【问题描述】：

一直在尝试使用 Mongoose findByIdAndUpdate 按 ID 更新文档，操作运行没有错误，但更改未反映在数据库上。

在服务器日志上，我只能看到 users.findOne 在我运行 API 时记录，猫鼬也不应该同时运行更新。我可以毫无问题地获取/创建/删除用户。

界面

export interface User {
  _id: string;
  email: string;
  password: string;
}

型号

const userSchema: Schema = new Schema({
  email: {
    type: String,
    required: true,
    unique: true,
  },
  password: {
    type: String,
    required: true,
  },
});

控制器

public updateUser = async (req: Request, res: Response, next: NextFunction) => {
    try {
      const userId: string = req.params.id;
      const userData: CreateUserDto = req.body;
      const updateUserData: User = await this.userService.updateUser(userId, userData);

      res.status(200).json({ data: updateUserData, message: 'updated' });
    } catch (error) {
      next(error);
    }
  };

服务

  public async updateUser(userId: string, userData: CreateUserDto): Promise<User> {
    if (isEmpty(userData)) throw new HttpException(400, "You're not userData");

    if (userData.email) {
      const findUser: User = await this.users.findOne({ email: userData.email });
      if (findUser && findUser._id != userId) throw new HttpException(409, `You're email ${userData.email} already exists`);
    }

    if (userData.password) {
      const hashedPassword = await bcrypt.hash(userData.password, 10);
      userData = { ...userData, password: hashedPassword };
    }

    const updateUserById: User = await this.users.findOneAndUpdate({ _id: userId }, { userData }, { new: true });
    if (!updateUserById) throw new HttpException(409, "You're not user");

    return updateUserById;
  }

dtos

import { IsEmail, IsString } from 'class-validator';

export class CreateUserDto {
  @IsEmail()
  public email: string;

  @IsString()
  public password: string;
}

在我运行更新 API 时记录

【解决方案1】：

更新不起作用，因为您将{ userData } 作为更新参数传递给findOneAndUpdate()。这相当于 { userData: userData } 并且不适合您的架构。要解决它，您只需要稍作改动即可：

const updateUserById: User = await this.users.findOneAndUpdate({ _id: userId }, userData, { new: true });
