我正在尝试通过Django Rest Framework API调用使我的用户模型RESTful,以便我可以创建用户以及更新他们的配置文件.

但是,当我与用户进行特定的验证过程时,我不希望用户在创建帐户后能够更新用户名.我试图使用read_only_fields,但这似乎在POST操作中禁用了该字段,因此在创建用户对象时我无法指定用户名.

我该如何实现呢？现在存在的API的相关代码如下.

class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'password', 'email')
        write_only_fields = ('password',)

    def restore_object(self, attrs, instance=None):
        user = super(UserSerializer, self).restore_object(attrs, instance)
        user.set_password(attrs['password'])
        return user


class UserViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows users to be viewed or edited.
    """
    serializer_class = UserSerializer
    model = User

    def get_permissions(self):
        if self.request.method == 'DELETE':
            return [IsAdminUser()]
        elif self.request.method == 'POST':
            return [AllowAny()]
        else:
            return [IsStaffOrTargetUser()]

谢谢!
