hi.
i’ve an application which is using a local mysql server (on
localhost). i then moved the mysql server to another machine (remote
host) and changed accordingly the “database.yml” file.
when i launch webrick from the “localhost”, it can connect to the
database but as soon as i call a controller of the application (for
example “http://remotehost/indicator/list”) i get the following error
(please, see below).
i installed on the remote machine (a win2003 box) both ruby (one-click
installer) and ruby for apache (because of the mysql.so file). the
fact is that it seems activerecord is still getting the mysql host as
“localhost” instead of the remote host address.
could it be a cache issue? any ideas? many thanks in advance.
