413
414 ## Via DBIx::Class

416 my $schema = MyApp::Schema->connect("dbi:SQLite:something.db");

421 ## Standalone
422 use MyApp::Schema;

426 my $trans = SQL::Translator->new (
427 parser => 'SQL::Translator::Parser::DBIx::Class',
428 parser_args => {
429 package => $schema,
430 add_fk_index => 0,

439
440=head1 DESCRIPTION
441
442This class requires L<SQL::Translator> installed to work.
443
444C<SQL::Translator::Parser::DBIx::Class> reads a DBIx::Class schema,
445interrogates the columns, and stuffs it all in an $sqlt_schema object.
446
447Its primary use is in deploying database layouts described as a set
448of L<DBIx::Class> classes, to a database. To do this, see
449L<DBIx::Class::Schema/deploy>.
450
451This can also be achieved by having DBIx::Class export the schema as a
452set of SQL files ready for import into your database, or passed to
453other machines that need to have your application installed but don't
454have SQL::Translator installed. To do this see
455L<DBIx::Class::Schema/create_ddl_dir>.
456
457=head1 PARSER OPTIONS
458
459=head2 add_fk_index
460
461Create an index for each foreign key.
462Enabled by default, as having indexed foreign key columns is normally the
463sensible thing to do.

472
473Limit the amount of parsed sources by supplying an explicit list of source names.
