Extracting a connection out of ActiveRecord::Base
Hi I''m trying to use the Typo wordpress converter script, but it requires that the wordpress database is accessible over the connection to the Typo database.

unless connected? + multiple databases
Hello all. I am still having fun with multiple databases. In this case it is the unless connected? statement.

How to disconnect to a database????

So it is not enough to have a session check against a User

Updating multiple databases at the same time
I have an application that is load balanced. I have a master database which I update once a day. Then I push the raw mysql files to all other servers so they are the same as the master.
