The model contains the "smart" domain objects (such as Account, -Product, Person, Post) that holds all the business logic and knows how to -persist themselves to a database. The controller handles the incoming requests -(such as Save New Account, Update Product, Show Post) by manipulating the model -and directing data to the view. -In Rails, the model is handled by what's called an object-relational mapping -layer entitled Active Record. This layer allows you to present the data from -database rows as objects and embellish these data objects with business logic -methods. You can read more about Active Record in -link:files/vendor/rails/activerecord/README.html. +== But How? -The controller and view are handled by the Action Pack, which handles both -layers by its two parts: Action View and Action Controller. These two layers -are bundled in a single package due to their heavy interdependence. This is -unlike the relationship between the Active Record and Action Pack that is much -more separate. Each of these packages can be used independently outside of -Rails. You can read more about Action Pack in -link:files/vendor/rails/actionpack/README.html. +The loving individuals of Mechnical Turk and the Rails Turk integration gem, {Turkee}[https://www.github.com/aantix/turkee/] -== Getting Started +== Demo -1. At the command prompt, create a new Rails application: - rails new myapp (where myapp is the application name) +* Create your config/database.yml -2. Change directory to myapp and start the web server: - cd myapp; rails server (run with --help for options) +* Run rake db:migrate -3. Go to http://localhost:3000/ and you'll see: - "Welcome aboard: You're riding Ruby on Rails!" +* Run rake db:seed -4. Follow the guidelines to start developing your application. You can find -the following resources handy: +* Start the server with 'rails s' -* The Getting Started Guide: http://guides.rubyonrails.org/getting_started.html -* Ruby on Rails Tutorial Book: http://www.railstutorial.org/ +* Go to {http://localhost:3000}[http://localhost:3000] +There you will see the form that is presented to the Turkers. That is all I have thus far. -== Debugging Rails -Sometimes your application goes wrong. Fortunately there are a lot of tools that -will help you debug it and get it back on the rails. +== Copyright -First area to check is the application log files. Have "tail -f" commands -running on the server.log and development.log. Rails will automatically display -debugging and runtime information to these files. Debugging info will also be -shown in the browser on requests from 127.0.0.1. +Copyright (c) 2012 Jim Jones. See LICENSE for details. -You can also log your own messages directly into the log file from your code -using the Ruby logger class from inside your controllers. Example: - class WeblogController < ActionController::Base - def destroy - @weblog = Weblog.find(params[:id]) - @weblog.destroy - logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!") - end - end -The result will be a message in your log file along the lines of: - - Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1! - -More information on how to use the logger is at http://www.ruby-doc.org/core/ - -Also, Ruby documentation can be found at http://www.ruby-lang.org/. There are -several books available online as well: - -* Programming Ruby: http://www.ruby-doc.org/docs/ProgrammingRuby/ (Pickaxe) -* Learn to Program: http://pine.fm/LearnToProgram/ (a beginners guide) - -These two books will bring you up to speed on the Ruby language and also on -programming in general. - - -== Debugger - -Debugger support is available through the debugger command when you start your -Mongrel or WEBrick server with --debugger. This means that you can break out of -execution at any point in the code, investigate and change the model, and then, -resume execution! You need to install ruby-debug to run the server in debugging -mode. With gems, use sudo gem install ruby-debug. Example: - - class WeblogController < ActionController::Base - def index - @posts = Post.all - debugger - end - end - -So the controller will accept the action, run the first line, then present you -with a IRB prompt in the server window. Here you can do things like: - - >> @posts.inspect - => "[#nil, "body"=>nil, "id"=>"1"}>, - #"Rails", "body"=>"Only ten..", "id"=>"2"}>]" - >> @posts.first.title = "hello from a debugger" - => "hello from a debugger" - -...and even better, you can examine how your runtime objects actually work: - - >> f = @posts.first - => #nil, "body"=>nil, "id"=>"1"}> - >> f. - Display all 152 possibilities? (y or n) - -Finally, when you're ready to resume execution, you can enter "cont". - - -== Console - -The console is a Ruby shell, which allows you to interact with your -application's domain model. Here you'll have all parts of the application -configured, just like it is when the application is running. You can inspect -domain models, change values, and save to the database. Starting the script -without arguments will launch it in the development environment. - -To start the console, run rails console from the application -directory. - -Options: - -* Passing the -s, --sandbox argument will rollback any modifications - made to the database. -* Passing an environment name as an argument will load the corresponding - environment. Example: rails console production. - -To reload your controllers and models after launching the console run -reload! - -More information about irb can be found at: -link:http://www.rubycentral.org/pickaxe/irb.html - - -== dbconsole - -You can go to the command line of your database directly through rails -dbconsole. You would be connected to the database with the credentials -defined in database.yml. Starting the script without arguments will connect you -to the development database. Passing an argument will connect you to a different -database, like rails dbconsole production. Currently works for MySQL, -PostgreSQL and SQLite 3. - -== Description of Contents - -The default directory structure of a generated Ruby on Rails application: - - |-- app - | |-- assets - | |-- images - | |-- javascripts - | `-- stylesheets - | |-- controllers - | |-- helpers - | |-- mailers - | |-- models - | `-- views - | `-- layouts - |-- config - | |-- environments - | |-- initializers - | `-- locales - |-- db - |-- doc - |-- lib - | `-- tasks - |-- log - |-- public - |-- script - |-- test - | |-- fixtures - | |-- functional - | |-- integration - | |-- performance - | `-- unit - |-- tmp - | |-- cache - | |-- pids - | |-- sessions - | `-- sockets - `-- vendor - |-- assets - `-- stylesheets - `-- plugins - -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 layout :default 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 rake doc:app - -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.
