问题描述
早上好
我尝试从此类添加一个新创建的对象:
I tried adding a new created object from this class:
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,创建功能如下:
and in my service, the create function looks like:
createSponsor(sponsor) {
sponsor.id = this.afs.createId();
return this.collection.doc(sponsor.id).set(sponsor);
}
以这种方式尝试时,出现以下错误:
When I try it this way, I get the following error:
FirebaseError:[code = invalid-argument]:使用无效数据调用的函数DocumentReference.set().数据必须是一个对象,但是它是:一个自定义的发起人对象
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?
How can I solve this issue?
推荐答案
您也可以使用Object.assign({},Sponsor)
You can also use Object.assign({}, sponsor)
所以在您的情况下应该是
so in yor case it would be
this.collection.doc(sponsor.id).set(Object.assign({}, sponsor));
