cannot use acts_as_ferret with remote index and single table inheritance

Reported by Jens | February 13th, 2010 @ 12:36 AM

Hi,

We're using acts_as_ferret from trunk and my searches crash while in production mode. We hunted it down and discovered that the problem is with acts_as_ferret remote index and STI models.

When the call to acts_as_ferret is processed in the base class, it is registered to the index, and then is available in the ferret server process as a valid Ruby class. When we try to use the subclass, however, it is not registered with the index (since acts_as_ferret is in the base class). The remote index call crashes like this:

[[NoMethodError]]: undefined method @[]' for #

You'll find attached a small sample rails application with acts_as_ferret installed that shows the problem in its unit tests. To run these tests, first start the server:

./script/ferret_server -e test start

then run the unit tests:

rake test:units
