EntityModel::DB - database management

DESCRIPTION

Manages database connections and transactions.

new

Does not attempt to connect any database handles, but prepares the context ready for the first request.

dbh

Returns a database handle.

Can only be called within a transaction.

dsn

Data Source string used for connecting to the database.

Currently hardcodes the dbi:Pg: prefix.

_fork_guard

Internal method used to check whether we've forked recently and if so reset the internal state so that we don't try to reuse existing handles.

INHERITED METHODS
