solutions_sidekiq    | Being able to do this is deprecated. Autoloading during initialization is going
solutions_sidekiq    | to be an error condition in future versions of Rails.
solutions_sidekiq    |
solutions_sidekiq    | Reloading does not reboot the application, and therefore code executed during
solutions_sidekiq    | initialization does not run again. So, if you reload EmberCliRailsAssetsHelper, for example,
solutions_sidekiq    | the expected changes won't be reflected in that stale Module object.
solutions_sidekiq    |
solutions_sidekiq    | These autoloaded constants have been unloaded.
solutions_sidekiq    |
solutions_sidekiq    | In order to autoload safely at boot time, please wrap your code in a reloader
solutions_sidekiq    | callback this way:
solutions_sidekiq    |
solutions_sidekiq    |     Rails.application.reloader.to_prepare do
solutions_sidekiq    |       # Autoload classes and modules needed at boot time here.
solutions_sidekiq    |     end
solutions_sidekiq    |
solutions_sidekiq    | That block runs when the application boots, and every time there is a reload.
solutions_sidekiq    | For historical reasons, it may run twice, so it has to be idempotent.
solutions_sidekiq    |
solutions_sidekiq    | Check the "Autoloading and Reloading Constants" guide to learn more about how
solutions_sidekiq    | Rails autoloads and reloads.
