Examples
Setup
To use this library you need to create a configuration table in database with a key and value text fields.
Easiest way to do this is just by running:
import org.virtuslab.config.ConfigurationEntries
import play.api.db.slick.Config.driver.simple._
ConfigurationEntries.ddl.create
Or adding following SQL (it's from PostgreSQL, syntax may vary) to your setup or evolution scripts:
CREATE TABLE configuration
(
key character varying(254) NOT NULL,
value character varying(254) NOT NULL,
CONSTRAINT configuration_pkey PRIMARY KEY (key)
);
Usage
TODO
Extensions
Serialization and de-serialization of properties are based on a type-class called ConfigurationSerializer:
trait ConfigurationSerializer[A] {
def write(a: A): String
def read(s: String): A
}
This library comes with instances of this type-class for several types, but you can easily create your own instances of it by placing an implicit val (or def or object) in scope.
