angularfire2，仅将数据推送/更新到特定的子/密钥

Question

我有一个推送数据的功能，另外两个属性必须被推送/更新/存储到同一个键。有percentMale和percentFemale。我需要将这两个属性的提交结果放在同一个子/键中。我们说密钥是L2Jq0Tg4JOS66F786pT。

male: number = 0;
female: number = 0;
percentMale;
percentFemale;
insertdata(data: App) {
  if (data.data1 == 'Male') {
    this.male++;
  } else if (data.data1 == 'Female') {
    this.female++;
  }
  this.percentMale = this.male / (this.male + this.female) * 100;
  console.log('percentMale', this.percentMale + '%');

  this.percentFemale = this.female / (this.male + this.female) * 100;
  console.log('percentFemale', this.percentFemale + '%');

  this.dataList.push({
    data1: data.data1,
    data2: data.data2,
    data3: data.data3,
    time: new Date().getTime(),
  });

  this.dataList.push({
    percentMale: this.percentMale,
    percentFemale: this.percentFemale,
  });

  //if a key already exist
  //this.dataList.update(data.$key, {
  //percentMale: this.percentMale,
  //percentFemale: this.percentFemale,
  //});
}

我所做的功能导致更多percentMale和percentFemale分开存储，表格显示不必要的行。

有人能帮我解决这个问题吗？如果需要更多的片段，请告诉我。

      percentMale: this.percentMale,
      percentFemale: this.percentFemale,
