我无法通过模块securesocial为play2自定义视图,“找不到:输入RequestHeader”

我正在尝试使用play 2

自定义模块“securesocial”提出的视图

我已经做的是:

1 /创建一个新的插件名称SecureViewsPlugin,实现“controllers / SecuresViewsPlugin.scala”下的TemplatesPlugin

package controllers

import play.api.mvc.{RequestHeader, Request}
import play.api.templates.Html
import securesocial.controllers.Registration.RegistrationInfo
import securesocial.controllers.TemplatesPlugin
import securesocial.core.{SecuredRequest, SocialUser}
import play.api.data.Form
import securesocial.core.SecureSocial._
import securesocial.controllers.PasswordChange.ChangeInfo


class SecureViewsPlugin(application: App) extends TemplatesPlugin {

  override def getLoginPage[A](implicit request: Request[A], form: Form[(String, String)],
                               msg: Option[String] = None): Html =
  {
    views.html.secure.login(form, msg)
  }

  override def getSignUpPage[A](implicit request: Request[A], form: Form[RegistrationInfo], token: String): Html = {
    views.html.secure.Registration.signUp(form, token)
  }

(..)

2 /我用以下文件更新了play.plugins文件:

1500:com.typesafe.plugin.CommonsMailerPlugin
9996:securesocial.core.providers.utils.DefaultPasswordValidator
9997:controllers.SecureViewsPlugin

3 /我复制了“views / secure”文件夹中的不同视图

/Views
     /secure
         /inputFieldConstructor.scala.html
         /login.scala.html
         /(...)

这是我总是得到的错误的开始

not found: type RequestHeader

->@(loginForm: Form[(String,String)], errorMsg: Option[String] = None)(implicit request: RequestHeader)

[error]     views.html.secure.login(form, msg)
[error]  
login.scala.html

我试图删除“(隐式请求:RequestHeader)”,但后来我收到了这个错误

type mismatch; found : play.api.data.Form[(String, String)] required: play.data.Form[(java.lang.String, java.lang.String)]

我猜我没有以正确的方式做到这一点。

我无法弄清楚为什么我会收到这些错误

我有同样的问题,或者非常相似。看看这是否可以帮到你:

错误:

[error] C:\workspace\zenplanning\app\views\index.scala.html:0: not found: type RequestHeader
[error] C:\workspace\zenplanning\app\views\index.scala.html:1: not found: type RequestHeader
[error] @(loginForm: play.api.data.Form[(String,String)], errorMsg: Option[String] = None)(implicit request: RequestHead
er)
[error]                                                                                                     ^

play.PlayExceptions$CompilationException: Compilation error[not found: type RequestHeader]

<强>原因:

我认为这是因为securesocial在您的路由器上使用scala而我在Play项目中使用Java。发送的RequestHeader在Scala(play.api.mvc.RequestHeader)中,但我的模板在Java中期待(play.mvc.RequestHeader)。

<强>解决方案

要解决此问题,我在自定义login.scala.html中修改了:

@(loginForm: play.api.data.Form[(String,String)], errorMsg: Option[String] = None)(implicit request: RequestHeader)

对此:

@(loginForm: play.api.data.Form[(String,String)], errorMsg: Option[String] = None)(implicit request: play.api.mvc.RequestHeader)

答案 1 :(得分:2)

您必须执行以下操作:

在所有Views / secure /...*。scala.html文件中:

用play.api.mvc.RequestHeader替换:RequestHeader          使用play.api.data.Form

表单[String,String]或Form [String]

例如在startSignUp.scala.html文件中,更改原始文件:

@(startForm:Form [String])(隐式请求:RequestHeader)

@(startForm:play.api.data.Form [String])(隐式请求:play.api.mvc.RequestHeader)

答案 2 :(得分:0)

阿巴斯提到了让你自己的模板工作的第一步。

但对我而言仍然没有成功。引发了这个异常:

play.api.PlayException: Cannot load plugin [Plugin [controllers.MyTemplatePlugin] cannot been instantiated.]
...
Caused by: java.lang.NoSuchMethodException: controllers.MyTemplatePlugin.<init>(play.Application)

解决此问题的方法是从

调整模板类的构造函数

class MyTemplatePlugin(application: Application) extends TemplatesPlugin

class MyTemplatePlugin(application: play.Application) extends TemplatesPlugin
