NAME

SQL::Translator::Parser::DBIx::Class - Create a SQL::Translator schema from a DBIx::Class::Schema instance

SYNOPSIS

## Via DBIx::Class
use MyApp::Schema;
my $schema = MyApp::Schema->connect("dbi:SQLite:something.db");
$schema->create_ddl_dir();
## or
$schema->deploy();

## Standalone
use MyApp::Schema;
use SQL::Translator;

my $schema = MyApp::Schema->connect;
my $trans  = SQL::Translator->new (
     parser      => 'SQL::Translator::Parser::DBIx::Class',
     parser_args => {
         dbic_schema => $schema,
         add_fk_index => 0,
         sources => [qw/
           Artist
           CD
         /],
     },
     producer    => 'SQLite',
    ) or die SQL::Translator->error;
my $out = $trans->translate() or die $trans->error;

DESCRIPTION

This class requires SQL::Translator installed to work.

SQL::Translator::Parser::DBIx::Class reads a DBIx::Class schema, interrogates the columns, and stuffs it all in an $sqlt_schema object.

Its primary use is in deploying database layouts described as a set of DBIx::Class classes, to a database. To do this, see "deploy" in DBIx::Class::Schema.

This can also be achieved by having DBIx::Class export the schema as a set of SQL files ready for import into your database, or passed to other machines that need to have your application installed but don't have SQL::Translator installed. To do this see "create_ddl_dir" in DBIx::Class::Schema.

PARSER OPTIONS

dbic_schema

The DBIx::Class schema (either an instance or a class name) to be parsed. This argument is in fact optional - instead one can supply it later at translation time as an argument to "translate" in SQL::Translator. In other words both of the following invocations are valid and will produce conceptually identical output:

my $yaml = SQL::Translator->new(
  parser => 'SQL::Translator::Parser::DBIx::Class',
  parser_args => {
    dbic_schema => $schema,
  },
  producer => 'SQL::Translator::Producer::YAML',
)->translate;

my $yaml = SQL::Translator->new(
  parser => 'SQL::Translator::Parser::DBIx::Class',
  producer => 'SQL::Translator::Producer::YAML',
)->translate(data => $schema);

add_fk_index

Create an index for each foreign key. Enabled by default, as having indexed foreign key columns is normally the sensible thing to do.

sources

Arguments: \@class_names

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