errors when using tastypie resource in view - django

Question

here is my resource:
class ImageResource(ModelResource):
album = fields.ForeignKey(AlbumResource, 'album')
upload_by = fields.ForeignKey(UserResource, 'upload_by')
class Meta:
always_return_data=True
filtering = {
"album": ('exact',),
}
queryset = Image.objects.all()
cache = SimpleCache(timeout=100)
resource_name = 'image'
authorization = ImageAuthorization()
class ImageAuthorization(Authorization):
def read_list(self, object_list, bundle):
# This assumes a ``QuerySet`` from ``ModelResource``.
userprofile = UserProfile.objects.get(user = bundle.request.user)
album = Album.objects.filter(family=userprofile.family)
return object_list.filter(album__in=album)
and when I try to use ImageResource in view like:
#csrf_exempt
def upload(request):
if request.method == 'POST':
if request.FILES:
uploadedfile = request.FILES
file = uploadedfile['item']
album = Album.objects.get(pk=int(request.POST['album_id']))
img = Image(
album = album,
name = file.name,
src=file,
upload_by = request.user,
)
# img.save()
ir = ImageResource()
uploaded_img = ir.obj_get(src=file)
print uploaded_img
return HttpResponse('True')
this will always rasie an error says
obj_get() takes exactly 2 arguments (1 given)
what's wrong with my code??? and how can I get the just uploaded image's resouce

Answer 1

Why are you trying to create instances of ImageResource? That makes no sense.
obj_get is a method for a tastypie resource, which is part of the resource flow chart. It expects a bundle object.
obj_get(self, bundle, **kwargs): ...
You do not have to create a resource on the fly for every image you upload, you don't even need to instantiate one, as the url module does this for you.
I recommend you re-read the documentation and register an ImageResource and/or AlbumResource accordingly. Those resources will pickup uploaded images or albums automatically after you register the resources to your urls module.
