rails_form_backing_objects

A dumb library with a crappy name. It lets you use non-persisted objects as the targets of Rails' form_for. See this article for a description of the pattern.

I hacked this up for a project which may or may not still be using it, hence keeping it around, but this stab at the problem is probably a better bet.

class YourBackingObject < RailsFormBackingObjects::Base
  attribute(:some_attribute) #will set up attr_accessor and do nothing else
  attribute(:some_attribute) do |value|
    #apply whatever conversions you need here
  end
end

# in your controller
@form_backing_object = YourBackingObject.new

# in your view...
<%= form_for @your_backing_object do |f| %> #this just works

Oh also, it's for Ruby >= 1.9 only.

• gem install rails_form_backing_objects
