django-tastypie：无法访问脱水中的bundle.request（self，bundle）

我发现有人有同样的问题，但他的安慰对我不起作用： 看Django-Tastypie：如何访问 Bundle 中的 (Http)request 对象？ https://stackoverflow.com/questions/7389632

我正在尝试应用以下建议的解决方法：Django tastypie：资源在详细请求中显示与列表请求中不同 https://stackoverflow.com/questions/8242969/

在我的资源文件（api.py）中生成此代码：

class LocationResource(ModelResource):
    locationtype = fields.ForeignKey(LocationTypeResource, 'locationtype', full=False)

    class Meta:
        queryset = Location.objects.all()
        resource_name = 'location'
        excludes = ['public_anonymous', 'public_authorized','x','y','z']
        authentication = BasicAuthentication()
        authorization = DjangoAuthorization()

    def dehydrate(self, bundle):
        if bundle.request:
            if bundle.request.path: == "/api/v1/location/":
                del bundle.data['description']
            else:

                logger.debug("request availabe")
        else:
            logger.debug("request not availabe")
        return bundle

我收到错误：

如果您从 pypi 安装，您可能正在运行 Tastypie 9.10。 pypi版本中的Bundle对象确实没有请求对象 https://github.com/toastdriven/django-tastypie/blob/a9b6b23d6c3cc62ed3379089fa2d57d2d5b341ef/tastypie/bundle.py#L10.

如果您升级到 django-tastypie master 的 git 版本并使用它，问题应该可以解决。

pip uninstall django-tastypie 
pip install -e git+https://github.com/toastdriven/django-tastypie.git#egg=django-tastypie
