DESCRIPTION

This Yancy backend allows you to connect to a DBIx::Class schema to manage the data inside.

See Yancy::Backend for the methods this backend has and their return values.

Backend URL

The URL for this backend takes the form dbic://<schema_class>/<dbi_dsn> where schema_class is the DBIx::Class schema module name and dbi_dsn is the full DBI data source name (DSN) used to connect to the database.

Collections

The collections for this backend are the names of the DBIx::Class::Row classes in your schema, just as DBIx::Class allows in the $schema->resultset method.

So, if you have the following schema:

    package My::Schema;
    use base 'DBIx::Class::Schema';
    __PACKAGE__->load_namespaces;

    package My::Schema::Result::People;
    __PACKAGE__->table( 'people' );
    __PACKAGE__->add_columns( qw/ id name email / );

    package My::Schema::Result::Business
    __PACKAGE__->table( 'business' );
    __PACKAGE__->add_columns( qw/ id name email / );

You could map that schema to the following collections:

    {
        backend => 'dbic://My::Schema/dbi:SQLite:test.db',
        collections => {
            People => {
                properties => {
                    id => {
                        type => 'integer',
                        readOnly => 1,
                    },
                    name => { type => 'string' },
                    email => { type => 'string' },
                },
            },
            Business => {
                properties => {
                    id => {
                        type => 'integer',
                        readOnly => 1,
                    },
                    name => { type => 'string' },
                    email => { type => 'string' },
                },
            },
        },
    }
