Relating 3 models.

Hi,

I have 3 models.

Users:

id | name | email

Posts:

id | posted_user_id | body

posts_rating

id | post_id | rating

Firstly I'm fetching posts_rating table data.

Using relationship I have related posts_rating table with Posts table. I also want to fetch the user of the post. How can I do that ?

I mean how to relate posts_rating->Posts->Users table ?

Thanks!
