13.需求：在后台可以控制网格长和网格员在小程序端对数据的编辑权限

1.在NewCenter项目apps/user_operations/models.py中增加OnOrOff

class OnOrOff(models.Model):
    """数据操作开关"""
    wgz=models.BooleanField(default=False,verbose_name='是否开通网格长权限')
    wgy=models.BooleanField(default=False,verbose_name='是否开通网格员权限')
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "权限开关表"
        verbose_name_plural = verbose_name

执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

2.在apps/user_operations/serializers.py中：

from rest_framework import serializers
from .models import Notice,OnOrOff


class NoticeModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = Notice
        fields="__all__"


class OnOrOffModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = OnOrOff
        fields="__all__"

3.在apps/user_operations/views.py中增加查看权限类EditPowerView：

class EditPowerView(APIView):
    """查看网格长和网格员是否有权限编辑数据"""

    def get(self, request):
        powr=OnOrOff.objects.all().last()
        re=OnOrOffModelSerializer(powr)
        return Response(re.data)

4.在NewCenter/urls.py中：

from django.urls import path
from .views import GetPianQuBannerView,GetNoticeListView,UserLoginView,UpPwdView,GetCaoZuoView,UpUserInfoView,EditPowerView

urlpatterns = [
    path('getbanner/',GetPianQuBannerView.as_view()),#手机端获取banner图
    path('getnoticeclist/',GetNoticeListView.as_view()),#获取公告列表
    path('userlogin/',UserLoginView.as_view()),#小程序用户登录
    path('uppwd/',UpPwdView.as_view()),#用户修改密码
    path('getcaozuo/',GetCaoZuoView.as_view()),#获取操作数据
    path('upuserinfo/',UpUserInfoView.as_view()),#更新用户个人信息
    path('editpower/',EditPowerView.as_view()),#查看网格长和网格员是否有编辑权

]

5.在xadmin后台，增加一条记录：
