javascript - Mongoose populate - Node.JS creating multiple objects -

-

task have make array of i.e. dishes logged user selecting favourite. problem instead of 1 array of objectids i.e. dishes:[123456,5678910], 2 separate objects same user 1 dish id in array.

i presume problem in schema, can give me idea?

var favoriteschema = new schema({  timestamps: true,   dishes: [{     type: mongoose.schema.types.objectid,     ref: 'dish' }],  postedby: {     type: mongoose.schema.types.objectid,     ref: 'user' }  });

edit>> post method demanded

.post(verify.verifyordinaryuser, function (req, res, next) { favorites.create(req.body, function (err, favorite) {     if (err) throw err;     console.log('favorite created!');     var id = favorite._id;     favorite.postedby = req.decoded._doc._id;     favorite.dishes.push(req.body);     favorite.save(function (err, favorite) {         if (err) throw err;         console.log('updated favorites!');         res.json(favorite);     }); });

your post method fine first time want add favorite dish. next time add dish same user should call

favorites.findone({postedby: req.decoded._doc._id}, function (err, favorite) {   favorite.dishes.push(req.body);   favorite.save(function (err, favorite) {         if (err) throw err;         res.json(favorite);     }); })
