NAME

Catalyst::Helper::Model::DBIC::Schema - Helper for DBIC Schema Models

SYNOPSIS

  script/create.pl model CatalystModelName DBIC::Schema MyApp::SchemaClass \
    [ create=dynamic | create=static ] [ traits=trait1,trait2... ] \
    [ Schema::Loader opts ] [ dsn user pass ] \
    [ other connect_info args ]

DESCRIPTION

Helper for the DBIC Schema Models.

Arguments:

"CatalystModelName" is the short name for the Catalyst Model class being generated (i.e. callable with "$c->model('CatalystModelName')").

"MyApp::SchemaClass" is the fully qualified classname of your Schema, which might or might not yet exist. Note that you should have a good reason to create this under a new global namespace, otherwise use an existing top level namespace for your schema class.

"create=dynamic" instructs this Helper to generate the named Schema class for you, basing it on DBIx::Class::Schema::Loader (which means the table information will always be dynamically loaded at runtime from the database).

"create=static" instructs this Helper to generate the named Schema class for you, using DBIx::Class::Schema::Loader in "one shot" mode to create a standard, manually-defined DBIx::Class::Schema setup, based on what the Loader sees in your database at this moment. A Schema/Model pair generated this way will not require DBIx::Class::Schema::Loader at runtime, and will not automatically adapt itself to changes in your database structure. You can edit the generated classes by hand to refine them.

"traits" is the list of traits to apply to the model, see Catalyst::Model::DBIC::Schema for details.

"Schema::Loader opts" are documented in DBIx::Class::Schema::Loader::Base and some examples are given in "TYPICAL EXAMPLES" below.

"connect_info" arguments are the same as what "connect" in DBIx::Class::Schema expects, and are storage_type-specific. They are documented in "connect_info" in DBIx::Class::Storage::DBI. For DBI-based storage, these arguments are the dsn, username, password, and connect options, respectively. These are optional for existing Schemas, but required if you use either of the "create=" options.

username and password can be omitted for "SQLite" dsns.

Use of either of the "create=" options requires DBIx::Class::Schema::Loader.

TYPICAL EXAMPLES

Use DBIx::Class::Schema::Loader to create a static DBIx::Class::Schema, and a Model which references it:

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass create=static dbi:mysql:foodb myuname mypass

Same, with extra connect_info args user and pass can be omitted for sqlite, since they are always empty

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass create=static dbi:SQLite:foo.db \
    AutoCommit=1 cursor_class=DBIx::Class::Cursor::Cached \
    on_connect_do='["select 1", "select 2"]' quote_names=1

ON WINDOWS COMMAND LINES QUOTING RULES ARE DIFFERENT

In "cmd.exe" the above example would be:

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass create=static dbi:SQLite:foo.db \
    AutoCommit=1 cursor_class=DBIx::Class::Cursor::Cached \
    on_connect_do="[\"select 1\", \"select 2\"]" quote_names=1

Same, but with extra Schema::Loader args (separate multiple values by commas):

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass create=static db_schema=foodb components=Foo,Bar \
    exclude='^(wibble|wobble)$' moniker_map='{ foo => "FOO" }' \
    dbi:Pg:dbname=foodb myuname mypass

Coderefs are also supported:

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass create=static \
    inflect_singular='sub { $_[0] =~ /\A(.+?)(_id)?\z/; $1 }' \
    moniker_map='sub { join(q{}, map ucfirst, split(/[\W_]+/, lc $_[0])); }' \
    dbi:mysql:foodb myuname mypass

See DBIx::Class::Schema::Loader::Base for a list of options

Create a dynamic DBIx::Class::Schema::Loader-based Schema, and a Model which references it (DEPRECATED):

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass create=dynamic dbi:mysql:foodb myuname mypass

Reference an existing Schema of any kind, and provide some connection information for ->config:

  script/myapp_create.pl model CatalystModelName DBIC::Schema \
    MyApp::SchemaClass dbi:mysql:foodb myuname mypass

Same, but don't supply connect information yet (you'll need to do this in your app config, or [not recommended] in the schema itself).

  script/myapp_create.pl model ModelName DBIC::Schema My::SchemaClass

METHODS

mk_compclass

This is called by Catalyst::Helper with the commandline args to generate the files.

run

Can be called on an instance to generate the files.
