> {% for is_virtual_i in is_virtual_list %} <option>{{ is_virtual_i.get_is_virtual_choices_displa }}</option> {% endfor %} <option>option 2</option> </select>
