I have two tables, user & provider and I'm struggling to set up the association between them.
A simplified table structure for the two is:
CREATE TABLE users ( id integer not null, login string not null, password string not null )
CREATE TABLE providers ( id integer not null, user_id integer not null, ... )
and I've used the generater to create two modules, as follows (cut down)
class User < ActiveRecord::Base has_one :provider
def invoices_raised provider.get_invoices end
....
end
class Provider < ActiveRecord::Base has_many :invoices belongs_to :user
def get_invoices invoices.find(:all) end end
I have a controller that calls invoices_raised :
class AccountController < ApplicationController model :user
before_filter :get_invoices
def get_invoices @user = User.find(@session['user'].id)
@invoices_raised = @user.invoices_raised end
...
end
but inside the invoices_raised method I get the following error:
You have a nil object when you didn't expect it! The error occured while evaluating nil.get_invoices
I thought that using belongs_to & has_one was supposed to implicitly create a provider instance for me?
