logger = Logger.new(STDOUT)
logger.debug ("title: #{@attr.get('title')}")
logger.debug("small_image: #{@images.search_and_convert('smallimage')}")

debug(@instance_var.pretty_inspect)

first finds where your .sock file is

second sets a symbolic link to the sock so Rails' default location for the sock is cool

mysql_config --socket

sudo ln -s  /var/run/mysqld/mysqld.sock /tmp/mysql.sock

How to manually add errors to the model
Should probably be done as part of the validate callback

self.errors.add :field_name, "isn't as it should be"

We keep error reporting off for safety reasons, but if you're baffled as to why something's not working, you can temporarily view errors by popping this into your script:

ini_set("display_errors","1");
ERROR_REPORTING(E_ALL);

And fer pete's sake remember to remove it afterwards.
