Instance Method Details

#acts_as_fulltextable(*attr_names) ⇒ Object

Makes a model searchable. Takes a list of fields to use to create the index. It also take an option (:check_for_changes, which defaults to true) to tell the engine wether it should check if the value of a given instance has changed before it actually updates the associated fulltext row. If option :parent_id is not nulled, it is used as the field to be used as the parent of the record, which is useful if you want to limit your queries to a scope. If option :conditions is given, it should be a string containing a ruby expression that equates to true or nil/false. Records are tested with this condition and only those that return true add/update the FullTextRow. A record returning false that is already in FullTextRow is removed.
