|
||||
SL::DB - Database access class for all RDB objects
|
||||
=head1 FUNCTIONS
|
||||
=over 4
|
||||
=item C<create $domain, $type>
|
||||
Registers the database information with Rose, creates a cached
|
||||
connection and executes initial SQL statements. Those can include
|
||||
setting the time & date format to the user's preferences.
|
||||
=item C<dbi_connect $dsn, $login, $password, $options>
|
||||
Forwards the call to L<SL::DBConnect/connect> which connects to the
|
||||
database. This indirection allows L<SL::DBConnect/connect> to route
|
||||
the calls through L<DBIx::Log4Perl> if this is enabled in the
|
||||
configuration.
|
||||
=item C<with_transaction $code_ref, @args>
|
||||
Executes C<$code_ref> within a transaction, starting one if none is
|
||||
currently active. This is just a shortcut for the following code:
|
||||
# Verbose code in caller (an RDBO instance):
|
||||
my $worker = sub {
|
||||
# do stuff with $self
|
||||
};
|
||||
return $self->db->in_transaction ? $worker->() : $self->db->do_transaction($worker);
|
||||
Now the version using C<with_transaction>:
|
||||
return $self->db->with_transaction(sub {
|
||||
# do stuff with $self
|
||||
});
