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>
