Instance Method Details

#connect(&bl) ⇒ Object

Connects to the database, starts a transaction if required, then yields the block with the connection object.

The connection is kept under an instance variable and can be later obtained through the ‘connection` accessor. Do NOT use this method without having called `dup` on the config object as it relies on shared mutable state.
