角度模型中的对象声明/关系

Question

有可能这样做吗我想在我的模型中声明一个对象，我尝试的第一个是

export class Employee{
emp_id: number;
emp_fname: string;
emp_lname: string;
emp_birth: string;
emp_status: string;
emp_photo: string;
emp_department: string; 
department: Array<object> = 
[{
dept_id: number;
dept_name: string;
}];

第二个像这个

import { Department } from "./department.model";
export class Employee{
constructor(department: Department){};
emp_id: number;
emp_fname: string;
emp_lname: string;
emp_birth: string;
emp_status: string;
emp_photo: string;
emp_department: string; 
department: department;
}

我的终端中的两个返回错误：第一个返回expects，但当我这样做时，它说我应该使用eg:number作为类型，而不是值。

然后第二个返回错误

找不到名称"department"。

我的部门型号

export class Department {
dept_id: number;
dept_name: string;
}

Answer 1

export class Department {
dept_id: number;
dept_name: string;
constructor(dept_id, dept_name){
this.dept_id = dept_id;
this.dept_name = dept_name;
}
}
export class Employee{
emp_id: number;
emp_fname: string;
emp_lname: string;
emp_birth: string;
emp_status: string;
emp_photo: string;
emp_department: string; 
department: Department[] = [new Department(1, "dept_name1"), new Department(2, "dept_name2")];
}
