dm-mongo-adapter musings

[Jason]

Hi list,
I've been working over the past few days to move our rails (2.x) and
sinatra apps to DM 1.0 with the intention of playing around with
mongodb. The setup described here:
http://lunarlogicpolska.com/blog/2010/02/15/mysql-and-mongodb-working-together-in-kanbanery
is exactly what we're looking to implement so I went forth with hope.
However, I've run into a few issues.

1. Logging - It would be nice to be able to see what dm-mongo-adapter
is doing under the hood. How do I enable logging for this adapter?
Setting logging: true doesn't seem to be working.

2. A few patches. See http://gist.github.com/491043. In summary:
storage_exists() didn't exist so I've stubbed it for now out of
ignorance, old type code was left in, and when using active support
2.x, DateTime.now.to_time only works when the DateTime object is
already in UTC. These patches apply to ac643c82.

3. Whenever dm-mongo-adaptor executes a query, I get this in the
mongos logs: "can't find cursor: 0." I haven't seen this error with
other mongo adapters (MM, Mongoid, etc) so I don't think it's an issue
with my mongo installation. However, I can't find any reference to
this error on the internets. Any ideas?

Cheers,
-Jason

Logging is not implemented yet. If the ruby driver supports logging it
will be an easy task tho

Thanks, I'm gonna look into these!

No idea, but again - I'm gonna look into that :)

Thanks for the feedback,
