Stack Level too deep means there is some function recursing, probably forever. Looking over your code real quick I've seen the :has\_many organizations which probably leads to the recursion. When trying to get the parents, Rails will get the Parents of the Parents and so on since it is a property of the Organization so I guess it is not lazy evaluated. Maybe that helps... ---

Thanks Philipp.. I commented the has\_many :organizations sentence but it still keeps showing the errors... The issue in my code comes from this place    def self.parents > > >      @organizations = Organization.where("is\_company = ?",true) I guess it keeps asking itself about the companies which are companies within the same table... What do you think? Leo ---

yep... and "self" is one of those companies, so it keeps looping... Add a condition to exclude the current record: ``` @organizations = Organization\.where\(\["is\_company = ? AND id <> ``` ?",true, self.id]) (or whatever it takes - I'm not into Rails 3 yet... too much old 2.x stuff to do!) ---

Ignore me... I see that's a class method, so won't have an instance id... ---

I assume that the "parents" method returns all the Organizations which have child organisations? If so, you're using this method instead of a scope? Can't you do something along the lines of the pseudo-SQL below: SELECT \* FROM organisations WHERE organisations.id IN (SELECT parent\_id FROM organisations GROUP BY parent\_id) If you can get it working in SQL, you can turn it into a scope. ---
