This is a Rails extension to support dynamic, browser-side collections that work with accepts_nested_attributes_for in Rails models.
Initially, this is intended to be compatible with Rails 3.0.x and newer, using jQuery. Support for Rails 2.x and/or Prototype might or might not be added later.
To use this in your Rails 3 project (must be using jQuery), first add the following to your Gemfile…
gem 'dynested', :git => 'git@github.com:stevecj/dynested.git'
… and then execute…
rails generate dynested:javascript
Finally, you need to load the dynested Javascript file in your relevant layout file(s)…
<%= javascript_include_tag :defaults, 'dynested' %>
This is a brand new project, and is still pretty rough around the edges. The only documentation so far amounts to the comments in the /lib/dynested/form_builder_helpers.rb file, the tests in /spec/integration/dynested_spec.rb, and the usage examples in the Rails application in /spec/dummy. Specifically, under /spec/dummy/app/views, see layouts/application.html.erb and albums/_form.html.erb.
