Hello,

I am trying to convert three applications to multitenant, all of them have same structure difference is only in little functions and template designs.

All of them using cattr_accessor for setting currencies and other data, and it works perfectly

Now i added app_id as cattr_accessor to App model to use it in default_scope to implement multi-tenancy

class App < ActiveRecord::Base

  attr_accessible :active, :name

  cattr_accessor :app_id, :app_name

end

on development mode no problem, but in production values are not accessible in models.

also tried to use Thread.current, same result, on production does not work.

 

I suspect the problem is that in development the model that uses default_scope is only needed at the point that it is used, and at that point App.app_id will have been set. In production however all your models are loaded up front. Depending on when/how you set app_id, the model be setting up its default scope before you sett App.app_id. You could try using the lambda form of default_scope (personally I've always found default scope to be tricky to work with)
