Instance Method Details

#searchable(options = {}, &block) ⇒ Object

Makes a class searchable if it is not already, or adds search configuration if it is. Note that the options passed in are only used the first time this method is called for a particular class; so, search should be defined before activating any mixins that extend search configuration.

The block passed into this method is evaluated by the Sunspot.setup method. See the Sunspot documentation for complete information on the functionality provided by that method.

Options (options)

:auto_index<Boolean>

Automatically index models in Solr when they are saved. Default: true

:auto_remove<Boolean>

Automatically remove models from the Solr index when they are destroyed. Setting this option to false is not recommended (see the README).

:if<Mixed>

Only index models in Solr if the method, proc or string evaluates to true (e.g. :if => :should_index? or :if => proc { |model| model.foo > 2 }). Models that do not match the constraint will be removed from the index upon save. Multiple constraints can be specified by passing an array (e.g. :if => [:method1, :method2]).

:ignore_attribute_changes_of<Array>

Define attributes, that should not trigger a reindex of that object. Usual suspects are updated_at or counters.

:include<Mixed>

Define default ActiveRecord includes, set this to allow ActiveRecord to load required associations when indexing. See ActiveRecord’s documentation on eager-loading for examples on how to set this Default: []

:unless<Mixed>

Only index models in Solr if the method, proc or string evaluates to false (e.g. :unless => :should_not_index? or :unless => proc { |model| model.foo <= 2 }). Models that do not match the constraint will be removed from the index upon save. Multiple constraints can be specified by passing an array (e.g. :unless => [:method1, :method2]).

Example

class Post < ActiveRecord::Base
  searchable do
    text :title, :body
    string :sort_title do
      title.downcase.sub(/^(an?|the)/, '')
    end
    integer :blog_id
    time :updated_at
  end
end
