typescript - 如何使用 typescript 正确创建表格

Question

我正在尝试这样做:

interface UserI {
    id?: number | null,
    name: string,
    password: string
}


@Table(
    {
        tableName: 'user',
        timestamps: true
    }
)
class User extends Model implements UserI{

    @AutoIncrement
    @PrimaryKey
    @Column(INTEGER)
    id!: number

    @AllowNull(false)
    @NotEmpty
    @Column(STRING)
    name!: string

    @AllowNull(false)
    @NotEmpty
    @Column(STRING)
    password!: string

}

但不断报错:TypeError: Class constructor Model cannot be invoked without 'new';
我究竟做错了什么？

Answer 1

import { Model, Column, Table, AutoIncrement, PrimaryKey, NotEmpty, AllowNull } from "sequelize-typescript";

@Table(
    {
        tableName: 'user',
        timestamps: true
    }
)
export class User extends Model<User>{
    @AutoIncrement
    @PrimaryKey
    @Column
    id!: number

    @AllowNull(false)
    @NotEmpty
    @Column
    name!: string

    @AllowNull(false)
    @NotEmpty
    @Column
    password!: string
}

不需要接口(interface)。
