NOTE: Because of the way that Ruby does constant lookup you may run into a situation where your engine controller is inheriting from the main application controller and -not your engine's application controller. Ruby will look in the ancestor chain for -constants and every class has `Object` as an ancestor, meaning that if the global -`ApplicationController` is loaded Ruby will return that and not call `const_missing` -and trigger the Rails autoloading mechanism. The best way to prevent this from +not your engine's application controller. Ruby is able to resolve the `ApplicationController` constant, and therefore the autoloading mechanism is not triggered. See the section [When Constants Aren't Missed](autoloading_and_reloading_constants.html#when-constants-aren-t-missed) of the [Autoloading and Reloading Constants](autoloading_and_reloading_constants.html) guide for further details. The best way to prevent this from happening is to use `require_dependency` to ensure that the engine's application controller is loaded. For example: |
