我的对象数组中具有以下数据结构：

[{
event: string,
day: string,
player: {
    first: string,
    last: string,
    email: string
},
waivers: [{
    url: string,
    signatureUrl: string,
    email: string,
    message: string
}],
_id: {
  id: objectID,
  email: string
},
...]

在我的组件中，我想过滤数据，以便显示三个不同的东西：

this.dummies将过滤结果以显示player.email为dummypartner@pottstown.com的所有记录
unsigned将通过豁免数组的has_signed属性过滤结果。应该将其设置为false
signed应该通过嵌套数组豁免的has_signed属性等于true

this.adminService.GetUnsignedWaivers()
.subscribe((data: []) => {
   this.dummies = data.filter(x => {
      return x.player.email === "dummypartner@pottstown.com";
   });
this.unsigned = data.filter(x => {
   x.waivers.filter(w => {
      return w.has_signed === false;
   });
});
this.signed = data.filter(x => {
   x.waivers.filter(w => {
      return w.has_signed === true;
   });
});
this.players = data;
this.players.forEach((p) => {
   p.waivers = p.waivers.map( w => {
      if (w.signatureUrl.length > 0) {
         w.url = w.signatureUrl;
         w.message = "View Waiver";
      }
      return w;
   });
});

我试图使以上内容显示为代码，但无法正常工作！：（

我的初始查询的结果显示得很好，但是过滤后的数据的计数并没有在控制台中显示和记录为未定义。

我该怎么做？

编辑后添加console.log数据：

看着这个，我可以理解为什么它可能不起作用，但是我不知道如何在我的聚合中对豁免进行分组，因此值不在数组中（因为它们不是数组，而是字符串）。

我的后端聚合查询：

    Registration.aggregate([
      {$unwind: "$players"},
    {$unwind:"$players.waivers"},
    {$lookup:{
      from:"waiverrecipients",
      localField: "players.waivers",
      foreignField:"_id",
      as:"waivers"
    }},
    {$group: 
      {
        "_id":{"id": "$_id","email": "$players.email"},
        "buyer": {"$first": "$users"},
        "event": {"$first": "$event"},
        "field": {"$first": "$field"},
        "net": {"$first": "$net"},
        "team": {"$first": "$team"},
        "player": { "$first": "$players" },
        "waivers": {"$push":{
          "url": "$waivers.url",
          "message": "$waivers.message",
          "has_signed": "$waivers.has_signed",
          "signatureUrl": "$waivers.signatureUrl",
          "email": "$waivers.email"
        } }}},
    {$sort: 
      {
        "event": 1,
        "_id.id": 1,
        "_id.email": 1,
  }}
  ])

Answer 1

如果只需要过滤后的数组和计数，则可以使用data对forEach数组进行一次迭代，并检查每个条件，如果满足条件，则推入适当的数组。这样便得到了三个过滤后的数组，并且可以对其中的任何一个调用.length方法来获取计数。

// app.component.ts

let players: any[] = [];
let dummies: any[] = [];
let unsigned: any[] = [];
let signed: any[] = [];

this.adminService.GetUnsignedWaivers().subscribe((data: any[]) => {
  data.forEach(x => {
    if (x.player.email === 'dummypartner@pottstown.com') {
      dummies.push(x);
    }

    x.waivers.forEach(waiver => {
      if (waiver.has_signed[0] === true) {
        signed.push(waiver);
      } else {
        unsigned.push(waiver);
      }

      if (waiver.signatureUrl.length > 0) {
        waiver.url = waiver.signatureUrl;
        waiver.message = "View Waiver";
      }
    }); // waiver forEach
  }); // data forEach

  this.players = data;
}); // subscribe

如果您想使用filter方法：

// app.component.ts

let players: any[];
let dummies: any[];
let unsigned: any[] = [];
let signed: any[] = [];

this.adminService.GetUnsignedWaivers().subscribe((data: any[]) => {
  let updatedData = data.map(x => {
    x.waivers.forEach(waiver) {
      if (waiver.signatureUrl.length > 0) {
        waiver.url = waiver.signatureUrl;
        waiver.message = "View Waiver";
      }
    });
    return x;
  }); // map

  this.dummies = updatedData.filter(x => {
    x.player.email === 'dummypartner@pottstown.com';
  }); // filter

  updatedData.forEach(x => {
    unsigned = unsigned.concat(x.waivers.filter(w => !w.has_signed[0]));
    signed = signed.concat(x.waivers.filter(w => w.has_signed[0]));
  }); // forEach

  this.players = updatedData;
}); // subscribe

请注意，由于您使用的是材料表，因此可以添加带有少量代码的过滤器：

<!-- app.component.html -->

<mat-form-field>
  <input matInput (keyup)="applyFilter($event.target.value)" placeholder="Filter">
</mat-form-field>

// app.component.ts

applyFilter(filterValue: string) {
  this.dataSource.filter = filterValue.trim().toLowerCase();
}

this.dummies将过滤结果以显示玩家的任何记录。dummypartner@ pottstown.com的电子邮件
unsigned将通过放弃数组的has_signed属性过滤结果。应该设置为false
signed应该通过嵌套数组放弃的has_signed属性等于true来过滤结果

代码

this.dummies = data
  .filter(item => item.player.email === 'dummypartner@pottstown.com');

this.unsigned = data
  .filter(item => item.waivers.some(waiver => !waiver.has_signed));

this.signed = data
  .filter(item => item.waivers.some(waiver => !!waiver.has_signed));

这足以满足您的需求。我不明白为什么您编写了这么多复杂的代码！

Answer 3

在您的组件代码中，要过滤的内容与数据结构本身不匹配。例如：

this.dummies = this.data.filter((x: any) => {
  // `x` does not have a `player` property based on `this.data` structure
  // The same holds true for all other filter predicates in the file
  return x.player.email === "dummypartner@pottstown.com";
});

第二次尝试的问题在于如何过滤数据...

this.unsigned = data.filter(x => {
  x.waivers.filter(w => {
    return w.has_signed === false;
});

外部过滤器函数不返回，因此返回值为undefined，根据JS标准为false-y。您的unsigned数组始终为空，因为无论如何过滤谓词都会返回false-y语句。

此外，您的数据结构不包含has_signed的定义。您确定它总是存在吗？如果数据对象中不存在has_signed，则w.has_signed为undefined，并且w.has_signed === false返回false。您可以选择不使用类型安全比较（==而不是===），或者通过返回!w.has_signed使用JS隐式类型转换功能。

因此，我将像这样重新进行过滤（将相同的逻辑应用于signed过滤）：

// If you want all objects from `data` where at least one object from `wavers` has not signed
this.unsigned = data.filter(x => x.waivers.some(w => !w.has_signed));
// ^^ With no curly braces the result of the single statement is also the return value

// If you want all the objects from `waivers` with false-y `has_signed`
this.unsigned = data.reduce((x, acc) => [...acc, ...x.waivers.filter(w => !w.has_signed)], []);

对于最后一部分，不建议对已经存储在其他位置的数据进行突变。我建议对对象进行浅表复制，如下所示：

this.players = data.map(p => ({
  ...p,
  waivers: p.waivers.map(w => 
    w.signatureUrl.length > 0
      ? { ...w, url: w.signatureUrl, message: "View Waiver" }
      : w
  )
}));

希望这会有所帮助！：-）

我用Express和Mongo创造了这种情况。我已插入数据并进行了简单查询。像这样：

function getPlayers(req, res) {
    ObjectModel.find( (err, data)  => {
        if ( err ) {
            return res.status(500).send({
                message: err
            });
        }
        return res.status(200).send({
            data
        });
    })

}

您必须修改服务以返回数组：

  GetUnsignedWaivers() {
    return this.http.get<any>(this.url + '/getPlayers').pipe(
      flatMap( data => data.data ),
      toArray()
    );
  }

因此，您保证您拥有一系列物品。然后，您可以订阅：

this.adminService.GetUnsignedWaivers().subscribe( (data) => {
      this.dummies = data.filter(item => {
        if (item.player) {
          return item.player.email === 'dummypartner@pottstown.com';
        } else {
          return false;
        }
      });
      data.forEach( (item, idx) => {
        let flag = false;
        if (item.waivers) {
          item.waivers.forEach(x => {
            if (!x.has_signed[0]) {
              flag = true;
            }
          });
          if (flag) {
            this.unsigned.push(item);
          } else {
            this.signed.push(item);
          }
        }
      });
      console.log(this.dummies);
      console.log(this.unsigned);
      console.log(this.signed);
    });
