使用 NestJS 注入 ObjectionJS 模型抛出异常

Injecting ObjectionJS model using NestJS throws exception

当我尝试将 Objection.js 模型注入 NestJs 服务时:

constructor(@Inject('UserModel') private readonly modelClass: ModelClass<UserModel>) {}

我在编译时遇到 Maximum call stack size exceeded 错误。我认为这是由于我的其他模型和一些循环依赖。我删除了一个单独模型之外的所有内容,但仍然出现异常。

如果我在 tsconfig.json 中设置 "strict": true,代码将按预期构建和运行。我该如何补救这种情况?

以下是使用的型号和封装。

基础模型

export default class BaseModel extends Model {
  readonly id: number;
  createdBy: number;
  created!: string;
  modified: string;
  modifiedBy: number; 
}

用户模型

export default class UserModel extends BaseModel {
  static tableName = 'users';
  static virtualAttributes = ['fullName'];

  firstName!: string;
  lastName!: string;
  company?: string;
  email!: string;

  fullName(): string {
    return `${this.firstName} ${this.lastName}`;
  }


  static jsonSchema = {
    type: 'object',
    required: ['firstName', 'lastName', 'email'],
    properties: {
      id: { type: 'number' },
      firstName: { type: 'string' },
      lastName: { type: 'string' },
      company: { type: 'string' },
      email: { type: 'string' },
    },
  };
}

According to this issue Typescript 必须在 strict 模式下 运行 才能 运行 正确拼写代码。似乎 Objection v3 仍处于某种预发布状态,因此还没有完整记录。
