带有Sequelize的NestJS Crud模块

Question

[我在github上发现了这个Crud Module，我认为这很棒，但是我想将其与续集一起使用。按照nestjs docs与seqeulize一起使用，我创建了这样的服务：

@Injectable()
export class CompaniesService extends RepositoryService<Company> {
  protected options: RestfulOptions = {};

  constructor(
    @Inject('CompaniesRepository') private readonly companiesRepository: typeof Company,
  ) {
    super();
  }
}

我想做的是在初始化时将companiesRepository传递给RepositoryService，但是我是Typescript的新手，所以我不知道companiesRepository的类型是什么。RepositoryService类是这样的：

import { Model } from 'sequelize-typescript';
import { Provider } from '@nestjs/common';
import { RestfulService } from '../classes/restful-service.class';

export class RepositoryService<T extends Model<T>> extends RestfulService<T> {
  protected options: RestfulOptions = {};

  constructor(protected model: Provider) {
    super();
  }
}

我不确定protected model: Provider部分，因为我无法调用模型函数，例如create，findAll，findOne ...

感谢您的任何帮助。

同样有问题！

Model not initialized: Member "findAll" cannot be called. "Products" needs to be added to a Sequelize instance.
