Недавно я обновил свой angular2 проект 2.0.2 версии, когда я использую входные тег я получил следующую ошибку,Angular2: ngModel не может быть использован для регистрации элементов управления формой с материнской formGroup директивой
Ошибки,
Uncaught (in promise): Error: Error in app/articles/articles.html:42:20 caused by:
ngModel cannot be used to register form controls with a parent formGroup directive. Try using
formGroup's partner directive "formControlName" instead. Example:
<div [formGroup]="myGroup">
<input formControlName="firstName">
</div>
In your class:
this.myGroup = new FormGroup({
firstName: new FormControl()
});
Мой шаблон,
<div *ngIf = 'showform'>
<form class="nobottommargin" [formGroup]="form" (ngSubmit)="onSubmit(form.value)" novalidate="novalidate">
<div class="form-process"></div>
<div class="col_full">
<label for="template-contactform-name">Title</label>
<input type="text" formControlName="articletitle" placeholder="Title" class="sm-form-control required" aria-required="true">
</div>
<div class="clear"></div>
<div class="col_full">
<label for="template-contactform-message">Description</label>
<textarea class="required sm-form-control" formControlName="articledescription" placeholder="Description" rows="6" cols="30" aria-required="true"></textarea>
</div>
<div class="clear"></div>
<div class="col_full">
<label >Tags</label>
<tag-input [ngModel]="['@item']"
[autocompleteItems]="['Item1', 'item2', 'item3']"
[autocomplete]="true">
</tag-input>
<div class="col_full">
<button class="button button-3d nomargin" type="submit" id="template-contactform-submit" name="template-contactform-submit" value="submit">Save</button>
</div>
</form>
</div>
Мой компонент,
this.form = new FormGroup({
articletitle: new FormControl(''),
articledescription: new FormControl(''),
tags: new FormControl('')
});
ngModule.ts,
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { Category } from './categories/category';
import { Login } from './login/login';
import { Mainapp } from './components/app.component';
import { Topics } from './topics/topics';
import { SignUp } from './signup/signup';
import { Articles } from './articles/articles';
import { Article } from './article/article';
import { User } from './user/user';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';
import { TagInputModule } from 'ng2-tag-input';
import { App } from './tags/tags';
// import { TagInputModule } from 'ng2-tag-input';
// import {Ng2TagsInputModule} from 'ng2-tagsinput';
@NgModule({
imports: [ BrowserModule, ReactiveFormsModule,FormsModule,TagInputModule,HttpModule,
RouterModule.forRoot([
{ path: '', component:Login },
{ path: 'login', component:Login },
{ path: 'signup', component: SignUp },
{ path: 'categories', component: Category },
{ path: 'topics/:id', component: Topics },
{ path: 'articles/:id', component: Articles },
{ path: 'article/:id', component: Article },
{ path: 'user', component: User },
{ path: 'app', component: App },
])],
declarations: [ Mainapp,App,Login,SignUp,Category,Topics,Articles,Article,User ]
,bootstrap: [ Mainapp ]
})
export class AppModule { }
Я не уверен, что ошибка о, кто может предложить помощь.
Какой компонент является «tag-input»? Откуда вы его взяли? –
Я получил это от ngModule, ts file – MMR
