How do I setup the proper permission level for this scenario with cancan?

Post has many Comments.

The post’s author can delete any comment.

The comment’s author can delete only his/her comment.

Currently I have:

authorize!(:remove_comment, @post)

and

can :remove_comment, Post, :user_id => user.id

Currently it only allows the post’s author to delete the comment but I’d like the commenter to remove his/her own comment as well.

    Couldn’t you just do something like:

    can :destroy, Comment, :user_id => user.id
