Push element to array in mongoose

Question

I am trying to push an element to an array in mongoose. I am doing it with update and $push. But it is not updating it in the database. This is my code. routes.js:

Answer 1

This is how you can update a model in mongoose (using async await) :

let updatedModel = await Model.findByIdAndUpdate(req.params.id,

 { $push: { accounts:{"name": "foo", "idAccount": 123456} } },

 { 'upsert': true });

or in your code

Maybe you have missed the {new: true, upsert: true } if you want the updated document to be returned to you.

Chooser.update({_id: req.params.id}, {$push: {accounts: {"name": "foo", "idAccount": 123456}}},{new: true, upsert: true });

We are doing it this way - we are adding another model but in your case your just adding an array so put that in a variable and in place of req.body.resource ..

Also you can just use findByIdAndUpdate not the Async if you don't want to.

here is the model element:

 resources: [{type: mongoose.Schema.Types.ObjectId, ref: 'Resource'}],

here is the method to add an item to the array:

//AddResource to a crew
export function addResource(req, res) {
  if (req.body._id) {
    delete req.body._id;
  }
  Crew.findByIdAndUpdateAsync(req.params.id,
    {
      $push: { "resources": req.body.resource }
    },
    { safe: true, upsert: true },
    function (err, model) {
      if (err) {
        //console.log(err);
        return res.send(err);
      }
      return res.json(model);
    });

and to remove:

//deleteResource to a crew
export function deleteResource(req, res) {
  if (req.body._id) {
    delete req.body._id;
  }
  // console.log(req.body.resource);
  Crew.findByIdAndUpdateAsync(req.params.id,
    {
      $pullAll: { "resources": req.body.resource }
    },
    function (err, model) {
      // console.log(model);
      if (err) {
        //console.log(err);
        return res.send(err);
      }
      return res.json(model);
    });

We can do like that

Model.findOneAndUpdate({"_id":req.body.id},{
            "$push": {"resources": req.body.resources}
        },{new: true, safe: true, upsert: true }).then((result) => {
            return res.status(201).json({
                status: "Success",
                message: "Resources Are Created Successfully",
                data: result
            });
        }).catch((error) => {
            return res.status(500).json({
                status: "Failed",
                message: "Database Error",
                data: error
            });
        });`

As far as I know, you have to do as below.

Model.findAndUpdate({_id: 'your_id'}, 
                    {$push: {'your_array_field': 
                    {"name": "foo","idAccount": 123456}}}, 
                    {new: true}, (err, result) => {
                    // Rest of the action goes here
                   })
