提问by TIMEX

Let's say I have a model called User. I have an array with object Ids.

假设我有一个名为User. 我有一个带有对象 ID 的数组。

I want to get all User records that "intersect" with the array of Ids that I have.

我想获得所有与我拥有的 Id 数组“相交”的用户记录。

User.find({ records with IDS IN [3225, 623423, 6645345] }, function....

Here is a mongoosey way to use the $in operator.

这是使用 $in 运算符的猫鼬方式。

User.find()
  .where('fb.id')
  .in([3225, 623423, 6645345])
  .exec(function (err, records) {
    //make magic happen
  });

I find the dot notation quite handy for querying into sub documents.

我发现点符号对于查询子文档非常方便。

For example:

例如:

Users.find( { "fb" : { id: { $in : arrayOfIds } } }, callback );

For me, work this way

对我来说,这样工作

IDs=["5b00c4b56c7fb80918293dd9","5b00c4b56c7fb80918293dd7",...]
const users= await User.find({records:IDs}) 

回答by SnnSnn

Ids is the array of object ids:

Ids 是对象 ID 的数组:

const ids =  [
    '4ed3ede8844f0f351100000c',
    '4ed3f117a844e0471100000d', 
    '4ed3f18132f50c491100000e',
];

With callback:

带回调:

User.find().where('_id').in(ids).exec(callback);

With async function:

具有异步功能:

records = await User.find().where('_id').in(ids).exec();
