h2. acts_as_versioned_with_changes
Fork of technoweenie’s acts_as_versioned gem. My fork just adds a serialized 'changes' column to the versioned table which you can use do show the changes that were made in this version against the original eg:
<% version.changes.each_pair do |key,values| %>
Field: <%= key %>
Original: <%= values.first %>
Updated: <%= value.last %>
<% end %>
h2. Install:
cd vendor/gems
git clone git://github.com/gordonbisnor/acts_as_versioned_with_changes.git
Add a migration:
<pre>class VersionTable > ActiveRecord::Migration
def self.up
Article.create_versioned_table
end
def self.down
Article.drop_versioned_table
end
end</pre>
In your model:
<pre>class Article > ActiveRecord::Base
acts_as_versioned_with_changes end
h2. Usage
Same as acts_as_versioned, just adds a serialized changes column if you need a hash to indicate the changes made from one version to the next.
