javascript – Angular 2错误 – 没有使用RC4版本将“exportAs”设置为“ngModel”的指令

https://angular.io/docs/ts/latest/guide/forms.html

在这个验证和使用表单API,我已设置ngModel值,如#name =“id”#id =“ngModel”,并抛出脚本错误.但如果我将#id =“ngModel”设置为#id =“ngForm”,它就会解决.但对于我的情况,我必须将我的模型值设置为ngModel.

下面是我的html页面.

<form (ngSubmit)="onSubmit()" #myForm="ngForm">
  <div class="form-group">
  <label class="control-label" for="id">Employee ID</label>
    <input type="text" class="form-control" required [(ngModel)]="model.id" #name="id"  #id="ngModel" >
    <div [hidden]="id.valid || id.pristine" class="alert alert-danger">
      Employee ID is required
    </div>
  </div>
  <div class="form-group">
    <label for="name">Employee Name</label>
    <input type="text" class="form-control" [(ngModel)]="model.name" name="name" #name="ngModel" required>
        <div [hidden]="name.valid || name.pristine" class="alert alert-danger">
      Employee ID is required
        </div>
  </div>
  <div class="form-group">
    <label for="DOJ">DOJ</label>
    <input class="form-control" required [(ngModel)]="model.DOJ" name="DOJ" #DOJ="ngModel"  />
    <div [hidden]="DOJ.valid || DOJ.pristine" class="alert alert-danger">
      DOJ is required
    </div>
  </div>
  <button type="submit" class="btn btn-default" [disabled]="!myForm.form.valid">Submit</button>
</form>

以下是我的问题.

EXCEPTION: Template parse errors:
       There is no directive with "exportAs" set to "ngModel" ("
         <div>
          <h1>My Form</h1>
             <form (ngSubmit)="onSubmit()" [ERROR ->]#myForm="ngModel">

我已经检查了更多的问题和答案,他们中的大多数都说将angular2版本更新为RC4,所以我已经将我的应用程序更新为rc4,但我仍然面临这个问题.

以下是我的ts文件：

import {Component} from '@angular/core';
import { disableDeprecatedForms,provideForms,NgForm} from '@angular/forms';
import {CORE_DIRECTIVES,FORM_DIRECTIVES,FormBuilder,Validators,Control,ControlGroup } from '@angular/common';


@Component({
selector: 'ej-app',templateUrl: 'app/app.component.html',directives: [ CORE_DIRECTIVES,FORM_DIRECTIVES]  
})
  export class AppComponent {
  model = new Employees(null,'','');
    onSubmit() { alert("values submitted")}
   constructor() {
     }
     }
        export class Employees {
         constructor( public id: number,public name: string,public DOJ: String ) {  }
}
