I have an Array extension method I want to use in my Rails 3 project. Where should it live?
I have a app/classes where I originally put it (array_extensions.rb), and in my config/application.rb I load the path: config.autoload_paths += %W(#{Rails.root}/app/classes). However, when I drop to rails console the extension is not loaded.
Is there a pre-definded place I should put my extension methods for Rails 3? Or, a pre-definded way to add them? I know Rails has it's own extensions methods for Array. Should I add mine to active_support/core_ext/array/conversions.rb?
What's the best practice for Rails 3?
回答1:
The better way is create your extension in lib/core_ext directory to understand easyly where is your core_ext.
After create an initializer to require this file.
回答2:
All .rb files in config/initializers are required into the environment at startup; you should be putting extensions in there.
