Typo and acts_as_ferret rebuild_index errror

joergd · April 13, 2006, 5:57pm

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?

Thanks

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

Does Comment have the fields ‘title’ and ‘body’ defined somewhere?
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.

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)

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

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

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,
