angular - Firestore : Add Custom Object to db

Question

早上好

我试着从这个类中添加一个新创建的对象:

export class Sponsor implements ISponsor {

  title: string;    
  description?: string;
  creation: ICreation;

  constructor(title: string, description: string, author: string) {
     this.title = title;
     this.description = description;
     this.creation = new Creation(author);
  }
}

在我的服务中，创建函数如下所示:

createSponsor(sponsor) {
   sponsor.id = this.afs.createId();
   return this.collection.doc(sponsor.id).set(sponsor);
}

当我以这种方式尝试时，出现以下错误:

FirebaseError: [code=invalid-argument]: Function DocumentReference.set() called with invalid data. Data must be an object, but it was: a custom Sponsor object

我该如何解决这个问题？

Answer 1

你也可以使用 Object.assign({}, sponsor)

所以在你的情况下会是

this.collection.doc(sponsor.id).set(Object.assign({}, sponsor));
