Load a custom file in Rails

Rails generates the Lib folder by default, but there is no default load file in lib, you can configure the following code in the CONFIG/APPLICATION.RB to load the module or class defined in the Lib folder:

Config.autoload_paths + =%W (#{config.root}/lib)

Of course, this is not just a way to load Lib files, but also to load other custom folders.

Note that these custom files of the module or class name must be and file name always, such as the class name AppStore, the file name must be APP_STORE.RB, which is also rails in the Convention is greater than the configuration.
