.__convert_rails_dates(attributes = {}) ⇒ Object

Decorates the passed in ‘attributes` so they extract the date & time values from Rails forms

Examples:

Correctly combine the date and time to a datetime string

params = { "published_on(1i)"=>"2014",
                 "published_on(2i)"=>"1",
                 "published_on(3i)"=>"1",
                 "published_on(4i)"=>"12",
                 "published_on(5i)"=>"00"
                }
MyRailsModel.new(params).published_on.iso8601
# => "2014-01-01T12:00:00+00:00"
