使用Play App 2.4.6的i18n问题

我有一个简单的Play Framework 2.4.6项目,其国际化配置为Play描述文档。 我的文件是这样的: 1)控制器:

package controllers

import play.api._
import play.api.mvc._
import play.api.i18n.{I18nSupport,MessagesApi,Messages,Lang}
import play.api.i18n.Messages.Implicits._
import play.api.Play.current
import javax.inject.Inject

class Application @Inject()(val messagesApi: MessagesApi) extends Controller with  I18nSupport {

  def index = Action { implicit request =>
    Ok(views.html.index("Your new application is ready."))
  }

}

2)消息资源文件:

application.name = Orthoclinic
welcome = Welcome to play!

3)主要模板:

@(title: String)(content: Html)(implicit messages: Messages)

<!DOCTYPE html>

<html lang="en">
    <head>
        <title>@title</title>
        <link rel="stylesheet" media="screen" href="@routes.Assets.versioned("/assets/stylesheets/main.css")">
        <link rel="shortcut icon" type="image/png" href="@routes.Assets.versioned("/assets/images/favicon.png")">
        <script src="@routes.Assets.versioned("/assets/javascripts/hello.js")" type="text/javascript"></script>
    </head>
    <body>
        @Messages("application.name")
        @content
    </body>
</html>

4)索引模板:

@(message: String)

@main("Welcome to Play") {

    @play20.welcome(message)


}

5)路由文件:

# Home page
GET     /                           controllers.Application.index

# Map static resources from the /public folder to the /assets URL path
GET     /assets/*file               controllers.Assets.versioned(path="/public", file: Asset)

6)应用程序配置文件:

play.crypto.secret = "k1mIneaPlay_pRoJ"
play.i18n.langs = [ "en", "en-us", "pt-br", "es" ]



Calling ./activator reload compile run my result is that:
[error] /home/josenildo/scala-ide/workspace/orthoclinic-app/app/views/main.scala.html:13: could not find implicit value for para
meter messages: play.api.i18n.Messages
[error]         @Messages("application.name")

我已按照Play文档here上的i18n最新版本的文档进行操作。 该实施有什么问题?

答案 0 :(得分:0)

您只需要在messages模板中添加隐式index.scala.html参数:

@(message: String)(implicit messages: Messages)

@main("Welcome to Play") {

    @play20.welcome(message)
}

每当您通过Messages使用i18n时,隐式@Messages("my.key")实例都需要在范围内,messages具有将由编译器提供的相应隐式import play.api.i18n.Messages.Implicits._参数(请参阅签名) here)。

,您可能希望摆脱I18NSupport,因为如果您的控制器扩展relist,则不应该要求它,并且确实可能​​导致有关模糊的错误隐含的价值观。
