TypeORM v0.3.12 按照文档里写的，报错 No metadata for "Auth" was found.

Question

import {
	Column, ManyToOne, JoinColumn,
	Entity, PrimaryGeneratedColumn
} from "typeorm";
import { User } from "./user";

@Entity({ name: "auths" })
export class Auth {
    @PrimaryGeneratedColumn() readonly id!: number;
    @Column() user_id!: string;
    @Column() type!: string;
    @Column() identifier!: string;
    @Column() credential!: string;
    @ManyToOne(() => User, { cascade: true })
    @JoinColumn({ name: "user_id" }) user!: User;
}

import "reflect-metadata";
import { DataSource } from "typeorm";
import { ConnectionOpts } from "@/scripts/config";
import { User } from "./entity/user";
import { Auth } from "./entity/auth";

const entities = [User, Auth];
const options = { ...ConnectionOpts, entities };
const AppDataSource = new DataSource(options);
export default AppDataSource;

import AppDataSource from "@/database";
import { User } from "@/database/entity/user";
import { Auth } from "@/database/entity/auth";
import { tSession } from "@/scripts/types";

async function login(req: NextApiRequest, res: NextApiResponse) {
    const { type, mobile, verify } = req.body;
    const userRepository = AppDataSource.getRepository(User);
    const authRepository = AppDataSource.getRepository(Auth);
    const session: tSession = req.session;
    
    if (session.verifyCode === verify) {
        const condition = { type, identifier: mobile };
        // 运行到这个查找语句，就报错：No metadata for "Auth" was found.
        const authRes = await authRepository.findOneBy(condition);
    }
}

查了下资料，说是通常因为实体没有正确的定义、导入或注册引起的。
但是我看了好几遍，没看出什么问题来。不知道怎么办，求老师指导。

[Auth, User]

Auth 表里面有用 user 信息，你在 entity 注册那里调整一下它俩的顺序试试呢

  刚刚试了下，不行的。之前出问题的时候，换成在用户表里查找 const userRes = await userRepository.findOneBy(condition); 就会报错 No metadata for "User" was found.

  刚刚又去看了下文档，发现那些数据库操作，要放在它的函数里执行才可以。
  AppDataSource.initialize().then(async () => {
      const condition = { type, identifier: mobile };
      const authRes = await authRepository.findOneBy(condition);
  }).catch(error => console.log(error));
  文档里的示例都比较简单，不知道是不是每次做数据库操作都要套一下

  嗯嗯 最近工作太忙了，抽时间我也看下哈
