Question

我有这样编码的串行器：

class InternationalSerializer(serializers.Serializer):
    """ Serializer for International
        Serializes version, which is displayed on the
        International page
    """

    overall_version = serializers.SerializerMethodField('get_overall_version',
                        read_only=True)

    def get_overall_version(self):
         # sum up all the individual country versions 
         #  to keep a unique value of the overall 
         # International version
         sum_of_versions = 0
         for key in constants.country_versions:
             sum_of_versions+=key.value()

     return sum_of_versions

〜

现在，我希望通过views.py文件显示InternationalSerializer类的'overall_version'。这是我的代码：

class International(generics.GenericAPIView):

    serializer_class = InternationalSerializer()

每当我尝试加载/ domain / international /时，我都会得到405 Method not allowed错误。这是我的urls.py包含的内容：

urlpatterns = patterns('',
    url(r'^international/$', views.International.as_view()), ...

这可能是什么问题？谢谢！

在您的情况下，您似乎并不真正需要序列化程序，因为您不会对任何对象（无论是python还是django模型对象）进行操作

因此，您可以直接返回响应，而不是使用序列化程序：

from rest_framework import generics
from rest_framework.response import Response

class International(generics.GenericAPIView):
    def get(self, request, *args, **kwargs):
        sum_of_versions = 0
        for key in constants.country_versions:
            sum_of_versions+=key.value()

        return Response({'sum_of_versions': sum_of_versions})

您获得405的原因是您没有在通用API视图类上指定get方法。
