I have the following four files

MODEL

class FriendshipRequest < ActiveRecord::Base

belongs_to :user

belongs_to :requested_by, :class_name => :user, :foreign_key => :requested_by_user_id

end

MIGRATION

create_table :friendship_requests do |t|

t.references :user, :null => false

t.integer :requested_by_user_id, :null => false

t.timestamps

end

CONTROLLER

def index

@user = User.find(session[:user])

@friendship_requests = FriendshipRequest.find (:all, session[:user])

end

VIEW

<% @friendship_requests.each do |friendship_request| -%>

<%= friendship_request.requested_by.inspect %>

<% end -%>

And I am getting the following error:

can't convert Symbol into String

Should I not be able to access the user through dot notation using riendship_request.requested_by?

What am I doing wrong?

Thanks!
