Ruby on Rails

Played with the code for hours and just got it to work, 20 minutes after
posting here. ruby-forum.com brought me luck, thank you :)

Here the working code:

<% if current_user.favourites.exists? :post_id => @post.id %>

So it checks the favs of the current_user in the fawvourites table and
compares the post_id ( which is the id of the already faved post) to the
current post that is displayed on the page.

Hope this helps someone else too :)
