12.开发newapp数据录入功能

1.不能让网格员一直随时可以修改数据，所以要设计一个开关阀，只有在开关阀开着的期间，才能进行数据修改

1.在后端项目NewCenter的user_operations/models.py中新建表格

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user_operations/adminx.py中注册：

import xadmin
from .models import Notice,OnOrOff


class NoticeAdmin(object):
    list_display = ["user","content","add_time"]
    list_filter =  ["user","content","add_time"]
    search_fields=["content"]


class OnOrOffAdmin(object):
    list_display = ["wgz","wgy","add_time"]


xadmin.site.register(Notice,NoticeAdmin)
xadmin.site.register(OnOrOff,OnOrOffAdmin)

3.在xadmin后台，增加一条记录，允许网格长和网格员权限

 2.修改潜在bug，因为后端可能要涉及到用户身份权限的修改，所以每一次打开个人中心和操作中心，都应该更新一遍用户的个人信息

1.在后端项目user_operations/views.py中：

class UpUserInfoView(APIView):
    """更新用户信息"""

    def get(self, request):
        token = request.GET.get('token')
        if token:
            user = UserProfile.objects.filter(token=token).first()
            if user:
                # 生成token
                now_time = str(int(time.time()))
                word = user.mobile + now_time
                token = hashlib.sha256(word.encode("utf-8")).hexdigest()
                # print(token)
                user.token = token
                user.save()
                re = UserProfileModelSerializer(user)
                result = {"status": "200", "data": {'info': re.data, 'token': token}}
            else:
                result = {"status": "403", "data": {'msg': '请重新登录。'}}
        else:
            result = {"status": "403", "data": {'msg': '参数不足'}}
        return HttpResponse(json.dumps(result, ensure_ascii=False), content_type="application/json,charset=utf-8")

2.在user_operations/urls.py中增加路由：

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

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
]

3.在newapp/page/me/me.vue和center/center.vue中的is_login函数中加入：

                    //更新个人数据信息开始
                    let re =await get('/user_operations/upuserinfo/',{'token':token})
                    // console.log(111,re)
                    if(re.status==200){
                        uni.setStorageSync('token' , re.data.token);
                        uni.setStorageSync('info' , re.data.info);
                    }else{
                        uni.removeStorageSync('token');
                        uni.navigateTo({url:'/pages/login/login'})
                    }
                    //更新个人数据信息结束
