手稿错误：私人财产丢​​失？

Question

我有一个私人性质的一类，但是当我尝试创建这个元素，我得到以下错误的数组：

error TS2322: Type '{ "id": number; "totalTime": number; "team": { "id": number; "name": string; }; }[]' is not assignable to type 'Training[]'. 
[0] Type '{ "id": number; "totalTime": number; "team": { "id": number; "name": string; }; }' is not assignable to type 'Training'. 
[0]  Property 'remainingTime' is missing in type '{ "id": number; "totalTime": number; "team": { "id": number; "name": string; }; }' 

Array类：

import { TEAMS } from './mock-teams'; 
import { Training } from './training'; 

export var TRAININGS: Training[] = [ 
    {"id": 0, "totalTime": 60, "team": {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] } }, 
    {"id": 1, "totalTime": 60, "team": {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] } } 
]; 

培训等级：

export class Training { 
    private remainingTime: number = 0; 

    constructor(
     public id: number, 
     public totalTime: number, 
     public team?: Team) { 
    } 
} 

我不明白为什么打字稿抱怨私人财产，即使不在构造函数中。

你的方式，你正在创建一个类型为对象[]的数组。你需要做的是调用像下面的构造函数告诉你正在创建一个转译器培训对象：

import { TEAMS } from './mock-teams'; 
import { Training } from './training'; 

export var TRAININGS: Training[] = [ 
    new Training(0,60, {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] }), 
    new Training(1,60, {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] }) 
];
