我正在创建一个包含员工列表的应用程序。管理员可以查看员工列表并更改其数据。当他点击＆＃34;改变＆＃34;按钮，html表单应该填充选定的员工数据，以便他可以更改它。我在play框架中使用了标准机制，但它不起作用。我正在调试它，一切看起来都不错（员工数据设置为表格）但它没有显示在我的html表单上......我不明白为什么......
def loadEmployee(id: Int) = Action { implicit request =>
val loadedEmployee = EmployeeService.getEmployee(id)
val employee = Await.result(loadedEmployee, Duration(5, SECONDS)).get
val employees = Await.result(EmployeeService.listAllEmployees, Duration(5, SECONDS))
val form = EmployeeForm.form.fill(EmployeeFormData(employee.name, employee.additionalInformation, employee.resume))
Ok(views.html.index(form,employees))
}

@(employeeForm: Form[models.EmployeeFormData],employees : Seq[models.Employee])

您的控制器代码看起来没问题 - 您fill Form[EmployeeFormData]并将其传递给您的模板。麻烦的是，你永远不会在模板中使用你的employeeForm - 这种形式无法填充。
如果您阅读了showing forms in a view template的Play文档，您会发现有helper整个系列可用于此目的。在许多情况下，它们几乎和简单的HTML＆＃34;像你这样的版本。这是一个例子：
您的位置：
<div class="input-group">
<span class="input-group-addon"><span class="glyphicon glyphicon-employee"></span></span>
<input type="text" id="name" name="name" value="" placeholder="First Name" class="form-control input-lg" required>
</div>
您需要：
<div class="input-group">
<span class="input-group-addon"><span class="glyphicon glyphicon-employee"></span></span>
@helper.inputText(
employeeForm("name"),
'id -> "name",
'placeholder -> "First Name",
'class -> "form-control input-lg",
'required -> "true"
)
</div>
注意如何通过在'字符前面添加任意数量的任意参数到生成的HTML中。这可能非常方便，例如，如果您想在输入上设置额外的data-属性。
