Chronorails¶ ↑

Chronorails handles adding virtual attributes to your models (with suitable validations, etc) allowing you to set date and duration fields with natural language text.

gem install chronorails

For a hypothetical Rails model:

class RomanticMeeting < ActiveRecord::Base
  attr_accessible :length, :start # Integer and DateTime DB fields, respectively

  include Chronorails::ChronicAccessors
  chronic_field :start, :required => true
  chronic_duration_field :length
end

…include the accessors module, and configure Chronorails to start wrap your attributes with either Chronic or Chronic Duration virtual attributes.

Then in your form:

<%= f.text_field :chronic_start %>
<%= f.text_field :chronic_duration_length %>

…you can use the virtual attributes for your fields, entering natural language date and duration information that will be parsed into the regular fields (or will generate validation errors).

The ‘required’ option prevents setting the attributes with blank values; the ‘validates’ option controls the generation of validators (defaults to true) and the ‘accessible’ option controls the generation of Rails 3 ‘attr_accessible’ calls (also defaults to true.)
