Subject: Major update of Selectricity to work with Rails 2.2.2 from 1.2!
X-Git-Url: https://projects.mako.cc/source/selectricity-live/commitdiff_plain/ad088c1324d08a65f6f5336bedf7a88a8a8950e7?ds=sidebyside

Major update of Selectricity to work with Rails 2.2.2 from 1.2!

This included a large number of changes:

- removal of randarray.rb (features are not in the new version or ruby)
- removal of sparklines plugin and replacement with gemified version of
  sparklines and sparklines_generator
- addition of act_as_list plugin which is no longer in rails
- disabling of all API code because action_web_service is deprecated in
  favor of active_resource (!!!!)
- large number of miscellaneous updates to do the new rails 2ish

I've commented out the new features in the views (i.e., embedded) as
this is going to replace the LIVE version of Selectricity. We should
then test this well, slowly enable the new features, and get the tests i
old_api_code back work with an active_resource interface.

+ActsAsList
+==========
+
+This acts_as extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a +position+ column defined as an integer on the mapped database table.
+
+
+Example
+=======
+
+  class TodoList < ActiveRecord::Base
+    has_many :todo_items, :order => "position"
+  end
+
+  class TodoItem < ActiveRecord::Base
+    belongs_to :todo_list
+    acts_as_list :scope => :todo_list
+  end
+
+  todo_list.first.move_to_bottom
+  todo_list.last.move_higher

-=begin rdoc
-
-A library for generating small unmarked graphs (sparklines).
-
-Can be used to write an image to a file or make a web service with Rails or other Ruby CGI apps.
-
-Idea and much of the outline for the source lifted directly from {Joe Gregorio's Python Sparklines web service script}[http://bitworking.org/projects/sparklines].
-
-Requires the RMagick image library.
-
-==Authors
-
-{Dan Nugent}[mailto:nugend@gmail.com] Original port from Python Sparklines library.
-
-{Geoffrey Grosenbach}[mailto:boss@topfunky.com] -- http://nubyonrails.topfunky.com 
--- Conversion to module and further maintenance.
-
-==General Usage and Defaults
-
-To use in a script:
-
-	require 'rubygems'
-	require 'sparklines'
-	Sparklines.plot([1,25,33,46,89,90,85,77,42], 
-	                :type => 'discrete', 
-	                :height => 20)
-
-An image blob will be returned which you can print, write to STDOUT, etc.
-
-For use with Ruby on Rails, see the sparklines plugin:
-
-  http://nubyonrails.com/pages/sparklines
-
-In your view, call it like this:
-
-  <%= sparkline_tag [1,2,3,4,5,6] %>
-
-Or specify details:
-
-  <%= sparkline_tag [1,2,3,4,5,6], 
-                    :type => 'discrete', 
-                    :height => 10, 
-                    :upper => 80, 
-                    :above_color => 'green', 
-                    :below_color => 'blue' %>
-
-Graph types:
-
- area
- discrete
- pie
- smooth
- bar
- whisker
-
-General Defaults:
-
- :type              => 'smooth'
- :height            => 14px
- :upper             => 50
- :above_color       => 'red'
- :below_color       => 'grey'
- :background_color  => 'white'
- :line_color        => 'lightgrey'
