Mongodb 查找比较数组元素到数组字段

Question

I'm wondering how I can compare arrays of (nested) objects in Mongoose.

Considering the codebelow, I would like to get results when the pskills properties match. Could anyone help me with this?

  ao = await Ao.find({
//req.body.pSkills is arraay //['nodejs', 'angular'..]
                pSkills: { $eq: req.body.pSkills }
          });

Answer 1

You have to use $in to search into an array.

Try this query:

ao = await Ao.find({
  "pSkills": {
    "$in": req.body.pSkills
  }
})
