Play フレームワーク 2.1.0 で Slick 1.0.0 を使用しています。テーブルをクエリすると、次のエラーが発生しUsers
ます。の値はLOGIN_ID
DB で null です。私が実行しているクエリは次のとおりです。
val user = { for { u <- Users if u.providerId === id.id } yield u}.first
これにより、次のエラーが発生します。

私のユーザーテーブルは次のように定義されています:
package models
import scala.slick.driver.MySQLDriver.simple._
case class User(userId:String,email:String,loginId:String,fullName:String,firstName:String,lastName:String,location:String,homeTown:String,providerId:String,provider:String,state:String,zip:String,accessKey:String,refreshKey:String,avatarUrl:String)
object Users extends Table[User]("USERS") {
def userId = column[String]("USER_ID", O.PrimaryKey) // This is the primary key column
def email = column[String]("EMAIL",O.NotNull)
def loginId = column[String]("LOGIN_ID",O.Nullable)
def fullName = column[String]("FULL_NAME",O.NotNull)
def firstName = column[String]("FIRST_NAME",O.Nullable)
def lastName = column[String]("LAST_NAME",O.Nullable)
def location = column[String]("LOCATION",O.Nullable)
def homeTown = column[String]("HOME_TOWN",O.Nullable)
def providerId = column[String]("PROVIDER_ID",O.Nullable)
def provider = column[String]("PROVIDER",O.Nullable)
def state = column[String]("STATE",O.Nullable)
def zip = column[String]("ZIP",O.Nullable)
def accessKey = column[String]("ACCESS_KEY",O.Nullable)
def refreshKey = column[String]("REFRESH_KEY",O.Nullable)
def avatarUrl = column[String]("AVATAR_URL",O.Nullable)
// Every table needs a * projection with the same type as the table's type parameter
def * = userId ~ email ~ loginId ~ fullName ~ firstName ~ lastName ~ location ~ homeTown ~ providerId ~ provider ~ state ~ zip ~ accessKey ~ refreshKey ~ avatarUrl <> (User,User.unapply _)
}
助けてください。Slick は DB からの Null 値を処理できないようですか?
