Question

I am trying to access an instance variable which is set in the controller in the model. The controller is the products controller and the model is the products model. The instance variable is a instance of another model called account.

The instance variable is @current_account

When I run the code nothing happens, I do not get an error. Does anyone know where I can find something read about access instance variables set in the controller from the model?

Thanks

You shouldn’t generally try to access the controller from the model for high-minded issues I won’t go into.

I solved a similar problem like so:

class Account < ActiveRecord::Base
  cattr_accessor :current
end

class ApplicationController < ActionController::Base
  before_filter :set_current_account
  def set_current_account
    #  set @current_account from session data here
    Account.current = @current_account
  end
end

Then just access the current account with Account.current
