使用jade的scalate scalatra NoValueSetException

Question

我正在使用Scalatra和Scalate和Jade。当我尝试应用一个带有值的模板时，值没有应用于模板，我得到一个NoValueSetException ...这是我的代码：

// --------- In PostsServlet ------------------
get("/:page") {
  /*
  val page:Int = params.getOrElse("page", "1").toInt
  val posts = PostCollection.page(page)
  */
  contentType="text/html"
  jade("/index.jade", "foo" -> "bar")
}


// ------------------ In index.jade ----------------------
-@ var foo : String

-attributes("title") = "Circuits Of Imagination"
-attributes("headline") = "Writings"

和例外：

The value for 'foo' was not set
org.fusesource.scalate.NoValueSetException: The value for 'foo' was not set
at org.fusesource.scalate.RenderContext$$anonfun$attribute$1.apply(RenderContext.scala:159)
at org.fusesource.scalate.RenderContext$$anonfun$attribute$1.apply(RenderContext.scala:159)
at org.fusesource.scalate.RenderContext$class.attributeOrElse(RenderContext.scala:167)

尝试通过以下命令清除临时/生成的文件

sbt clean clean-files

然后启动Jetty服务器。这可能有所帮助。
