Circumflex orm doesn't work with Play 2.1

Question

I've updated the play framework to version 2.1 in my application and it don't work more.

Here is a simple controller:

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))
  }

}

And here is model of a country:

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})"))
}

When page is opened I get a follow error:

[error] application -

Can anyone help me to solve this problem?

Answer 1

Circumflex 2.x doesnt appear to be built against scala 2.10 (which is needed for play 2.1).

The circumflex 3.0 is being built in 2.10, but its current only in snapshot. You can get the snapshot here:

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

Note that the package names have changed from ru.circumflex to pro.savant.circumflex so you may need to refactor your import statements.

Answer 2

I fixed it using these info: reference

First take last version of circumflex from Github:

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

Following the suggestion, change line in the file orm/src/main/scala/relation.scala

line 55:

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

to

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

Now we can compile it, install and use in our Play 2.1 App

cd circumflex
mvn clean install

in case you need only one module:

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

Now edit your project/Build.scala file to add dependency and local rep

  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"
  )
