trait HasDatabaseConfig[P <: BasicProfile] extends AnyRef
Mix-in this trait if you need a Slick database and profile. This is useful if you need to define a Slick table or need to execute some operation in the database.
There is only one abstract field, dbConfig
, which you can implement by calling DatabaseConfigProvider.get
.
If you are injecting DatabaseConfigProvider
instances using dependency injection, prefer using the trait
HasDatabaseConfigProvider
instead of this one.
Example
// model definition class Cat(name: String, color: String) // DAO definition class CatDAO extends HasDatabaseConfig[RelationalProfile] { protected val dbConfig = DatabaseConfigProvider.get[RelationalProfile](Play.current) import profile.api._ private val Cats = TableQuery[CatsTable] def all() = db.run(Cats.result) def insert(cat: Cat) = db.run(Cats += cat) // Slick table definition private class CatsTable(tag: Tag) extends Table[Cat](tag, "CAT") { def name = column[String]("NAME", O.PrimaryKey) def color = column[String]("COLOR") def * = (name, color) <> (Cat.tupled, Cat.unapply _) } }
Of course, you do not need to define a DAO to use this trait (the above it is really just an example of usage).
