推荐答案

适用于那些在将表单从 Angular 2 RC 1(或更早版本)迁移到 Angular 2 RC 2/RC 4 New Forms 时遇到问题的人.以下是他们需要遵循的步骤:

For those who are having trouble in migrating forms from Angular 2 RC 1 (or earlier) to Angular 2 RC 2 / RC 4 New Forms. Here are the steps they need to follow:

通过将以下包添加到它们的 packages.json 中，在您的项目中包含新表单:

Include new forms in your project by adding below package to their packages.json:

"@angular/forms": "0.2.0",

接下来，他们必须在主文件中禁用已弃用的表单并包含如下所示的新表单:

Next, they have to disable the deprecated forms in main file and include new forms something like below:

import {disableDeprecatedForms, provideForms} from '@angular/forms';
bootstrap(AppComponent, [
   disableDeprecatedForms(),
   provideForms()
])

然后在他们的组件中为新的表单指令添加导入:

Then in their component add import for new form directives:

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

为组件包含 REACTIVE_FORM_DIRECTIVES:

Include REACTIVE_FORM_DIRECTIVES for the component:

directives: [REACTIVE_FORM_DIRECTIVES],

在您的组件中重命名以下内容:

In your component rename the following:

ControlGroup > FormGroup
Control > FormControl

在您的模板中重命名以下内容:

In your templates rename the following:

ngFormModel > formGroup
ngControl > formControlName

我希望这会有所帮助.
