NAME

       Dancer::Plugin::DBIC - DBIx::Class interface for Dancer applications

VERSION

       version 0.1506

SYNOPSIS

	   use Dancer;
	   use Dancer::Plugin::DBIC 'schema';

	   get '/users/:id' => sub {
	       my $user = schema->resultset('User')->find(param 'id');
	       template user_profile => {
		   user => $user
	       };
	   };

	   dance;

DESCRIPTION

       This plugin makes it very easy to create Dancer applications that interface with databases.  It automatically exports the keyword "schema"
       which returns a DBIx::Class::Schema object.  You just need to configure your database connection information.  For performance, schema
       objects are cached in memory and are lazy loaded the first time they are accessed.

CONFIGURATION

       Configuration can be done in your Dancer config file.  This is a minimal example. It defines one database named "default":

	   plugins:
	     DBIC:
	       default:
		 dsn: dbi:SQLite:dbname=some.db

       In this example, there are 2 databases configured named "default" and "foo":

	   plugins:
	     DBIC:
	       default:
		 dsn: dbi:SQLite:dbname=some.db
		 schema_class: My::Schema
	       foo:
		 dsn:  dbi:mysql:foo
		 schema_class: Foo::Schema
		 user: bob
		 pass: secret
		 options:
		   RaiseError: 1
		   PrintError: 1

       Each database configured must have a dsn option.  The dsn option should be the DBI driver connection string.  All other options are
       optional.

       If you only have one schema configured, or one of them is named "default", you can call "schema" without an argument to get the only or
       "default" schema, respectively.

       If a schema_class option is not provided, then DBIx::Class::Schema::Loader will be used to dynamically load the schema based on the dsn
       value.  This is for convenience only and should not be used in production.  See "SCHEMA GENERATION" below for caveats.

       The schema_class option, should be a proper Perl package name that Dancer::Plugin::DBIC will use as a DBIx::Class::Schema class.
       Optionally, a database configuation may have user, pass, and options parameters as described in the documentation for "connect()" in DBI.

       You may also declare your connection information in the following format (which may look more familiar to DBIC users):

	   plugins:
	     DBIC:
	       default:
		 connect_info:
		   - dbi:mysql:foo
		   - bob
		   - secret
		   -
		     RaiseError: 1
		     PrintError: 1

USAGE

       This plugin provides just the keyword "schema" which returns a DBIx::Class::Schema object ready for you to use.	If you have configured
       only one database, then you can call "schema" with no arguments:

	   my $user = schema->resultset('User')->find('bob');

       If you have configured multiple databases, you can still call "schema" with no arguments if there is a database named "default" in the
       configuration.  Otherwise, you must provide "schema()" with the name of the database:

	   my $user = schema('foo')->resultset('User')->find('bob');

SCHEMA GENERATION

       There are two approaches for generating schema classes.	You may generate your own DBIx::Class classes by hand and set the corresponding
       "schema_class" setting in your configuration as shown above.  This is the recommended approach for performance and stability.

       It is also possible to have schema classes automatically generated via introspection (powered by DBIx::Class::Schema::Loader) if you omit
       the "schema_class" configuration setting.  However, this is highly discouraged for production environments.  The "v7" naming scheme will be
       used for naming the auto generated classes.  See "naming" in DBIx::Class::Schema::Loader::Base for more information about naming.

       For generating your own schema classes, you can use the dbicdump command line tool provided by DBIx::Class::Schema::Loader to help you.
       For example, if your app were named Foo, then you could run the following from the root of your project directory:

	   dbicdump -o dump_directory=./lib Foo::Schema dbi:SQLite:/path/to/foo.db

       For that example, your "schema_class" setting would be "Foo::Schema".
