Question

我在mongodb有一组乐队数据和用户。 我想做的是：乐队数据包含诸如'band: band 1', 'band: band 2', 'band: band 3'之类的数据。（还有其他数据，但是我写了我想使用的东西）。

我希望用户在注册时输入频段数据，以找出注册时用户所在的频段。 显示数据时：如果频段数据等于频段，我希望用户显示磁带。我想执行某种过滤过程。我想以这种方式进行上市。你能帮忙吗？

通过这种方式，我列出了乐队数据：

refreshLineList() {
  this.lineService.getLineList().subscribe(res => {
      this.lineService.lines = res as Line[]; //Line = band data
      console.log(res);
  });
}

要吸引用户数据：

ngOnInit() {
    this.refreshLineList();
    this.userService.getUserProfile().subscribe(
      res => {
        this.userDetails = res['user'];
        console.log(res);
      },
      err => {
        console.log(err);
      }
    );
  }

用户的控制台输出：

> {status: true, user: {…}}
status: true 
user:
 bant: "Bant 1"  // **this is the part I should use in my filter**
 email: "e@e.com" > 
>  fullName: "esra"
> __proto__: Object
> __proto__: Object

将乐队数据输出到控制台：

(4) [{…}, {…}, {…}, {…}]
0:
bant: "Bant 1"  // **this is the part I should use in my filter**
