我是django的新手。我想创建一个登录，注册API，所以我在互联网上找到一个解决方案。但它不是用户我自己的用户模型，它使用django.contrib.auth.models import AbstractUser。我不需要AbtractUser的域，所以我给它=none。这是我的模型代码:
from django.db import models
from django.contrib.postgres.fields import ArrayField
from django.contrib.postgres.fields import JSONField
from django.contrib.auth.models import AbstractUser
# Create your models here.
# class User(models.Model):
# name = models.CharField(null=False,blank=False, max_length=512)
# username = models.CharField(null=False,blank=False, max_length=512, unique=True)
# email = models.EmailField(null=False,blank=False, max_length=512, unique=True)
# password = models.CharField(null=False,blank=False, max_length=512)
# status = models.CharField(null=True,blank=True, max_length=512)
# role = models.IntegerField(null=False, blank=False, default=1)
# USERNAME_FIELD = 'username'
# REQUIRED_FIELDS = []
# def __str__(self):
# return self.username
class User(AbstractUser):
last_login = None
is_staff = None
is_superuser = None
first_name = None
last_name = None
name = models.CharField(null=False,blank=False, max_length=512)
username = models.CharField(null=False,blank=False, max_length=512, unique=True)
email = models.EmailField(null=False,blank=False, max_length=512, unique=True)
status = models.CharField(null=True,blank=True, max_length=512)
role = models.IntegerField(null=False, blank=False, default=1)
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = []
def __str__(self):
return self.username
class Category(models.Model):
title = models.TextField(null=False, blank=False)
description = models.TextField(null=False, blank=False)
class Question(models.Model):
title = models.TextField(null=False, blank=False)
description = models.TextField(null=False, blank=True)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
choices = models.JSONField(null=False, blank=False)
answer = models.TextField(null=False,blank=False)
level = models.IntegerField(null=True, blank=True)
但是我不能用我的超级用户登录到我的Django Admin。我创建了一个新的超级用户，但是我得到了一个错误TypeError: User() got an unexpected keyword argument 'is_staff'
创建超级用户命令:python manage.py createsuperuser
我不明白为什么我的模型会影响我的应用程序超级用户。谁都可以给我解释一下，给我一些解决办法。
下面是我在序列化器中的代码:
from django.contrib.postgres import fields
from rest_framework import serializers
from app.models import User, Question, Category
class RegistrationSerializer(serializers.ModelSerializer):
email = serializers.EmailField(max_length=50, min_length=6)
username = serializers.CharField(max_length=50, min_length=6)
password = serializers.CharField(max_length=150, write_only=True)
class Meta:
model = User
fields = ['id', 'name','email', 'username', 'password', 'role']
def validate(self, args):
email = args.get('email', None)
username = args.get('username', None)
if User.objects.filter(email=email).exists():
raise serializers.ValidationError({'email': ('Email already exists')})
if User.objects.filter(username=username).exists():
raise serializers.ValidationError({'username': ('Username already exists')})
return super().validate(args)
# def create(self, validated_data):
# return User.objects.create_user(**validated_data)
class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ['id', 'name', 'username', 'email', 'role']
class CategorySerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Category
fields = ['id', 'title', 'description']
class QuestionSerializer(serializers.ModelSerializer):
# category = CategorySerializer(read_only=False)
class Meta:
model = Question
fields = ['id', 'description', 'category', 'choices', 'answer', 'level']
下面是我在views中的代码:
from django.db.models import query
from django.shortcuts import render
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from rest_framework import generics
from rest_framework import viewsets
from rest_framework import serializers
from rest_framework import permissions
import uuid
from app.models import User, Category, Question
from app.serializers import UserSerializer, QuestionSerializer, CategorySerializer, RegistrationSerializer
from django.shortcuts import get_object_or_404
# Create your views here.
class RegistrationAPIView(generics.GenericAPIView):
serializer_class = RegistrationSerializer
permission_classes = (permissions.IsAuthenticated,)
def post(self, request):
serializer = self.get_serializer(data = request.data)
if(serializer.is_valid()):
serializer.save()
return Response({
"RequestId": str(uuid.uuid4()),
"Message": "User created successfully",
"User": serializer.data}, status=status.HTTP_201_CREATED
)
return Response({"Errors": serializer.errors}, status=status.HTTP_400_BAD_REQUEST)
class ListUsersAPIView(APIView):
permission_classes = (permissions.IsAuthenticated,)
def get(self, request):
listUser = User.objects.all()
info = UserSerializer(listUser, many = True)
return Response(data = info.data, status = status.HTTP_200_OK)
# def post(self, request, format=None):
# serializer = UserSerializer(data=request.data)
# if serializer.is_valid():
# serializer.save()
# return Response(serializer.data, status=status.HTTP_201_CREATED)
# return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
class DetailUsersAPIView(APIView):
permission_classes = (permissions.IsAuthenticated,)
def get(self,request, id):
try:
user = get_object_or_404(User, pk=id)
data = UserSerializer(user).data
return Response(data, status = status.HTTP_200_OK)
except:
return Response("Error",status = status.HTTP_404_NOT_FOUND)
def patch(self, request, id):
user = get_object_or_404(Users, pk=id)
serializer = UserSerializer(user, data=request.data, partial=True)
if serializer.is_valid():
serializer.save()
return Response(serializer.data)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
class CategoryViewSet(viewsets.ModelViewSet):
permission_classes = (permissions.IsAuthenticated,)
serializer_class = CategorySerializer
queryset = Category.objects.all()
class QuestionViewSet(viewsets.ModelViewSet):
permission_classes = (permissions.IsAuthenticated,)
serializer_class = QuestionSerializer
queryset = Question.objects.all()
非常感谢。
你需要定义自己的UserManager[Django-doc]来注册用户，而不需要使用is_staff,is_superuser等。该管理器用于创建用户对象。由于您已经将is_staff,is_superuser等字段设置为None，因此这些不再是模型字段。
因此，您应该实现自己的用户管理器，它将不再尝试在用户模型中设置这些字段。这意味着它看起来像:
from django.contrib.auth.models import UserManager
class CustomUserManager(UserManager):
def create_user(self, username, email=None, password=None, **extra_fields):
return self._create_user(username, email, password, **extra_fields)
def create_superuser(self, username, email=None, password=None, **extra_fields):
return self._create_user(username, email, password, **extra_fields)这个UserManager不会将is_staff和/或is_superuser添加到使用的字段中。因此，您将CutomUserManager作为objects管理器分配给用户模型:
class User(AbstractUser):
# ⋮
objects = CustomUserModel()
