Several data source in Play 2 framework with slick

Question

How can I configure and use several data source in Play 2.5.x Framework with Slick? For example, one data source should be MySQL and another PostgreSQL.

  slick.dbs.default.driver = "utils.db.TetraoPostgresProfile$"
  slick.dbs.default.db.driver = "org.postgresql.Driver"
  slick.dbs.default.db.url = "jdbc:postgresql://localhost:5432/templatesite_db"
  slick.dbs.default.db.user = "user"
  slick.dbs.default.db.password = "pass"

  slick.dbs.secondary.driver = "slick.jdbc.MySQLProfile$"
  slick.dbs.secondary.db.driver = "com.mysql.jdbc.Driver"
  slick.dbs.secondary.db.url = "jdbc:mysql://localhost:3306/dbName"
  slick.dbs.secondary.db.user = "root"
  slick.dbs.secondary.db.password = "pass"

Answer 1

This is directly addressed in the ScalaDatabase docummentation page:

// inject "orders" database instead of "default"
class ScalaInjectNamed @Inject()(
  @NamedDatabase("orders") db: Database) extends Controller {
  // do whatever you need with the db
}
