Module: ActiveRecord::Acts::Dropdown

Defined in:
lib/rails/acts_as_dropdown/acts_as_dropdown.rb

Overview

Specify this act if you want to your model be used easily with the select form helper. By default the plugin assumes you want to use the id attribute for the option’s value and the name attribute for the option’s text.

Example:

class State < ActiveRecord::Base
  acts_as_dropdown
end

State.to_dropdown   # => [["Alabama", 1], ["Alaska", 2], ["Arizona", 3], ["California", 4], ["Colorado", 5]]

The value, text, conditions, and order can also be altered from the default configuration by using the options hash.

Example:

class State < ActiveRecord::Base
  acts_as_dropdown :text => "abbreviation", :conditions => "id < 4"
end

State.to_dropdown   # => [["AL", 1], ["AK", 2], ["AZ", 3], ["CA", 4]]

The class method to_dropdown can also alter the default class configuration using the same options hash.

Example:

class State < ActiveRecord::Base
  acts_as_dropdown :text => "abbreviation", :conditions => "id < 4"
end

State.to_dropdown :text => "name", :conditions => nil   # => [["Alabama", 1], ["Alaska", 2], ["Arizona", 3], ["California", 4], ["Colorado", 5]]
