Rails plugin that scopes all finds, updates and creates to a specific column and value (country_id, company_id etc.)

In your environment.rb set this:

ActiveRecord::ScopeEverything.field = 'company_id'

In some before filter (probably after you have authenticated your user)

Thread.current['company_id'] = current_user.company.id
