如何使数据在Angular 2中的详细页面中可见？

后端

我使用Django RestFrame实现了一个多概念，我的输出如下

前端

在前端，我能够检索除tax_详细信息之外的所有数据。它只是作为这样一个对象返回。

事实上，我对这个概念还不太熟悉，所以我不知道如何克服它

Html

<div class="row">
  <div class="col-md-12">
    <nb-card>
      <nb-card-header>
        <span>Product Details</span>

这里我提到了我的Html、Component.ts和输出图像，所以请告诉我如何获取这些数据

错误2

您面临的错误是什么？tax_details是一个对象数组，因此您看到的输出是正确的。您希望在表中输出什么？是。我期待着喜欢的名字和它的百分比应该显示在Html详细页面。尝试后，我得到了一个错误，就像我上传了上面的图片。感谢回复。尝试后，它也抛出错误，我上传了上面的图像。图像名称（错误2）
constructor(private themeService: NbThemeService,
              private route: ActivatedRoute,
              private breakpointService: NbMediaBreakpointsService,
              private service: ProductsService,
              private router: Router) {

    this.breakpoints = this.breakpointService.getBreakpointsMap();
    this.themeSubscription = this.themeService.onMediaQueryChange()
      .subscribe(([oldValue, newValue]) => {
        this.breakpoint = newValue;
      });
      this.route.params.subscribe(
        params => {
          this.user = params['id'];

        });


          this.service.get_update(this.user).subscribe(update => this.update = update,
                                                        error => console.log(error));


          this.service.get_updatetax(this.user).subscribe(update1 => this.update1 = update1,
                                                      error => console.log(error));

 this.update=([])
 this.update1=([])

  }

<div class="detail font-w-light">
   <div *ngFor="let el of update.tax_details"</div>
     <p> {{el.name}} {{el.percentage}} </p>
</div>
