Is there a way to use Anorm like a regular ORM? I'd like to have a method that just inserts an element provided.
def insert[T](element: T)(implicit connection: Connection) = {
element.insert(connection)
}
I can definitely implement it by myself, but feels like I'm re-implementing an ORM... Old anorm version had this Magic[T] but I can't see it now
The documentation clearly states that Anorm is not an ORM (and will never be).
As indicated, to insert or update a T value, an instance of the ToStatement typeclass must be provided.
Some macros are provided to automatically materialize such instance.
import anorm.{ Macro, SQL, ToParameterList }
import anorm.NamedParameter
case class Bar(v: Int)
val bar1 = Bar(1)
// Convert all supported properties as parameters
val toParams1: ToParameterList[Bar] = Macro.toParameters[Bar]
val params1: List[NamedParameter] = toParams1(bar1)
// --> List(NamedParameter(v,ParameterValue(1)))
val names1: List[String] = params1.map(_.name)
// --> List(v)
val placeholders = names1.map { n => s"{$n}" } mkString ", "
// --> "{v}"
val generatedStmt = s"""INSERT INTO bar(${names1 mkString ", "}) VALUES ($placeholders)"""
val generatedSql1 = SQL(generatedStmt).on(params1: _*)
