Question

Ok so i have users and company and there a a join table on a many to many relationship

SO i can do

@user.companies

Can i do a scope that passes back the first company

i tied this in the user model

 scope :first_company, includes(:companies_users).where(:user_id => self.id).first

and this fails….any suggestions

Update

I have this that will work also but i was wondering if there was a equivalent scope

 def company
   self.companies.first
 end

You need to define your scope as a lambda as the context of self in a scope would be the class not the instance.

see this SO article for how to do that.
