-== Welcome to Rails
+===============================================
+=== Depedendencies ============================
+===============================================
+
+To use Selectricity, you'll need to install the following gems in
+addition to rails and its dependencies:

 
 

-Rails is a web-application and persistence framework that includes everything
-needed to create database-backed web-applications according to the
-Model-View-Control pattern of separation. 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.
-
-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.
+ * rmagick
+ * gruff (http://nubyonrails.com/pages/gruff)
+ * sparklines (http://nubyonrails.com/pages/sparklines)

 
 

-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.
+To use Selectricity in development mode, you'll need to install the
+following gems:

 
 

+ * ruby-debug

 
 

-== Getting started
+Also, you will need install the other applications installed first:

 
 

-1. Start the web server: <tt>ruby script/server</tt> (run with --help for options)
-2. Go to http://localhost:3000/ and get "Welcome aboard: You’re riding the Rails!"
-3. Follow the guidelines to start developing your application
+ * 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

 
 

-== Web servers

 
 

-Rails uses the built-in web server in Ruby called WEBrick by default, so you don't
-have to install or configure anything to play around. 
+===============================================
+=== Contributors to Selectricity Include ======
+===============================================

 
 

-If you have lighttpd installed, though, it'll be used instead when running script/server.
-It's considerably faster than WEBrick and suited for production use, but requires additional
-installation and currently only works well on OS X/Unix (Windows users are encouraged
-to start with WEBrick). We recommend version 1.4.11 and higher. You can download it from
-http://www.lighttpd.net.
+ * Benjamin Mako Hill <mako@atdot.cc>
+ * John Dong          <jdong@ubuntu.com>
+ * Justin Sharps      <jlsharps@mit.edu>

 
 

-If you want something that's halfway between WEBrick and lighttpd, we heartily recommend
-Mongrel. It's a Ruby-based web server with a C-component (so it requires compilation) that
-also works very well with Windows. See more at http://mongrel.rubyforge.org/.
+===============================================
+=== Log =======================================
+===============================================

 
 

-But of course its also possible to run Rails with the premiere open source web server Apache.
-To get decent performance, though, you'll need to install FastCGI. For Apache 1.3, you want
-to use mod_fastcgi. For Apache 2.0+, you want to use mod_fcgid.

+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.

 
 

-See http://wiki.rubyonrails.com/rails/pages/FastCGI for more information on FastCGI.
+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.

 
 

-== Example for Apache conf
+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. 

 
 

-  <VirtualHost *:80>
-    ServerName rails
-    DocumentRoot /path/application/public/
-    ErrorLog /path/application/log/server.log
-  
-    <Directory /path/application/public/>
-      Options ExecCGI FollowSymLinks
-      AllowOverride all
-      Allow from all
-      Order allow,deny
-    </Directory>
-  </VirtualHost>
+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. 

 
 

-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.
+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.

 
 

-== Debugging Rails
+======================================
+=== XML-RPC INFO                    ==
+======================================

 
 

-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.
+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")

 
 

-== 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:
+Getting the results of a quickvote is quite simple:
+?> client.get_quickvote_results("test")
+=> #<VoteResultStruct:0x336f92c @approval_winners=[1, 2], @borda_winners=[1], @plurality_winners=[1], @ssd_winners=[1], @errors=[], @condorcet_winners=[1]>

 
 

-  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:
+Casting a quickvote:
+client.cast_quickvote("test",1,[[1,2]])

 
 

-Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint'
+To figure out what you're voting for:
+>> client.get_quickvote_candidate_map("test")=> #<CandidateMap:0x335bbc0 @errors=[], @candidate_names=["test", "test2"], @candidate_ids=[1, 2]>

 
 

-  >> @posts.inspect
-  => "[#<Post:0x14a6be8 @attributes={\"title\"=>nil, \"body\"=>nil, \"id\"=>\"1\"}>, 
-       #<Post:0x14a6620 @attributes={\"title\"=>\"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 
-  => #<Post:0x13630c4 @attributes={"title"=>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 <tt>script/console production</tt>.
-
-To reload your controllers and models after launching the console run <tt>reload!</tt>
