Django save（）缺少1个必需的位置参数：'；自我'；

我正在使用django rest框架注册和登录。我收到这个错误save（）缺少1个必需的位置参数：“self”

这是我的serializers.py

class clientnameSerializer(serializers.ModelSerializer):
    password2 = serializers.CharField(style={'input_type': 'password'}, write_only=True)
    class Meta:
        model = clientname
        fields = ('id','username','password', 'password2' , 'email')
        ordering = ['id',]
        extra_kwargs = {
          'password': {'write_only': True}
        }
    def save(self):
      account = clientname(
        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()
      return account

如您所见，我的序列化程序中有“account.save（）”，因为当您必须重写save方法时，这一点非常重要

这是我的观点

@api_view(['POST'])
def registration_view(request):
  if request.method == 'POST':
    serializer = clientnameSerializer(data=request.data)
    data={}
    if serializer.is_valid():
      account = clientname.save()
      data['response'] = "successfully registered a new user."
      data['email'] = account.email
      data['username'] = account.username
    else:
      data = serializer.errors
    return Response(data)

这是我在尝试注册帐户时遇到的错误

Exception Value: save() missing 1 required positional argument: 'self'

这是完整的回溯

这毫无意义。您可能想要：

account = serializer.save()

---

在前端应用程序中验证password1==password2，以便只提交密码，怎么样。因为这是REST API，您可能只是想在某个时候使用这两个密码传递数据。

以下哪行会引发该错误？请也发布整个回溯。@deceze我更新我的问题，请参见和

clientname

是一个模型类吗？那么您希望

clientname.save（）

做什么呢？是的，客户端名称是一个模型类，要保存在我的数据库中，我将clientname.save（）放入数据库@deceze中，为了将数据保存到我的数据库中，我应该做些什么来解决我的问题？

account = serializer.save()
