如何在另一个ngFor表中正确编写NgModel表单

public formValues: any[] = [];

<div *ngFor="let item of formValues; let i = index">
  <input type="text" [(ngModel)]="formValues[i].value">
</div>

public formValues: { field1: string, field2: string }[] = [];

<div *ngFor="let item of formValues; let i = index">
  <input type="text" [(ngModel)]="formValues[i].field1">
  <input type="text" [(ngModel)]="formValues[i].field2">
</div>

public addForm(): void {
  this.formValues.push({ field1: '', field2: '' });
}

<button (click)="addForm()">Add Form</button>
