Question

我正在制作Django应用程序。我正在使用Django Rest Framework.models.py

class Info(models.Model):
    username = custom_fields.NotEmptyCharField(max_length=100, unique=True)
    email = models.EmailField()
    password = custom_fields.NotEmptyCharField(max_length=100)

serializers.py是

class InfoSerializer(serializers.ModelSerializer):
    created_time = serializers.DateTimeField(required=False)
    updated_time = serializers.DateTimeField(required=False)

views.py是

class InfoViews(viewsets.ModelViewSet):
    queryset = Info.objects.all()
    serializer_class = InfoSerializer

    def create(self, validated_data):
        user = get_user_model(**validated_data)
        user.set_password(validated_data['password'])
        user.save()

urls.py是

urlpatterns = [
    path('users/', views.InfoViews.as_view({
        'get': 'list',
        'post': 'create'
    })),
]

当我发布新用户数据时，

user = get_user_model(**validated_data)

TypeError：**之后的get_user_model（）参数必须是映射，而不是发生请求错误

我搜索了create() argument after ** must be a mapping, not unicode，所以我发现也许有必要的东西不在serializer.py中但我真的无法理解如何解决这个问题。我的代码出了什么问题？我应该如何解决这个问题？

在创建用户之前调用get_user_model方法获取User类：

User = get_user_model()
user = User(**validated_data)
