猫鼬使用查询获取多个集合数据

Question

我正在尝试加入两个猫鼬集合并使用我在下面提到的查询获取所有相关详细信息。问题是当我调用 GetEmployeeDetails(emp_id) 时，我只得到一个 table 详细信息 employee collection 无法得到两个集合详细信息。需要一个建议。如何一次查询得到两个集合数据

const EmployeeInfoSchema = mongoose.Schema({
  employee_id: String,
  client_id: {
    type: Schema.Types.Number,
    ref: "client",
  },
  email: String,
  contact: String,
});

const ClientInfoSchema = mongoose.Schema({
  client_id: Number,
  employee_id: {
    type: Schema.Types.String,
    ref: "employee",
  },
  project: String,
  organization: String,
});

let employeeInfo = mongoose.model("employee", EmployeeInfoSchema);
let clientInfo = mongoose.model("client", ClientInfoSchema);

module.exports = { employeeInfo, clientInfo };

查询

async function GetEmployeeDetails(emp_id) {
  let employee_info = await Storage.employeeInfo
    .find()
    .where({ employee_id: emp_id })
    .populate({
      path: "client",
    })
    .exec(function (err, block) {
      if (err) {
        console.log("%s", err);
      }
      console.log("Employee details is %s", employee_info);
    });

  return employee_info;
}

尝试像这样更改您的 GetEmployeeDetails 方法：

async function GetEmployeeDetails(emp_id) {
  try {
    let employee_info = await Storage.employeeInfo
      .find({ employee_id: emp_id })
      .populate('client')
      .exec(function (err, block) {
        if (err) console.log('%s', err);
        else console.log('Employee details is %s', employee_info);
      });

    return employee_info;
  } catch (err) {
    res.status(400).send('Error getting details');
  }
}
