Getting Started with Engines + +In this guide you will learn about engines and how they can be used to provide additional functionality to their host applications through a clean and very easy-to-use interface. You will learn the following things in this guide: + +* What are engines +* Generating an engine +* Building features for the engine +* Hooking the engine into an application +* Overriding engine functionality in the application + +endprologue. + +h3. What are engines? + +Engines can be considered miniature applications that provide functionality to their host applications. A Rails application is actually just a "supercharged" engine, with the `Rails::Application` class inheriting from `Rails::Engine`. Therefore, engines and applications share common functionality but are at the same time two separate beasts. + +h3. Generating an engine + +TODO: The engine that will be generated for this guide will be called "blorgh". It's a blogging engine that provides posts and comments and that's it. + +TODO: Describe here the process of generating an engine and what an engine comes with. + +h3. Providing engine functionality + +TODO: Brief explanation of what this engine is going to be doing and what we will have once we are done. +TODO: Generate a posts scaffold (maybe?) for the engine +TODO: Generate a comments scaffold (maybe?) for the engine + +h3. Hooking into application + +TODO: Application will provide a User foundation class which the engine hooks into through a configuration setting, configurable in the application's initializers. The engine will be mounted at the +/blog+ path in the application. + +h3. Overriding engine functionality + +TODO: Cover how to override engine functionality in the engine, such as controllers and views. +IDEA: I like Devise's +devise :controllers => { "sessions" => "sessions" }+ idea. Perhaps we could incorporate that into the guide?
