Finding Your Way Around Rails

一、application directory

1. config.ru: configures the Rack Webserver Interface, either to create Rails Meta applications or to use Rack Middlewares in your application.

2.Gemfile: specifies the dependencies of Rails application.

3.Gemfile.lock: records the specific versions for each of Rails application's dependencies.

4.Rakefile: defines tasks to run tests, create documentation, extract the current structure of schema, and more.

5.README: general information about Rails application

A place for Application most of work take places in the app directory

A place for Tests  test directory  including fixtures that define data used by our tests.

A place for Documentation 

A place for Supporting Libraries The lib directory holds application code that doesn’t fit neatly into a model, view, or controller.

The lib directory is also a good place to put code that's shared among models, views, or controllers.

A place for Logs  development.log, test.log, and production.log. 

A place for Static Web Pages  The public directory is the external face of Rails application.

A Place for Script Wrappers 

A Place for Temporary Files 

A Place for Third-Party Code  The vendor directory is where third-party code lives.

A Place for Configuration The config directory contains files that configure Rails.
