Rails - Jan 2006 - ActiveRecord callbacks not happening

Hi,

I have a model class like so:

class Candidate < ActiveRecord::Base
  validates_presence_of :name
  @@index = FerretConfig::INDEX
     
  def self.after_destroy
    puts "Ferret: after_destroy called"
    @@index.query_delete("+id:#{self.id}
+ferret_class:#{self.class.name}")
    optimize_index
  end
end

But when I delete a record, the after_destroy is never called. Nothing 
shown on logs from the puts statement. Am I missing something?


Thanks,
Vamsee.

I don''t think after_destroy should be a class method.  Try changing it
to

def after_destroy
  ...
end

One thing to watch out for is the ferret_class will be tokenized when
using query_delete.  So, ''Candidate'' will become
''candidate''.  You
might want to try creating a Boolean query with a TermQuery in it for
the ferret class.

Here is the query I use:

bq = Search::BooleanQuery.new
class_term = Ferret::Index::Term.new(''ferret_class'',
self.class.name)
bq.add_query(Ferret::Search::TermQuery.new(class_term),
Search::BooleanClause::Occur::MUST)
id_term = Index::Term.new(''id'', self.id.to_s)
bq.add_query(Search::TermQuery.new(id_term), Search::BooleanClause::Occur::MUST)

I hope that helps.

Thanks Lee, changing it to an instance method did the trick.

Vamsee.
