use DBIx::Class::Admin;

# ddl manipulation
my $admin = DBIx::Class::Admin->new(
  schema_class=> 'MY::Schema',
  sql_dir=> $sql_dir,
  connect_info => { dsn => $dsn, user => $user, password => $pass },
);

# create SQLite sql
$admin->create('SQLite');

# create SQL diff for an upgrade
$admin->create('SQLite', {} , "1.0");

# upgrade a database
$admin->upgrade();

# install a version for an unversioned schema

REQUIREMENTS

The Admin interface has additional requirements not currently part of DBIx::Class. See DBIx::Class::Optional::Dependencies for more details.

ATTRIBUTES

schema_class

the class of the schema to load

schema

A pre-connected schema object can be provided for manipulation

resultset

a resultset from the schema to operate on

where

a hash ref or json string to be used for identifying data to manipulate

set

a hash ref or json string to be used for inserting or updating data

attrs

a hash ref or json string to be used for passing additional info to the ->search call

connect_info

connect_info the arguments to provide to the connect call of the schema_class

config_file

config_file provide a config_file to read connect_info from, if this is provided config_stanze should also be provided to locate where the connect_info is in the config The config file should be in a format readable by Config::Any.

config_stanza

config_stanza for use with config_file should be a '::' delimited 'path' to the connection information designed for use with catalyst config files

config

Instead of loading from a file the configuration can be provided directly as a hash ref. Please note config_stanza will still be required.

sql_dir

The location where sql ddl files should be created or found for an upgrade.

sql_type

The type of sql dialect to use for creating sql files from schema

version

Used for install, the version which will be 'installed' in the schema

preversion

Previous version of the schema to create an upgrade diff for, the full sql for that version of the sql must be in the sql_dir

force

Try and force certain operations.

quiet

Be less verbose about actions

trace

Toggle DBIx::Class debug output

METHODS

create

Arguments: $sqlt_type, \%sqlt_args, $preversion

create will generate sql for the supplied schema_class in sql_dir. The flavour of sql to generate can be controlled by supplying a sqlt_type which should be a SQL::Translator name.

Arguments for SQL::Translator can be supplied in the sqlt_args hashref.

Optional preversion can be supplied to generate a diff to be used by upgrade.

upgrade

Arguments: <none>

upgrade will attempt to upgrade the connected database to the same version as the schema_class. MAKE SURE YOU BACKUP YOUR DB FIRST

install

Arguments: $version

install is here to help when you want to move to DBIx::Class::Schema::Versioned and have an existing database. install will take a version and add the version tracking tables and 'install' the version. No further ddl modification takes place. Setting the force attribute to a true value will allow overriding of already versioned databases.

deploy

Arguments: $args

deploy will create the schema at the connected database. $args are passed straight to "deploy" in DBIx::Class::Schema.

insert

Arguments: $rs, $set

insert takes the name of a resultset from the schema_class and a hashref of data to insert into that resultset

update

Arguments: $rs, $set, $where

update takes the name of a resultset from the schema_class, a hashref of data to update and a where hash used to form the search for the rows to update.

delete

Arguments: $rs, $where, $attrs

delete takes the name of a resultset from the schema_class, a where hashref and a attrs to pass to ->search. The found data is deleted and cannot be recovered.

select

Arguments: $rs, $where, $attrs

select takes the name of a resultset from the schema_class, a where hashref and a attrs to pass to ->search. The found data is returned in a array ref where the first row will be the columns list.
