如何从集合中调用数据

Question

此代码我调用集合，但我想调用集合中的所有数据

export class RepairService {
    Reqref: AngularFirestoreCollection < ServiceRepair > ;
    constructor(private db: AngularFirestore, public ngFireAuth: AngularFireAuth) {
        this.Reqref = db.collection('iygR4pP0ZDXxBlFmzUMxAeqKtkt1', ref => ref.where("Title", "==", "Service & Repair"));
    }

Answer 1

要从集合中加载所有数据，请从 collection 调用中删除查询：

this.Reqref = db.collection('iygR4pP0ZDXxBlFmzUMxAeqKtkt1');

或者：

this.Reqref = db.collection('iygR4pP0ZDXxBlFmzUMxAeqKtkt1', ref => ref);
