Add associations to models/impression.rb

[sithara]

Hi
Can we add impression.rb to app/models that takes in user_id from a table other than users table? I tried adding belongs_to association but it does not work.

class SomeUser < ActiveRecord::Base
validate :user_name
end

Is there some way I can access this as Impression.first.user_name => which gives me the current user name for that particular impression

Kind Regards
Sithara

I am also trying to do this. I tried to make a model like normal but it gets ignored by rails.

class Impression < ApplicationRecord
	belongs_to :sticker, optional: true
end
