# Routes
# This file defines all application routes (Higher priority routes first)
# ~~~~

# Home page
GET     /                   controllers.Application.index()

# Tasks
GET     /tasks              controllers.Application.tasks()
POST    /tasks              controllers.Application.newTask()
POST    /tasks/:id/delete   controllers.Application.deleteTask(id: Long)

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

网址：

http://localhost:9000/tasks/2/delete

错误：

Action not found

For request 'GET /tasks/2/delete'
These routes have been tried, in this order:

1 GET   /                          controllers.Application.index()
2 GET   /tasks                     controllers.Application.tasks()
3 POST  /tasks                     controllers.Application.newTask()
4 POST  /tasks/$id<[^/]+>/delete   controllers.Application.deleteTask(id:Long)
5 GET   /assets/$file<.+>          controllers.Assets.at(path:String = "/public", file:String)

HTML片段：

<form action="/tasks/2/delete" method="POST" >
   <input type="submit" value="Delete">
</form>

我不明白为什么规则＃4无法适用。

我的错误在哪里？

最佳答案

我终于完成了自己的POST请求，以添加缺少的ID：

@(tasks: List[Task], taskForm: Form[Task])

@import helper._

@main("Todo list") {
    <h1>@tasks.size() task(s)</h1>
    <ul>
    @for(task <- tasks) {
        <li>
        @task.label
        @form(routes.Application.deleteTask(task.id)) {
            <input type="hidden" id="id" value="@task.id"><!-- *** added ***-->
            <input type="submit" value="Delete">
        }
        </li>
    }
    </ul>

    <h2>Add a new task</h2>
    @form(routes.Application.newTask()) {
        @inputText(taskForm("label"))
        <input type="submit" value="Create">
    }
}

产生的HTML为：

<form action="/tasks/1/delete" method="POST" >
   <input type="hidden" id="id" value="1">
   <input type="submit" value="Delete">
</form>

在PlayFramework 2.1.5之上执行的PlayFramework 2.2.0的Todolist示例效果不佳...
