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

       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

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.
