问题
Just was checking this episode by Ryan Bates and it seems that Rails 3.2.x has different setup.
Seems that check_box_tag requires different attributes other than Ryan puts in there. AS it writes back unexpected kEND... to <%= check_box_tag "task_ids[]", task.id %>
Any help appreciated

Your error is unrelated to your use of check_box_tag.
"unexpected kEND" indicates an unexpected end-of-file, meaning you've opened a block or other nested structure somewhere and failed to close it. Probably a do or an if with no matching end.
