Problem connecting to MySQL with eRuby

I'm having a problem connecting my eRuby scripts to my MySQL database.

I've written a short test script just to work out the initial connection bugs:

<%

require 'mysql'

begin
     dbh = Mysql::new("localhost", "test", "wahssf", "amg")
rescue Mysql::Error => e
     print "Error code: #{e.errno}<br />"
     print "Error message: #{e.error}<br />"
     print "Error SQLSTATE: #{e.sqlstate}" if e.respond_to?("sqlstate")
ensure
     dbh.close if dbh
end

%>

Now, as long as I keep the connection parameters as gibberish ("test", "wahssf", "amg"), the script defaults to the Mysql::Error class and prints the following to the browser:

Error code: 1045
Error message: Access denied for user 'test'@'localhost' (using password: YES)
Error SQLSTATE: 28000

However, once I put in REAL connection values and reload the page, the script fails (for some reason?) and I get an HTTP 500 Internal Server Error.

I have absolutely no idea what the problem is. As long as the username/password combination is wrong, the script "works" but obviously doesn't connect, but as soon as I give it the proper credentials, it fai开发者_JS百科ls.

Any ideas?

Also, what's worth mentioning: When I execute this script by typing it in line by line via irb on the command prompt, it works. It only seems to be an issue in eRuby.

if message is Access denied check the username, password, host, and port!
