SetNotationHelper
A library providing set notation support via a named_scope for ActiveRecord models.
Have you ever wanted to manipulate a set of resources from the database from a URL but were not sure how? Let me suggest using set notation for the ID.
GET /sounds/{1,2,3}
Install the gem and add it to your environment to add support for all your models.
To use:
sound = Sound.in_set("{1,2,3}")
Installation
sudo gem install dmichael-set-notation-helper -s http://gems.github.com
Add the gem to your environment.rb file
config.gem "dmichael-set-notation-helper", :lib => 'set_notation_helper'
Matching for sets in your routes
If you are interested in matching for sets in the routes you can do something like this
regexes = [
/%7B\s*([\d\-,(%20)*]*)\s*%7D/,
/\{\s*([\d\-,\s*]*)\s*\}/
]
regexes.each do |regex|
map.( :controller => 'sounds', :action => 'index', :id => regex, :conditions => { :method => :get }) do |r|
r.connect "/#{resource}/:id.:format"
r.connect "/#{resource}/:id"
end
end
