类型'match'的参数不能分配给any []类型的参数-nodejs/mongoose [英] Argument of type 'match' is not assignable to parameter of type any[] - nodejs / mongoose

问题描述

我的查询在RoboMongo中运行良好，但是当我在nodeJs环境中构造相同的查询时，就会出现异常.

My query is running fine in RoboMongo, but when I construct the same in my nodeJs environment I'm getting the exception.

下面是我的代码

存储库功能

public find = async (account: any): Promise<any> => {
  return PromoTypes.aggregate(
    {
      $match: { account: { $in: account } }
    },
    {
      $group: {
        _id: '$account',
        data: {
          $push: { _id: '$_id', description: '$description', iteration: '$iteration' }
        }
      }
    }
  );
};

服务文件调用了上述仓库.功能

AccountService.ts

public accountService = async (accountid: string): Promise<any> => {
 //accounttypes is an array constructed to pass to the repo, it has more business logic about construction which I have not included in this code. But the object would be as below

 accounttypes = ["first,second"]
 let accountDetails = await AccountRepo.find(accounttypes);
}

下面是我得到的错误.

 Argument of type '{ $match: { account: { $in: any; }; }; }' is not assignable to parameter of type 'any[]'.   Object literal may only specify known properties, and '$match' does not exist in type 'any[]'.ts(2345)

我尝试过的事情

我尝试将Promise类型更改为以下类型

I tried changing the promise type to below types

 1. public accountService = async (accountid: string): Promise<any[]> =>{
 2. public accountService = async (accountid: string): Promise<Array<Object>> => {
 3. public accountService = async (accountid: string): Promise<Object> => {

以上方法均无法解决该问题.

None of the above approaches work for fixing the issue.

推荐答案

您需要将数组传递给aggregate管道

you need to pass an array to the aggregate pipeline

public find = async (account: any): Promise<any> => {
  return PromoTypes.aggregate([
    {
      $match: { account: { $in: account } }
    },
    {
      $group: {
        _id: '$account',
        data: {
          $push: { _id: '$_id', description: '$description', iteration: '$iteration' }
        }
      }
    }
  ]);
};
