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:

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);
    });
