There is an old thread that didn't end in a resolution about preventing joins in a filter(foreign_key=None) scenario.
http://groups.google.com/group/django-users/browse_thread/thread/61ee2fb22deae326 I'd like to bring it up again and ask if there is now a way to prevent joins from a query. An example: class Blog(model.Models): editor = models.ForeignKey(User, null=True) # find all the blogs with no editors >>> Blog.objects.filter(editor=None) DEBUG:django.db.backends:(0.039) SELECT `myapp_blog`.`id` FROM `myapp_blog` LEFT OUTER JOIN `myapp_user` ON (`myapp_blog`.`editor_id` = `myapp_user`.`id`) WHERE `myapp_user`.`id` IS NULL; # Is there a way to do this query? >>> Blog.objects.filter(editor=None) DEBUG:django.db.backends:(0.039) SELECT `myapp_blog`.`id` FROM `myapp_blog` WHERE `myapp_blog`.`editor_id` IS NULL; Thanks!
