Scope with join on :has_many :through association

Question

class Users < ActiveRecord::Base
  has_many :meetings, :through => :meeting_participations
  has_many :meeting_participations
end

class Meetings < ActiveRe         


        

Answer 1

Here's a one liner:

Meeting.joins(:meeting_participations).where(meeting_participation: { hidden: false, user_id: current_user.id })

This is great because you can make a scope out of it, a function out of it, or simply call it anywhere. You can also add any more restrictions you want to the hash.
