Python Django Restframework密码验证不起作用

Question

一开始我也看到this的帖子，但这对我不起作用。

我有一个 Django Rest 框架项目。如果我直接通过 django 创建用户，我会收到如下错误：

但如果我有一个正常的 HTTP POST 请求，我会得到一个正常的 200 响应：

{"email": "test@test.com", "response": "successfully registered new user.", "token": "3618d0c362dd66bbb093e1234b72901f9d74a905", "username": "haha"}

有什么问题？我还尝试为密码构建自定义验证，但这并不是我真正想要的，因为它是一个很棒的 Django 功能。

api/serializers.py

class RegistrationSerializer(serializers.ModelSerializer):


    class Meta:
        model = Account
        fields = ['email', 'username', 'password', 'password2',]

    def save(self):
        account = Account(
                email = self.validated_data['email'],
                username = self.validated_data['username'],
            )
        password = self.validated_data['password']
        password2 = self.validated_data['password2']
        if password != password2:
            raise serializers.ValidationError({'password': 'Passwords must match.'})
        account.set_password(password)
        account.save()

api/views.py

@api_view(['POST', ])
def registration_view(request):

    if request.method == 'POST':
        serializer = RegistrationSerializer(data=request.data)
        data = {}
        if serializer.is_valid():
            account = serializer.save()
            data['response'] = 'successfully registered new user.'
            data['email'] = account.email
            data['username'] = account.username
            token = Token.objects.get(user = account).key
            data['token'] = token
        else:
            data = serializer.errors
            print(data)
        return Response(data)

也许你有同样的问题？

问题是，您没有密码验证。所以很简单：

api/serializers.py

from django.contrib.auth.password_validation import validate_password
...
class RegistrationSerializer(serializers.ModelSerializer):


    class Meta:
        model = Account
        fields = ['email', 'username', 'password', 'password2',]

    def save(self):
        account = Account(
                email = self.validated_data['email'],
                username = self.validated_data['username'],
            )
        password = self.validated_data['password']
        password2 = self.validated_data['password2']
        if password != password2:
            raise serializers.ValidationError({'password': 'Passwords must match.'})
->      validate_password(password)
        account.set_password(password)
        account.save()
