Circumflex orm 不适用于 Play 2.1

Question

我已经在应用程序中将play框架更新到2.1版本，但它无法正常工作。

这里有一个简单的控制器：

package controllers
import play.api._
import play.api.mvc._
import models.Country
import ru.circumflex.orm._
object Application extends Controller {
  def index = Action {
      val co = Country AS "co"
      val q = SELECT (co.*) FROM (co)
      val countries: Seq[Country] = q.list()
      Ok(views.html.index(countries))
  }
}

这是一个国家的模型：

package models
import ru.circumflex.orm.{TextField, Table, Record}
import java.util.regex.Pattern
class Country extends Record[String, Country] {
  def PRIMARY_KEY = code
  def relation = Country
  def this(code: String, name: String) = {
    this()
    this.code := code
    this.name := name
  }
  val code: TextField[Country] = "code".VARCHAR(2).NOT_NULL
  val name = "name".TEXT.NOT_NULL
  def cities = inverseMany(City.country)
  override def toString = name.getOrElse("unknow")
}
object Country extends Country with Table[String, Country] {
  val codeKey = UNIQUE(code)
  val codeChk = CONSTRAINT("code_chk").CHECK("code IN ('ch', 'us', 'uk', 'fr', 'es', 'it', 'pt', 'by')")
  val idx = "country_code_idx".INDEX("LOWER(code)").USING("btree").UNIQUE
  validation.notNull(_.code)
            .notEmpty(_.code)
            .pattern(_.code, Pattern.compile("(?i:[a-z]{2})"))
}

当页面打开时，我得到一个以下错误：

[error] application -

有人能帮我解决这个问题吗？

Answer 1

我使用以下信息修复了它：引用

首先从Github:获取扬抑符的最后一个版本

git clone git://github.com/inca/circumflex.git

根据建议，更改文件orm/src/main/scala/relation.scala 中的行

第55行：

val _recordClass: Class[R] = Class.forName(

到

val _recordClass: Class[R] = this.getClass().getClassLoader().loadClass(

现在我们可以编译它，安装并在我们的Play 2.1应用中使用

cd circumflex
mvn clean install

如果您只需要一个模块：

cd circumflex
mvn clean install -pl <circumflex-orm> -am

现在编辑您的project/Build.scala文件以添加依赖项和本地代表

  val appDependencies = Seq(    
   "pro.savant.circumflex" % "circumflex-orm" % "3.1-SNAPSHOT"
  )
  val main = play.Project(appName, appVersion, appDependencies).settings(defaultScalaSettings:_*).settings(
    resolvers += "Local Maven Repository" at "file:"+Path.userHome.absolutePath+"/.m2/repository"
  )

Answer 2

扬抑符2.x似乎不是针对scala 2.10构建的（这是2.1游戏所需要的）。

扬抑符3.0是在2.10中构建的，但其当前版本仅在快照中。你可以在这里获得快照：

https://oss.sonatype.org/content/repositories/snapshots/

请注意，程序包名称已从ru.e扬抑符更改为pro.savant.e扬抑符号，因此您可能需要重构导入语句。
