Ferret talk - Oct 2007 - Offline indexing issues

If I disable ferret in my environment file and then run a cron job  
every hour to index the records that have been added/changed, do I  
enable Ferret just in the script that does the hourly indexing? Or do  
I somehow need to tell the process that runs the Ferret DRB server  
that it should start writing to the index again? Thanks in advance.

Follow Up. I have 5 mongrels and a ferret drb server running on the  
same machine. In environment.rb I disable ferret like so:

MyModel.disable_ferret

I have a script that runs every  hour that does the following:

MyModel.enable_ferret
MyModel.bulk_index all_records_created_or_changed_in_the_last_hour

Now, ClassMethods defines bulk_index as:

     def bulk_index(*ids)
       ids = ids.first if ids.size == 1 && ids.first.is_a?(Enumerable)
       aaf_index.bulk_index(ids)
     end

aaf_index is an instance of RemoteIndex that dispatches bulk_index to  
the drb server, correct? If that''s the case, then the Server class  
sends the method call to the aaf_index, which has bulk_index defined  
in ferret_extensions.rb, correct? the bulk_index method uses the  
BulkIndexer.index_records method, which checks to see if ferret is  
enbled for each record: rec.ferret_enabled?(true). Now,  if this all  
happens in the Drb server, wouldn''t ferret be disabled there as it is  
obviously using the same environment.rb file that disables ferret for  
MyModel?

Thanks in advance.

Exactly.  Since with bulk_index (and rebuild_index, too) the
ferret_enabled? check always only happens in the DRb server, calling
MyModel.enable_ferret on the client side has no effect.

I just fixed this - instance.ferret_enabled? now ignores the
class level ferret_enabled state when called by the bulk indexer (which
is also used by the rebuild_index method, so the same behaviour applies
there). 

I think the behaviour now is more useful - when you disable ferret at
the class level and then explicitly call bulk_index or rebuild_index on
this class, aaf assumes you have a good reason to do so and just does
what you say.


Cheers,
Jens
