Matching nested array of nested subdocuments in MongoDB

Question

I am trying to create a query, that matches two criteria. Match a specific userId and match a range of Id's.

An example document could look like this:

I have tried with using find by adding the userId and then using the MongoDB $in operator to match a list of feature (as an id)

  const featureIds = features.map(feature => feature._id)
    console.log(featureIds)
    const isFeatureExists = await this.userShopModel.find({
      userId,
      'items.feature': { $in: featureIds },
    })
    console.log(isFeatureExists)

I have also tried with different versions of aggregate but without any luck.

Any mongo experts, who can help me?

Answer 1

use _id for filter

const featureIds = features.map(feature => feature._id)
    console.log(featureIds)
    const isFeatureExists = await this.userShopModel.find({
      _id : userId,
      'items.feature': { $in: featureIds },
    })
    console.log(isFeatureExists)
