我有一个非常基本的项目:
https://github.com/napolev/ionic-start
基本上是Ionic
入门项目:
// https://ionicframework.com/getting-started
$ ionic start ionic-start tabs
我添加了以下两个文件:
/src/extras/social-media.ts
import * as Promise from 'bluebird';
import { User } from './user';
export var LoginPromise = function(service): Promise<string> {
return new Promise((resolve) => {
setTimeout(function(){
resolve('Will Smith');
}, 2000)
});
};
//*/ IF I COMMENT THIS BLOCK OUT, THERE IS NO ERROR
// this function is not used by this project
// but for some specific reasons it is required to be here
// this code is a simplification of a bigger project
export var callMeIfYouNeedMe = function(id) {
return new Promise((resolve) => {
User.findById(id, function(err, user) {
console.log(user);
resolve(user);
});
});
}
// END OF BLOCK */
/src/extras/user.ts
import { Document, Schema, Model, model} from "mongoose";
export interface IUser {
name: string;
}
export interface IUserDocument extends IUser, Document {
}
export var UserSchema: Schema = new Schema({
name: String,
});
export const User: Model<IUserDocument> = model<IUserDocument>("User", UserSchema);
上面的代码在节点项目上可以正常工作(我自己尝试过)。我是从http://brianflove.com/2016/10/04/typescript-declaring-mongoose-schema-model/#schema--model获得的 在上一次导出时,我创建了一个类型为
IUserDocument
的模型。
我还修改了以下两个文件:
/src/pages/home/home.ts
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { LoginPromise } from '../../extras/social-media';
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(public navCtrl: NavController) {
}
test() {
console.log('Hello World');
LoginPromise('facebook').then(
(name: string) => {
console.log('### Social Media -> ' + name);
}
);
}
}
/src/pages/home/home.html
<ion-header>
<ion-navbar>
<ion-title>Home</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<h2>Welcome to Ionic!</h2>
<p>
This starter project comes with simple tabs-based layout for apps
that are going to primarily use a Tabbed UI.
</p>
<p>
Take a look at the <code>src/pages/</code> directory to add or change tabs,
update any existing page or create new pages.
</p>
<button ion-button (click)="test()" color="primary">Test</button>
</ion-content>
我的问题是,当我跑步时:
$ ionic serve --no-open
我在控制台上没有收到任何错误,但是在浏览器上我得到了以下信息:
"Runtime Error: Object(...) is not a function"
如您所见:
您对这里可能发生的事情有什么想法,我怎么做?
谢谢!
答案 0 :(得分:0)
运行时错误:Object(…)不是函数
您的通话:
model<IUserDocument>("User", UserSchema);
是错误的。 model
不是函数。它是一个对象。
不调用一个对象。代码错误。
