Angular 2 RC6 Forms control validation message - 


<form [formgroup]="registerform" (submit)="onsubmit()">     <label>firstname:</label>     <input type="text" formcontrolname="firstname">     <p *ngif="registerform.controls.firstname.errors">this field required!</p> ...

is there way make registerform.controls.firstname.errors little bit shorter?

one way define shorter names abstractcontrol properties in form component. in respective component class, add:

firstname: abstractcontrol;

and in constructor:

this.firstname = this.registerform.controls['firstname'];

now, can access field properties this:

<p *ngif="firstname.errors">this field required!</p>
