如何在猫鼬中填充许多模式

请在这里给我解决方案我打算编写一个共享搜索查询的通用函数，我使用mongodb + mongoose，

但是有一个我不知道如何动态使用pupulate（）的问题。

例如：

const findData = async(model, populate, params) => {
   return await model
      .find(params)
      .populate() //issue????
};

我想填充许多其他模式，但仍然找不到将填充填充到此功能的方法（即：我可以在调用此功能时通过它传递的模式）？谢谢你建议我非常感谢

Please give me the solution here
I'm planning to write a common function to share for search queries, I use MongoDB + Mongoose

But there is a problem that I don't know how to dynamically use populate().

Ex:

const findData = async(model, populate, params) => {
   return await model
      .find(params)
      .populate() //issue????
};

I want to populate to many other Schemas but still can't find a way to pass populate to this function dynamically (ie: I can populate to the Schema it is passed in when calling this function)?
Thank you for suggesting me
Many thanks

您可以在一个数组中收集所有填充命令，并在每个人查询中召集并使用。

const findData = async(model, populate, params) => {

const popQuery = [];
if(req.query = "example1") {
popQuery.push({path:"user" , select: "name"})
}
if(req.query = "example2") { 
popQuery.push({path:"model2" , select: "name lastName age"})
}
if(req.query = "example3") {
popQuery.push({path:"model3" , select: "everything"})
}

   return await model
      .find(params)
      .populate(popQuery) //issue????
};

you can collect all populate command in one array and called in .populate and use if for everyone query and add push new command in your array and all of them send your array of populate in your mongoose query like :

const findData = async(model, populate, params) => {

const popQuery = [];
if(req.query = "example1") {
popQuery.push({path:"user" , select: "name"})
}
if(req.query = "example2") { 
popQuery.push({path:"model2" , select: "name lastName age"})
}
if(req.query = "example3") {
popQuery.push({path:"model3" , select: "everything"})
}

   return await model
      .find(params)
      .populate(popQuery) //issue????
};
