无法将 ref id 发布到父集合 mongoDB

Question

Im trying to insert two records into mongoDB. One as a new collection the other a ref id.

Sample of schema Company{ name: Acme Company, Locations: [refID] }

the id & location payload will be sent in the body of the request.

 addNewLocation: (req, res) => { let {id, ...payload} = req.body; db.Location.create(payload).then( record => { let refId = record._id db.Company.findOneAndUpdate( {_id: id}, { $push: { locations: refId } }, { new: true }) }).then( result => { res.status(201).json({success: true},{result}) }).catch( err => { res.status(422).json({success: false},{err}) }) }

when viewing the update (on Robo3T) it appears to be inserting a document into the location, but it doesn't insert the ref id in the companies collection. Any ideas what might be causing this?

Answer 1

Probably you mistake locations spelling case when you want to push ref It may be Locations as you schema filed name or change your schema field to locations . You can try by this in your company schema

 {
    name: String,
    locations:[
      {
      type: Schema.Types.ObjectId,
      ref: "Location"
     }
    ]
 }

Answer 2

createNewLocation: (req, res) => {
    let { companyId , ...payload } = req.body;

    db.Location.create(payload)
    .then(({_id}) => {
       return db.Company.findOneAndUpdate(companyId, {$push:{location: _id}},{new: true})
    })
    .then(()=>{
        res.status(201).json({success: true})
    })
    .catch((err)=>{
        res.status(422).json({success: false})
    })
}

Here is the solution, just needed a return.
