How to delete an object and all related objects with all imageFields insite them (photo gallery)
Here is a possible answer for the question i figured out:

Getting the list of albums in a string, in my case separated by commas 
You need to import shutil, then:
@login_required
def remove_albums(request):
    if request.is_ajax():
        if request.method == 'POST':
            #if the ajax call for delete what ok we get the list of albums to delete
            albums_list = request.REQUEST['albums_list'].rsplit(',')
            for album in albums_list:
                obj_album = Album.objects.get(id=int(album))
                #getting the directory for the images than need to be deleted
                dir_path = MEDIA_ROOT + '/images/galleries/%d' % obj_album.id
                #deleting the DB record
                obj_album.delete()
                #testing if there is a folder (there might be a record with no folder if no file was uploaded - deleting the album before uploading images)
                try:
                    #deleting the folder and all the files in it
                    shutil.rmtree(dir_path)
                except OSError:
                    pass
    return HttpResponse('')

Sorry for how the code look like, don't know why, I can't make it show correct...
Have fun and good luck :-)
I have a photo gallery with an album model (just title and date and stuff) and a photo model with a foriegn key to the album and three imageFields in it (regular, mid and thumb).
When a user delete an album i need to delete all the photos reletaed to the album (from server) then all the DB records that point to the album and then the album itself...
Couldn't find anything about this and actualy found so many answers what one say the oposite from the other.
Can any one please clarify this point, how does this is beeing done in the real world?
Thank you very much,
Erez
