Question

i have a model

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  has_many :meetings, :dependent => :destroy do 
    def find_foreign
      Meeting.where("user_id <> ?", id)
    end
  end

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
  # attr_accessible :title, :body

end

and when i am trying to get user’s foreign meetings like that

some_user.meetings.find_foreign

i get an error

NoMethodError (undefined method `id' for []:ActiveRecord::Relation):

because self in find_foreign is an Array. How to retrive the User.id from this method ?

Answer 1

you can access self here:

def find_foreign
  Meeting.where("user_id <> ?", self.id)
end

But don’t know why you’ve written this?

some_user.meetings will already filter meetings by current user id. I’ve even no idea if block is allowed here!
