=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> with parameters C<@args> within a transaction,
|
|
starting one if none is currently active. Example:
|
|
|
|
return $self->db->with_transaction(sub {
|
|
# do stuff with $self
|
|
});
|
|
|
|
One big difference to L<Rose::DB/do_transaction> is the return code
|
|
handling. If a transaction is already active then C<with_transcation>
|
|
simply returns the result of calling C<$code_ref> as-is.
|
|
|
|
Otherwise the return value depends on the result of the underlying
|
|
transaction. If the transaction fails then C<undef> is returned in
|
|
scalar context and an empty list in list context. If the transaction
|
|
succeeds then the return value of C<$code_ref> is returned preserving
|
|
context.
|
|
|
|
So if you want to differentiate between "transaction failed" and
|
|
"succeeded" then your C<$code_ref> should never return C<undef>
|
|
itself.
