Play Slick Global Lookup setup deprecated message

As stated in Play Slick documentation a DatabaseConfig object can be obtained via Global Lookup:

val dbConfig = DatabaseConfigProvider.get[JdbcProfile](Play.current)

However I get the following compilation warning stating that current is deprecated and that I should use DI instead:

[warn] C:\myapp\app\test\Test.scala:28: method current in object Play is deprecated: This is a static reference to application, use DI instead

Am I forced to use DI instead of global lookup? With the deprecation warning the database connection works fine.

Solution

  • Either inject actually Play app (and pass it as parameter as you did) or better, inject DatabaseConfigProvider itself - in that way it won't need Application:

    @Singleton
class DbAccessPlayConfig @Inject()(dbConfigProvider: DatabaseConfigProvider) {
  val dbConfig = dbConfigProvider.get[JdbcProfile]
}
