django-tastypie: Cannot access bundle.request in dehydrate(self,bundle)

问题

I found someone with the same problem, but the solation for him doesn't work with me: see Django-Tastypie: How Do You Access (Http)request object in the Bundle?

I Am trying to apply the workaround suggested in: Django tastypie: Resource show different in detailed request as in list request

resulting in this code in my resources file (api.py):

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

I get the error:

{
error_message: "'Bundle' object has no attribute 'request'",

You're probably running Tastypie 9.10 if you installed from pypi. The Bundle object in the pypi version does indeed not have a request object.

If you upgrade to the git version of django-tastypie master and use that instead the problem should be resolved.

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