Upgrading from Tastypie 0.9.11 to 0.11 obj_get_list

Question

I tested the method on Tastypie 0.11 and seems to work ok. But in my opinion you are taking wrong and error prone approach. I prepared solution that will eliminate them.

Problem definition
You didn't defined what is your code supposed to do. Reviewing code I assume you want to have resource that returns object for currently logged user and filtered by day name. In other words you want to limit access to resource - And this is.. I think you know, authorization.

Why not obj_get_list?
You see that Tastypie obj_get_list is quite Django ORM specific and not documented well. I don't really know how to use it. I wouldn't dare to deal with it.

Solution
Let's define Authorization class for your resource:

from datetime import datetime

from tastypie.authorization import Authorization


class DriverAuthorization(Authorization):
    def read_list(self, object_list, bundle):
        todays_day_name = datetime.now().strftime('%w')
        return object_list.filter(driver__user=bundle.request.user,
                                  day=todays_day_name)

    def read_detail(self, object_list, bundle):
        todays_day_name = datetime.now().strftime('%w')
        return bundle.obj.day == todays_day_name and bundle.obj.driver.user == bundle.request.user

    def create_list(self, object_list, bundle):
        return []

    def create_detail(self, object_list, bundle):
        return False

    def update_list(self, object_list, bundle):
        return []

    def update_detail(self, object_list, bundle):
        object_before_update = object_list.get(pk=bundle.obj.pk)
        return object_before_update.driver.user == bundle.request.user

    def delete_list(self, object_list, bundle):
        return []

    def delete_detail(self, object_list, bundle):
        return False

Now attach authorization to resource:

class DriveResource(CommonModelResource):
    driver = fields.ForeignKey(DriverResource, 'driver')
    bus = fields.ForeignKey(BusResource, 'bus')
    route = fields.ForeignKey(RouteResource, 'route')

    class Meta(CommonModelResource.Meta):
        queryset = Drive.objects.all()
        allowed_methods = ['get', 'put']
        excludes = ('bus_location',)
        authorization = DriverAuthorization()
        filtering = {
            'updated': ('gt', 'gte', 'lt', 'lte', 'exact'),
            'id': ('exact',),
        }

    def dehydrate_driver(self, bundle):
        return bundle.obj.driver.person_id

    def dehydrate_bus(self, bundle):
        return bundle.obj.bus.number

    def dehydrate_route(self, bundle):
        return bundle.obj.route.id

    def hydrate_bus_location(self, bundle):
        # Guard against the method being called twice
        if not hasattr(bundle, 'geopoint_processed'):
            lon = bundle.data['bus_location'][0] / 1e6
            lat = bundle.data['bus_location'][1] / 1e6
            bundle.data['bus_location'] = Point(lon, lat)
            bundle.geopoint_processed = True
        return bundle

Benefits
1. Code now is much more clearer to read
2. You have control on what user can do or cannot do in one place.
3. No obj_get_list means no more problems.
