Post.author_id or post.author ? Rails bug?

Hi all!

I have just found something very strange.

Let’s imagine that I have posts that belong to an author.

If I do the following (the order doesn’t matter):

apost.author = Author.find(3)
apost.author_id = 2

I get a post that has both an :author_id => 2 attribute, and an
associated Author with id 3.

Then, post.save, and the author_id in the DB is 3.

I think that this is a little bit confusing… Is there something useful
in allowing to have both an author_id and an author that do not match?
