DESCRIPTION

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

METHODS

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

read_schema

While reading the various sources, this method will check each source's result_class for the existence of a yancy method. If it exists, that will be called, and must return the initial JSON schema for Yancy.

A very useful possibility is for that JSON schema to just contain <{ 'x-ignore' = 1 }>>.

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.

Schema Names

The schema names 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 to the following schema names:

{
    backend => 'dbic://My::Schema/dbi:SQLite:test.db',
    schema => {
        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' },
            },
        },
    },
}
