Hi,

I want to use establish\_connection for one of my classes, but I just  
want to change the user and password, and keep the current connection  
adapter and host.

I can call ActiveRecord::Base.connection to get the adapter object,  
but I dont find how to extract the initial hash out of it.

How can I do that ?

Thx

abcs = ActiveRecord::Base.configurations  
db\_name = abcs[RAILS\_ENV][“database”]

and so on…
