h3. Using Action View with Rails
+For each controller there is an associated directory in the <tt>app/views</tt> directory which holds the template files that make up the views associated with that controller. These files are used to display the view that results from each controller action.
+Let's take a look at what Rails does by default when creating a new resource using the scaffold generator:
+$ rails generate scaffold post
+ [...]
+ invoke scaffold_controller
+ create app/controllers/posts_controller.rb
+ invoke erb
+ create app/views/posts
+ create app/views/posts/index.html.erb
+ create app/views/posts/edit.html.erb
+ create app/views/posts/show.html.erb
+ create app/views/posts/new.html.erb
+ create app/views/posts/_form.html.erb
+ [...]
+There is a naming convention for views in Rails. Typically, the views share their name with the associated controller action, as you can see above.
+For example, the index controller action of the <tt>posts_controller.rb</tt> will use the <tt>index.html.erb</tt> view file in the <tt>app/views/posts</tt> directory.
+The complete HTML returned to the client is composed of a combination of this ERB file, a layout template that wraps it, and all the partials that the view may reference. Later on this guide you can find a more detailed documentation of each one of this three components.
