Hi folks,
I''ve working and playing with acts_as_ferret and follow this fantastic
tutorial:
http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial
When I try to implement the field storage tip, it crash. So, I try to
make it via script/console:
1. I have a simple model called Articles:
class Article < ActiveRecord::Base
acts_as_ferret :fields => [''title'']
end
2. In the console, I try this:
>> index = Article.ferret_index
=> #<Ferret::Index::Index:0x2b686dc76860 @writer=nil,
@default_input_field=:id, @qp=nil,
@dir=#<Ferret::Store::FSDirectory:0x2b686dc76748>,
@mon_entering_queue=[], @default_field=["title"], @key=:id,
@mon_count=0, @auto_flush=true, @open=true, @close_dir=true,
@id_field=:id, @mon_owner=nil, @reader=nil, @searcher=nil,
@options={:lock_retry_time=>2,
:path=>"script/../config/../config/../index/development/article",
:create_if_missing=>true, :default_field=>["title"],
:analyzer=>#<Ferret::Analysis::StandardAnalyzer:0x2b686dc75f78>,
:auto_flush=>true, :or_default=>false,
:dir=>#<Ferret::Store::FSDirectory:0x2b686dc76748>, :key=>:id,
:handle_parse_errors=>true}, @mon_waiting_queue=[]>
(it''s ok, seems to run ok! :)
>> query = "ruby"
=> "ruby">> options =""
(mmmh, just enough! Now.... )>> index.search_each(query, options) do |doc, score|
?> puts index[doc][:title]>> end
And the next and horrible message!
/usr/local/lib/site_ruby/1.8/ferret/index.rb:384: [BUG] Segmentation
fault
ruby 1.8.4 (2005-12-24) [x86_64-linux]
Woops!
Someone has the same bug!????
For more tech information:
Rails 1.2.2
Gem 0.9.2
acts_as_ferret (0.3.1)
ferret (0.11.3)
Thanks everyone!

One of the things I still need to do with Ferret is add argument checking. At the moment, if you pass a string when a hash is expected you''ll get a segfault or bus error like this. I do plan to fix this in future. Cheers, Dave -- Dave Balmain http://www.davebalmain.com/

In other way, I dont undertand why is the reason I always recieve a nil result when I use this method in the same way: $ ./script/console Loading development environment.>> article = Article.find 1=> #<Article:0x2b5120600828 @attributes={"title"=>"Ruby on Rails", "id"=>"1", "content"=>"Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Nullam tempor risus et ante. Maecenas consectetuer feugiat orci. Fusce vehicula velit id odio. Phasellus ut mauris. Aenean faucibus dolor quis nibh. Praesent convallis est id ante. In felis. "}> Ok! I put in the Article model those lines :) class Article < ActiveRecord::Base acts_as_ferret :fields => { :title=> {:store=> :yes} } end I return to console and I put the follow lines:>> index = Article.ferret_index=> #<Ferret::Index::Index:0x2b5120574120 @writer=nil, @default_input_field=:id, @qp=nil, @dir=#<Ferret::Store::FSDirectory:0x2b51205734f0>, @mon_entering_queue=[], @default_field=[:title], @key=:id, @mon_count=0, @auto_flush=true, @open=true, @close_dir=true, @id_field=:id, @mon_owner=nil, @reader=nil, @searcher=nil, @options={:lock_retry_time=>2, :path=>"script/../config/../config/../index/development/article", :create_if_missing=>true, :default_field=>[:title], :analyzer=>#<Ferret::Analysis::StandardAnalyzer:0x2b5120572460>, :auto_flush=>true, :or_default=>false, :dir=>#<Ferret::Store::FSDirectory:0x2b51205734f0>, :key=>:id, :handle_parse_errors=>true}, @mon_waiting_queue=[]> Next, I try to evaluate the search_each method>> index.search_each("Ruby",{}) do |doc, score|?> puts index[doc][:title]>> puts doc,score >> endnil 1 0.764464735984802 Great! I recieve a score value (value), the correct id value (doc), but it''s not possible to acquire the :title value with the "index[doc][:title]" expression... :( it''s always returns the nil value :( So, any way to achieve it?
