Getting started

217 |

Here’s how to get rolling:

218 | 219 |
    220 |
  1. 221 |

    Use rails generate to create your models and controllers

    222 |

    To see all available options, run it without parameters.

    223 |
    2. 224 | 225 |
  2. 226 |

    Set up a default route and remove public/index.html

    227 |

    Routes are set up in config/routes.rb.

    228 |
    3. 229 | 230 |
  3. 231 |

    Create your database

    232 |

    Run rake db:create to create your database. If you're not using SQLite (the default), edit config/database.yml with your username and password.

    233 |

240 | 241 | 242 | -------------------------------------------------------------------------------- /rails_root/README: -------------------------------------------------------------------------------- 1 | == Welcome to Rails 2 | 3 | Rails is a web-application framework that includes everything needed to create 4 | database-backed web applications according to the Model-View-Control pattern. 5 | 6 | This pattern splits the view (also called the presentation) into "dumb" 7 | templates that are primarily responsible for inserting pre-built data in between 8 | HTML tags. The model contains the "smart" domain objects (such as Account, 9 | Product, Person, Post) that holds all the business logic and knows how to 10 | persist themselves to a database. The controller handles the incoming requests 11 | (such as Save New Account, Update Product, Show Post) by manipulating the model 12 | and directing data to the view. 13 | 14 | In Rails, the model is handled by what's called an object-relational mapping 15 | layer entitled Active Record. This layer allows you to present the data from 16 | database rows as objects and embellish these data objects with business logic 17 | methods. You can read more about Active Record in 18 | link:files/vendor/rails/activerecord/README.html. 19 | 20 | The controller and view are handled by the Action Pack, which handles both 21 | layers by its two parts: Action View and Action Controller. These two layers 22 | are bundled in a single package due to their heavy interdependence. This is 23 | unlike the relationship between the Active Record and Action Pack that is much 24 | more separate. Each of these packages can be used independently outside of 25 | Rails. You can read more about Action Pack in 26 | link:files/vendor/rails/actionpack/README.html. 27 | 28 | 29 | == Getting Started 30 | 31 | 1. At the command prompt, create a new Rails application: 32 | rails new myapp (where myapp is the application name) 33 | 34 | 2. Change directory to myapp and start the web server: 35 | cd myapp; rails server (run with --help for options) 36 | 37 | 3. Go to http://localhost:3000/ and you'll see: 38 | "Welcome aboard: You're riding Ruby on Rails!" 39 | 40 | 4. Follow the guidelines to start developing your application. You can find 41 | the following resources handy: 42 | 43 | * The Getting Started Guide: http://guides.rubyonrails.org/getting_started.html 44 | * Ruby on Rails Tutorial Book: http://www.railstutorial.org/ 45 | 46 | 47 | == Debugging Rails 48 | 49 | Sometimes your application goes wrong. Fortunately there are a lot of tools that 50 | will help you debug it and get it back on the rails. 51 | 52 | First area to check is the application log files. Have "tail -f" commands 53 | running on the server.log and development.log. Rails will automatically display 54 | debugging and runtime information to these files. Debugging info will also be 55 | shown in the browser on requests from 127.0.0.1. 56 | 57 | You can also log your own messages directly into the log file from your code 58 | using the Ruby logger class from inside your controllers. Example: 59 | 60 | class WeblogController < ActionController::Base 61 | def destroy 62 | @weblog = Weblog.find(params[:id]) 63 | @weblog.destroy 64 | logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!") 65 | end 66 | end 67 | 68 | The result will be a message in your log file along the lines of: 69 | 70 | Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1! 71 | 72 | More information on how to use the logger is at http://www.ruby-doc.org/core/ 73 | 74 | Also, Ruby documentation can be found at http://www.ruby-lang.org/. There are 75 | several books available online as well: 76 | 77 | * Programming Ruby: http://www.ruby-doc.org/docs/ProgrammingRuby/ (Pickaxe) 78 | * Learn to Program: http://pine.fm/LearnToProgram/ (a beginners guide) 79 | 80 | These two books will bring you up to speed on the Ruby language and also on 81 | programming in general. 82 | 83 | 84 | == Debugger 85 | 86 | Debugger support is available through the debugger command when you start your 87 | Mongrel or WEBrick server with --debugger. This means that you can break out of 88 | execution at any point in the code, investigate and change the model, and then, 89 | resume execution! You need to install ruby-debug to run the server in debugging 90 | mode. With gems, use sudo gem install ruby-debug. Example: 91 | 92 | class WeblogController < ActionController::Base 93 | def index 94 | @posts = Post.all 95 | debugger 96 | end 97 | end 98 | 99 | So the controller will accept the action, run the first line, then present you 100 | with a IRB prompt in the server window. Here you can do things like: 101 | 102 | >> @posts.inspect 103 | => "[#nil, "body"=>nil, "id"=>"1"}>, 105 | #"Rails", "body"=>"Only ten..", "id"=>"2"}>]" 107 | >> @posts.first.title = "hello from a debugger" 108 | => "hello from a debugger" 109 | 110 | ...and even better, you can examine how your runtime objects actually work: 111 | 112 | >> f = @posts.first 113 | => #nil, "body"=>nil, "id"=>"1"}> 114 | >> f. 115 | Display all 152 possibilities? (y or n) 116 | 117 | Finally, when you're ready to resume execution, you can enter "cont". 118 | 119 | 120 | == Console 121 | 122 | The console is a Ruby shell, which allows you to interact with your 123 | application's domain model. Here you'll have all parts of the application 124 | configured, just like it is when the application is running. You can inspect 125 | domain models, change values, and save to the database. Starting the script 126 | without arguments will launch it in the development environment. 127 | 128 | To start the console, run rails console from the application 129 | directory. 130 | 131 | Options: 132 | 133 | * Passing the -s, --sandbox argument will rollback any modifications 134 | made to the database. 135 | * Passing an environment name as an argument will load the corresponding 136 | environment. Example: rails console production. 137 | 138 | To reload your controllers and models after launching the console run 139 | reload! 140 | 141 | More information about irb can be found at: 142 | link:http://www.rubycentral.org/pickaxe/irb.html 143 | 144 | 145 | == dbconsole 146 | 147 | You can go to the command line of your database directly through rails 148 | dbconsole. You would be connected to the database with the credentials 149 | defined in database.yml. Starting the script without arguments will connect you 150 | to the development database. Passing an argument will connect you to a different 151 | database, like rails dbconsole production. Currently works for MySQL, 152 | PostgreSQL and SQLite 3. 153 | 154 | == Description of Contents 155 | 156 | The default directory structure of a generated Ruby on Rails application: 157 | 158 | |-- app 159 | | |-- assets 160 | | |-- images 161 | | |-- javascripts 162 | | `-- stylesheets 163 | | |-- controllers 164 | | |-- helpers 165 | | |-- mailers 166 | | |-- models 167 | | `-- views 168 | | `-- layouts 169 | |-- config 170 | | |-- environments 171 | | |-- initializers 172 | | `-- locales 173 | |-- db 174 | |-- doc 175 | |-- lib 176 | | `-- tasks 177 | |-- log 178 | |-- public 179 | |-- script 180 | |-- test 181 | | |-- fixtures 182 | | |-- functional 183 | | |-- integration 184 | | |-- performance 185 | | `-- unit 186 | |-- tmp 187 | | |-- cache 188 | | |-- pids 189 | | |-- sessions 190 | | `-- sockets 191 | `-- vendor 192 | |-- assets 193 | `-- stylesheets 194 | `-- plugins 195 | 196 | app 197 | Holds all the code that's specific to this particular application. 198 | 199 | app/assets 200 | Contains subdirectories for images, stylesheets, and JavaScript files. 201 | 202 | app/controllers 203 | Holds controllers that should be named like weblogs_controller.rb for 204 | automated URL mapping. All controllers should descend from 205 | ApplicationController which itself descends from ActionController::Base. 206 | 207 | app/models 208 | Holds models that should be named like post.rb. Models descend from 209 | ActiveRecord::Base by default. 210 | 211 | app/views 212 | Holds the template files for the view that should be named like 213 | weblogs/index.html.erb for the WeblogsController#index action. All views use 214 | eRuby syntax by default. 215 | 216 | app/views/layouts 217 | Holds the template files for layouts to be used with views. This models the 218 | common header/footer method of wrapping views. In your views, define a layout 219 | using the layout :default and create a file named default.html.erb. 220 | Inside default.html.erb, call <% yield %> to render the view using this 221 | layout. 222 | 223 | app/helpers 224 | Holds view helpers that should be named like weblogs_helper.rb. These are 225 | generated for you automatically when using generators for controllers. 226 | Helpers can be used to wrap functionality for your views into methods. 227 | 228 | config 229 | Configuration files for the Rails environment, the routing map, the database, 230 | and other dependencies. 231 | 232 | db 233 | Contains the database schema in schema.rb. db/migrate contains all the 234 | sequence of Migrations for your schema. 235 | 236 | doc 237 | This directory is where your application documentation will be stored when 238 | generated using rake doc:app 239 | 240 | lib 241 | Application specific libraries. Basically, any kind of custom code that 242 | doesn't belong under controllers, models, or helpers. This directory is in 243 | the load path. 244 | 245 | public 246 | The directory available for the web server. Also contains the dispatchers and the 247 | default HTML files. This should be set as the DOCUMENT_ROOT of your web 248 | server. 249 | 250 | script 251 | Helper scripts for automation and generation. 252 | 253 | test 254 | Unit and functional tests along with fixtures. When using the rails generate 255 | command, template test files will be generated for you and placed in this 256 | directory. 257 | 258 | vendor 259 | External libraries that the application depends on. Also includes the plugins 260 | subdirectory. If the app has frozen rails, those gems also go here, under 261 | vendor/rails/. This directory is in the load path. 262 | --------------------------------------------------------------------------------
