HasDatabaseConfigProvider

Mix-in this trait if you need a Slick database and profile, and you are using dependency injection for obtaining an instance of DatabaseConfigProvider. If you are not using dependency injection, then prefer mixing HasDatabaseConfig instead.

This trait is useful if you need to define a Slick table or need to execute some operation in the database.

Example

// model definition
class Cat(name: String, color: String)
// DAO definition
class CatDAO @Inject()(protected val dbConfigProvider: DatabaseConfigProvider) extends HasDatabaseConfigProvider[RelationalProfile] {
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).
