app
Holds all the code that's specific to this particular application.
app/assets
Contains subdirectories for images, stylesheets, and JavaScript files.
app/controllers
Holds controllers that should be named like weblogs_controller.rb for automated URL mapping. All controllers should descend from ApplicationController which itself descends from ActionController::Base.
app/models
Holds models that should be named like post.rb. Models descend from ActiveRecord::Base by default.
app/views
Holds the template files for the view that should be named like weblogs/index.html.erb for the WeblogsController#index action. All views use eRuby syntax by default.
app/views/layouts
Holds the template files for layouts to be used with views. This models the common header/footer method of wrapping views. In your views, define a layout using the <tt>layout :default</tt> and create a file named default.html.erb. Inside default.html.erb, call <% yield %> to render the view using this layout.
app/helpers
Holds view helpers that should be named like weblogs_helper.rb. These are generated for you automatically when using generators for controllers. Helpers can be used to wrap functionality for your views into methods.
config
Configuration files for the Rails environment, the routing map, the database, and other dependencies.
db
Contains the database schema in schema.rb. db/migrate contains all the sequence of Migrations for your schema.
doc
This directory is where your application documentation will be stored when generated using <tt>rake doc:app</tt>
lib
Application specific libraries. Basically, any kind of custom code that doesn't belong under controllers, models, or helpers. This directory is in the load path.
public
The directory available for the web server. Also contains the dispatchers and the default HTML files. This should be set as the DOCUMENT_ROOT of your web server.
script
Helper scripts for automation and generation.
test
Unit and functional tests along with fixtures. When using the rails generate command, template test files will be generated for you and placed in this directory.
vendor
External libraries that the application depends on. Also includes the plugins subdirectory. If the app has frozen rails, those gems also go here, under vendor/rails/. This directory is in the load path.
