How do I handle Memcached::ServerIsMarkedDead error with Rails?

Question

Hi,

In my Rails app, I changed my model's find method to search into the cache before looking into the database, but I sometime get this error:

Memcached::ServerIsMarkedDead

While waiting for Memcached server to be up again, how should I handle this error and force Rails to search into the database?

Thank you,

Kevin

You should be able to just rescue the exception and search the database in that case.

Rails.cache.fetch encapsulates this pattern in a more generic way, and you may want to look into that instead of hacking find, which is likely to bite you soon when Rails 3 comes out.
