角度为2 rc5的基于模型的形式不起作用

我现有的代码是这样的

profile.ts

import {FORM_DIRECTIVES,REACTIVE_FORM_DIRECTIVES} from '@angular/forms';
import {FormBuilder,FormGroup,FormControl,Validators} from '@angular/forms';

 this.firstName = new FormControl();
        this.lastName = new FormControl();
        this.email = new FormControl();
        this.addressLine = new FormControl();
        this.postal = new FormControl();
        this.postalArea = new FormControl();

        this.form = builder.group({
            firstName: this.firstName,lastName: this.lastName,email: this.email,addressLine: this.addressLine,postal: this.postal,postalArea: this.postalArea,photo: this.photo
        });

和profile中的模板.HTML如下

<form class="form-default"  [formGroup]="form">

<input type="text" class="form-control" id="firstName" [(ngModel)]="model.firstName" formControlName="firstName" maxlength="200">

    <input type="text" class="form-control" id="lastName" [(ngModel)]="model.lastName" formControlName="lastName" maxlength="200">
    <input type="text" class="form-control" id="email" [(ngModel)]="model.username" readonly formControlName="email" maxlength="100">

    </form>

我在控制台中遇到以下错误.

EXCEPTION: Error: Uncaught (in promise): EXCEPTION: Error in
/assets/scripts/my-profile/my-profile.html:176:66 ORIGINAL EXCEPTION:
ngModel cannot be used to register form controls with a parent formGroup directive. Try using
formGroup’s partner directive “formControlName” instead. Example:
