Ferret talk - Apr 2006 - Typo and acts_as_ferret rebuild_index errror

Hi, I''m running the edge Typo and the latest acts_as_ferret plugin and 
ferret gems (as of 11 April).

In my Content model I put acts_as_ferret :fields => [:title, :body]

In the console, I call Content.rebuild_index to index all of my existing 
content. All the directories get created etc, but I get the following 
error back:

Loading development environment.
>> Content.rebuild_index

Has anybody got this to work before?

I''m not exactly sure why the error is about an undefined method for the
class Comment, when you run rebuild_index on Content.

1) Does Comment have the fields ''title'' and
''body'' defined somewhere?
2) Didn''t you mean Comment.rebuild_index?

Sorry - I wasn''t clear enough. Comment is defined as:

class Comment < Content

and

class Content < ActiveRecord::Base

The contents table has fields like title, body, extended etc ... so the 
Comment model will have them too then. The error isn''t particular to
the
:title field either ... if I were to have :extended as part of the 
fields list, it''ll through the same error but wrt extended.

Hi,

I could reproduce the error, but I can''t explain why it happens ;-)
I just committed a fix that rescues from the failure and indexes an
empty string for the field in question. 

It seems the errors are raised when aaf tries to index a
field that isn''t used by the particular model class, i.e. :title in a
Comment object.

Could you please try if the change fixes this for you, too ?

Greetings,
Jens

I can test it ... do I just get the latest acts_as_ferret.rb file?

That''s an old location. Try here instead (or use SVN)
http://projects.jkraemer.net/acts_as_ferret/browser/trunk/plugin/acts_as_ferret/lib/acts_as_ferret.rb?format=raw

Ok got it thanks. Tried it out. Error is gone. Return value from 
rebuild_index is false. Is that right?

According to the API false is the correct value

K great. Well - I tested it by doing searches, and my content was 
correctly indexed.

Thanks a lot for your help!

I was seeing a similar error on cases where there would be a
single row that had NULL for the value of an indexed field. Rows
before that row would index and then the exception would be
encountered and indexing would stop.

This fix also works for me.

Thanks,

Ray
