This pattern splits the view (also -called the presentation) into "dumb" templates that are primarily responsible -for inserting pre-built data in between HTML tags. 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. + * rmagick + * gruff (http://nubyonrails.com/pages/gruff) + * sparklines (http://nubyonrails.com/pages/sparklines) -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. +To use Selectricity in development mode, you'll need to install the +following gems: -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. - - -== Getting started - -1. Run the WEBrick servlet: ruby script/server (run with --help for options) - ...or if you have lighttpd installed: ruby script/lighttpd (it's faster) -2. Go to http://localhost:3000/ and get "Congratulations, you've put Ruby on Rails!" -3. Follow the guidelines on the "Congratulations, you've put Ruby on Rails!" screen - - -== Example for Apache conf - - - ServerName rails - DocumentRoot /path/application/public/ - ErrorLog /path/application/log/server.log - - - Options ExecCGI FollowSymLinks - AllowOverride all - Allow from all - Order allow,deny - - - -NOTE: Be sure that CGIs can be executed in that directory as well. So ExecCGI -should be on and ".cgi" should respond. All requests from 127.0.0.1 go -through CGI, so no Apache restart is necessary for changes. All other requests -go through FCGI (or mod_ruby), which requires a restart to show changes. - - -== Debugging Rails - -Have "tail -f" commands running on both the server.log, production.log, and -test.log files. 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. - - -== Breakpoints - -Breakpoint support is available through the script/breakpointer client. This -means that you can break out of execution at any point in the code, investigate -and change the model, AND then resume execution! Example: - - class WeblogController < ActionController::Base - def index - @posts = Post.find_all - breakpoint "Breaking out from the list" - end - end - -So the controller will accept the action, run the first line, then present you -with a IRB prompt in the breakpointer window. Here you can do things like: - -Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint' - - >> @posts.inspect - => "[#nil, \"body\"=>nil, \"id\"=>\"1\"}>, - #\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]" - >> @posts.first.title = "hello from a breakpoint" - => "hello from a breakpoint" - -...and even better is that 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 press CTRL-D - - -== Console - -You can interact with the domain model by starting the console through script/console. -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. -Passing an argument will specify a different environment, like console production. - - -== Description of contents - -app - Holds all the code that's specific to this particular application. + * ruby-debug -app/controllers - Holds controllers that should be named like weblog_controller.rb for - automated URL mapping. All controllers should descend from - ActionController::Base. +Also, you will need install the other applications installed first: + + * imagemagick (http://www.imagemagick.org/) + +On Ubuntu, you can install install the dependencies with: + apt-get install imagemagick libmagick9-dev ruby1.8-dev libwmf-bin + +Our server configuration uses Mongrel (installed from gems) behind an +Apache2 load balancing proxy using mod_proxy. + + +=============================================== +=== Contributors to Selectricity Include ====== +=============================================== + + * Benjamin Mako Hill + * John Dong + * Justin Sharps + +=============================================== +=== Log ======================================= +=============================================== + +07/31/07 +jlsharps: I've added a user authentication system known as +"acts_as_authenticated" to the code. The plugin is the the vendor/plugins +directory. The two most noticeable changes are the AccountController and a +redone User model. I've left the UserController in place for now, but the +AccountController works in a different manner, so am switching over to that +gradually. I saved the 5 lines or so in the old User model, overwrote +it with the authenticated generator and then recopied the old stuff back in: +has_many :elections and the name() method. The generator also creates its own +migration file, but since we are using a create.sql file I adopted the +migration file into a new users table in the create.sql file. I have yet to +delete the old table because I haven't fully combed through the code yet and +determined how many of the old attributes (such as first_name, last_name) may +need to be retained. +http://technoweenie.stikipad.com/plugins/show/Acts+as+Authenticated is the +best site for documentation regarding acts_as_authenticaed. Also, currently +it only stores the user_id in the session, but i just found a guide to help +me make it store the entire user object, so I'll do that while my battery +charges. + +08/03/07 +Handy trick: use the command 'gem_server' from a shell to create a server at +http://localhost:8008 that is an easy to navigate locally-hosted website with +all the documentation on local gems you have in a easy to read format. + +jlsharps: I added the Gruff plug-in today, which is viewable under the folder +vender/plugins/gruff. I installed it directly using the Gruff plug-in and +included controller generate utility. The version 0.1.2, which doesn't seem to +be the latest version. I've looked into it and it see and it seems that the +latest version is 0.2.8. However, I wasn't sure how including a gem w/o a plugin +would function in end-game rails so I just what I used for now. If you guys +(mako of john) know how to do it, it'd probably be better to upgrade, but it +didn't seem like the best use of my time right now. I got the plug-in here: +http://topfunky.net/svn/plugins/gruff. You can get the gruff gem v 0.2.8 by +typing "sudo gem install gruff", I believe it's also hosted on RubyForge. + +I created the GraphsController for Gruff methods to use. In Pollarize I put them +in the ApplicationContorller file, so they would be accessible to all. While +that it also an option here, it would also mean there wouldn't be much room for +playing around because everything in the Application file has to be perfect or +it seems to throw Error Code 500 (basically everything breaks). The show() +is a sample sample provided with Gruff. + +Documentation is here:http://gruff.rubyforge.org/ Alternately, if you have the +gem installed, you can use the ri command, or the above mentioned gem_server. + +If you guys want more helpful stuff here, let me know. + +====================================== +=== XML-RPC INFO == +====================================== + +The XML-RPC API is still under development, but is somewhat functional already: + +To instantiate a client in Ruby, try something like: +client=ActionWebService::Client::XmlRpc.new(SelectricityAPI,"http://localhost:3000/selectricity_service/vote") + + +Getting the results of a quickvote is quite simple: +?> client.get_quickvote_results("test") +=> # + +Casting a quickvote: +client.cast_quickvote("test",1,[[1,2]]) + +To figure out what you're voting for: +>> client.get_quickvote_candidate_map("test")=> # -app/models - Holds models that should be named like post.rb. - Most models will descend from ActiveRecord::Base. - -app/views - Holds the template files for the view that should be named like - weblog/index.rhtml for the WeblogController#index action. All views use eRuby - syntax. This directory can also be used to keep stylesheets, images, and so on - that can be symlinked to public. - -app/helpers - Holds view helpers that should be named like weblog_helper.rb. - -config - Configuration files for the Rails environment, the routing map, the database, and other dependencies. -components - Self-contained mini-applications that can bundle together controllers, models, and views. - -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. Contains subdirectories for images, stylesheets, - and javascripts. Also contains the dispatchers and the default HTML files. -script - Helper scripts for automation and generation. -test - Unit and functional tests along with fixtures. -vendor - External libraries that the application depends on. Also includes the plugins subdirectory. - This directory is in the load path.
