NAME
CGI::Application::Plugin::DBIC::Schema - Easy DBIx::Class access from CGI::Application, inspired by CGI::Application::Plugin::DBH.SYNOPSIS
use CGI::Application::Plugin::DBIC::Schema (qw/dbic_config schema resultset rs/); sub cgiapp_init{ my $c = shift; my $dsn = $c->param('dsn'); my $dbpw = $c->param('dbpw'); my $dbuser = $c->param('dbuser'); # Provide a default config. $c->dbic_config({schema=>"My::DB", # DBIC class connect_info=>[$dsn,$dbuser,$dbpw] # use same args as DBI connect }); } sub setup { my $c = shift; $c->start_mode('runmode1'); $c->run_modes([qw/runmode1 runmode2/]); } sub runmode1 { my $c = shift; my $id = $c->param('id); $c->resultset("My::DB::DemoTable")->find($id); # do something with the object ... return "found it."; } sub runmode2 { my $c = shift; $c->schema()->resultset("My::DB::DemoTable") ->create({name=>"John Doe", address=>"Any Street"}); return "created it"; }
DESCRIPTION
CGI::Application::Plugin::DBIC::Schema adds easy access to a DBIx::Class::Schema to your Titanium or CGI::Application modules. Lazy loading is used to prevent a database connection from being made if the "schema" method is not called during the request. In other words, the database connection is not created until it is actually needed.DBIx::Class has lots of dependencies, and therefore a certain length of compile time, but it works fine in a CGI environment for low volume sites. If you expect a high volume of traffic, think about FastCGI or other alternatives.
METHODS
schema($name?)
This method will return the default DBIx::Class::Schema instance if no name is provided. Provide a schema name to retrieve an alternate schema. The schema instance is created on the first call to this method, and any subsequent calls will return the same instance.my $schema = $c->schema(); # gets default (unnamed) schema # Or ... my $schem = $c->schema('my_schema_name'); # gets one of named schemas
dbic_config($name?, \%connect_info)
Used to provide your DBIx::Class::Schema class name, an optional config name, and DBI connection parameters. For \%config_info supply the same parameter list that you would for DBI::connect. You may also supply DBIx::Class specifig attributes. For that see DBIx::Class::Storage::DBI for details.The recommended place to call "dbic_config" is in the "cgiapp_init" stage of CGI::Application. If this method is called after the dbic() method has already been accessed, then it will die with an error message.
# Setup default schema config $c->dbic_config({schema=>"My::DB", # DBIC class connect_info=>[$dsn,$dbuser,$dbpw] # use same args as DBI connect }); # Or, provide additional configs by name. $c->dbic_config("another_config", {schema=>"My::Other::DB", connect_info=>[$dsn,$dbuser,$dbpw] });
resultset($config_name?,$resultset_classname)
An alias to $c->schema(...)->resultset(...).This method provides DBIx::Class::Resultset access.
# Use the default dbic schema via 'resultset'. $c->resultset("DBICT::Result::Test")->find($id); # Or use a named config to access resultset via an alternative schema. $c->resultset('another_config', "DBICT::Result::Test")->find($id); # Or use alias short form, 'rs' with default config $c->rs("DBICT::Result::Test")->find($id); # Or use alias short form with alternate config/schema $c->rs('yet_another_schema', "DBICT::Result::Test")->find($id);
