play-slick:找不到桌子

我想在播放2.4.0时使用play-slick 1.0.0。 根据示例(https://github.com/playframework/play-slick/tree/master/samples/basic),我像这样定义了UserTable:

包裹表

import models.User
import scala.slick.driver.JdbcProfile

trait UserTable {
  protected val driver: JdbcProfile
  import driver.api._
  class Users(tag: Tag) extends Table[User](tag, "users"){
    def ID = column[Long]("id", O.PrimaryKey, O.AutoInc)
    def email = column[String]("email", O.NotNull)
    def password = column[String]("password", O.NotNull)
    def * = (ID, email, password) <> (User.tupled, User.unapply)
  }
}

我按照以下方式实施了控制器:

package controllers

import play.api._
import play.api.mvc._
import play.api.db.slick.DatabaseConfigProvider
import play.api.db.slick.HasDatabaseConfig
import tables.UserTable
import scala.slick.driver.JdbcProfile
import play.api.libs.concurrent.Execution.Implicits.defaultContext

import models.User
import tables.UserTable

class UserController extends Controller with UserTable with HasDatabaseConfig[JdbcProfile]{
  val dbConfig = DatabaseConfigProvider.get[JdbcProfile](Play.current)
  import driver.api._

  val Users = TableQuery[Users]

  def index = Action.async {
    db.run(Users.result).map(res => Ok(views.html.User.index(res.toList)))
  }
}

但是,我运行了应用程序并调用了这个控制器,我收到了错误

[SQLException: [SQLITE_ERROR] SQL error or missing database (no such table: users)]

如何创建“用户”表?

答案 0 :(得分:1)

您需要使用现有用户表或通过光滑创建表。

请参阅http://slick.typesafe.com/doc/3.0.0/gettingstarted.html#populating-the-database

您需要在应用程序中运行db.run(Users.schema.create)。
