import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { EventDetail } from '../../models/event-detail/event-detail.interface';
import { AngularFireDatabase, AngularFireList } from 'angularfire2/database';
@IonicPage()
@Component({
selector: 'page-event',
templateUrl: 'event.html',
})
export class EventPage {
eventDetail = {} as EventDetail;
eventDetailRef$: AngularFireList<EventDetail[]>;
constructor(public navCtrl: NavController, public navParams: NavParams, private database: AngularFireDatabase) {
this.eventDetailRef$ = this.database.list('event-detail');
}
addEvent( eventDetail: EventDetail) {
this.eventDetailRef$.push({
eventName: this.eventDetail.eventName,
eventDesc: this.eventDetail.eventDesc,
});
}
}
我在一年前遵循了一个教程,我推荐了“升级到Angularfire 5.0”,用谷歌搜索了同样的问题,结果却大不相同
错误消息是:
“类型'{eventName:string; eventDesc:String;}'的参数不能分配给'EventDetail []'类型的参数。 对象文字只能指定已知属性,并且'EventName'在'EventDetail []'类型中不存在。”
和我的EventDetail界面:
export interface EventDetail {
eventName: string;
eventDesc: String;
lat: number;
lgt: number;
}

错误消息表明您正在尝试将{ eventName: string; eventDesc: String; }
分配给EventDetail
push
方法需要一个数组,而不是单个实例。

将eventDetailRef$: AngularFireList<EventDetail[]>;
更改为eventDetailRef$: AngularFireList<EventDetail>
因为您的类型是Array<Array>
,并且您试图推送单个项目
