Class Method Details

.connection ⇒ Object

Attempts to retrieve a connection from the handler. If you don’t have a pool, you get to enjoy the fallback logic. If you still don’t have a connection, you get an error. It’s the circle of life.

Returns:

  • (Object) —

    The connection instance

#inspect ⇒ Object

Custom object inspection method for pretty-printing a compact, single-line summary of the object. Output examples:

#<UserNode id="26" name="Alice" age=34>   => persisted object
#<UserNode (new) name="Bob">              => object not yet saved

  # Wrap it all up in a fake-sane object string, so you can pretend your data is organized.
