对字典中找出最大的值

对Django查询集完成字典分析找出相对的查询集 demo仅供参考

from django.shortcuts import render, HttpResponse
from rest_framework.views import APIView
class LoginView(APIView):
  def post(self, request):
        # 获取要登录的信息
        username = request.POST.get('username')
        password = request.POST.get('password')
        if username == 'xiaowang':
            fla = User.objects.values('u_id')
            # print(type(fla))
            # flg = (type(str(fla)))
            # flg = fla[:-1]
            # print(flg)
            for item in fla:
                print(item,'-----')
                # print(max(item.values()))
            print(max(item.values(), key=lambda x: x[1]))
            obj = max(item.values(), key=lambda x: x[1])
            User.objects.create(username=username,password=password,u_id=int(obj) +1)
            return HttpResponse('ok')
