是否有正确的方法将相同的数据文档添加到 firestore 中的两个不同集合中？

Question

以下代码将数据插入 firestore 中的 'doctors' 集合。但是我想将相同的数据记录同时添加到同一个 firestore 数据库中另一个名为 'next' 的集合中。

service.ts

create_Newdoctor(Record){
  return this.firestore.collection('doctors').add(Record);
}

component.ts

CreateRecord(docForm: NgForm){
  let Record = {};
  Record['fullName']=this.fullName;
  Record['email']=this.email;
  Record['gender']=this.gender;
  Record['role']="doctor";

  this.DoctorService.create_Newdoctor(Record).then(res=> {
    this.fullName="";
    this.email="";
    this.gender="";
    console.log(res);
        this.message = "New doctor added";
  }).catch(error=>{
    console.log(error);
  });
}

能不能提前告诉我一个办法this.Thank你

Answer 1

const collections = ["doctors", "next"];

create_Newdoctor(Record, collections) {
  const promises = collections.map(collectionName =>
    this.firebase.collection(collectionName).add(Record)
  );

  return Promise.all(promises);
}
