How to use “await” in sails when creating a new record

Question

I want to use "await"

According to the sails documentation I act as follows:
https://sailsjs.com/documentation/reference/waterline-orm/models/create

create: function (req, res, next) {

var new_place = await Place.create({...}, function place_created(err, XX){

  if(err && err.invalidAttributes) {
    return res.json({'status':false, 'errors':err.Errors});
  } 
}).fetch();
if(new_place){
  console.log(new_place);
  res.json({'status':true,'result':new_place});
 }
},  

But I get the following Error:

var new_place = await Place.create({...}, function place_created(err, XX){
                ^^^^^
SyntaxError: await is only valid in async function  

what should I do to fix this.

Answer 1

SyntaxError: await is only valid in async function

This is because you are using await in a function that is not async

Remember, the await keyword is only valid inside async functions. If you use it outside of an async function's body, you will get a SyntaxError.

Source MDN async function

You need to make the function async for it to work. Making those changes in your code,

'use strict';

create: async function(req, res, next) {
        var new_place = await Place.create({ ... }, function place_created(err, XX) {
            if (err && err.invalidAttributes) {
                return res.json({ 'status': false, 'errors': err.Errors });
            }
        }).fetch();
        if (new_place) {
            console.log(new_place);
            res.json({ 'status': true, 'result': new_place });
        }
    },

Answer 2

I think you should make your function async.

 async(function(){
   var new_place = await Place.create({...})
})();

And if you are using await you should not use callbacks. You should manage the response as explained here
