Angular 如何使用For loop从Mat单选组中获取选定的单选按钮值

我有一个复杂的物体，如下图所示

someName = [
{name: "John",id: "1",rating: ['0', '1', '2', '3', '4', '5']},
{name: "robert", id: "2", rating: ['0', '1', '2', '3', '4', '5']},
{name: "luv", id: "3", rating: ['0', '1', '2', '3', '4', '5']}
];

<ng-container *ngFor="let sort of someName; let i=index">
   <label id="example-radio-group-label">Rate your favorite section</label>
   <mat-radio-group aria-labelledby="example-radio-group-label" class="example-radio-group" [(ngModel)]="sectionRating">
      <mat-radio-button class="example-radio-button" *ngFor="let section of sort.sections" [value]="section">{{season}}</mat-radio-button>
   </mat-radio-group>
</ng-container>

从中我想做一个调查问卷，以确保他们从0-5分评价他们的答案，现在当我呈现我的html时，如下图所示

someName = [
{name: "John",id: "1",rating: ['0', '1', '2', '3', '4', '5']},
{name: "robert", id: "2", rating: ['0', '1', '2', '3', '4', '5']},
{name: "luv", id: "3", rating: ['0', '1', '2', '3', '4', '5']}
];

<ng-container *ngFor="let sort of someName; let i=index">
   <label id="example-radio-group-label">Rate your favorite section</label>
   <mat-radio-group aria-labelledby="example-radio-group-label" class="example-radio-group" [(ngModel)]="sectionRating">
      <mat-radio-button class="example-radio-button" *ngFor="let section of sort.sections" [value]="section">{{season}}</mat-radio-button>
   </mat-radio-group>
</ng-container>

您可以尝试使用

（change）

事件，然后在局部变量中添加click项

HTML代码：

<ng-container *ngFor="let sort of someName; let i=index">
    <label id="example-radio-group-label">Rate your favorite section</label>
    <br>
    {{sort.name}}
    <br>
    <mat-radio-group aria-labelledby="example-radio-group-label" class="example-radio-group">
        <mat-radio-button class="example-radio-button" *ngFor="let section of sort.rating" [value]="section"
            (change)="radioChange($event,sort)">
            {{section}}</mat-radio-button>
    </mat-radio-group>
    <br>
    <br>

</ng-container>

<h2>Selected Array</h2>
<div>
   {{finalArray | json }}
</div>

您可以使用一个布尔属性来选中取消选中radio按钮，但我需要每个部分分别评级，并且somename对象中可以有n个对象。是否可以创建stackblitz？我从您的（@prashant）解决方案中找到了解决方法，非常感谢。
