Cast error inserting array (embedded documents) using Mongoose?

[Ryan Kelly]

I have tried multiple ways to do this, all resulting in an error. I have checked, and double checked Mongoose documentation and examples so I must be doing something wrong. I want to be able to insert 1-to-many contacts (Contact.js) into an array of contacts ([Contact]) for a given venue (Venue.js).

It seems like I should be able to do this:

// contact model

var mongoose = require('mongoose')

   ,Schema = mongoose.Schema

   ,ObjectId = Schema.ObjectId;

 

var contactSchema = new Schema({    

  firstName  : { type: String, required: true, trim: true },

  lastName  : { type: String, required: true, trim: true },

email    : { type: String, required: true, trim: true },

created : {type: Date, default: Date.now}

});

 

module.exports = mongoose.model('Contact', contactSchema);

// venue model

var Contact = require('./contact.js'); 

var mongoose = require('mongoose')

   ,Schema = mongoose.Schema;

var venueSchema = new Schema({   

_id     : { type: String, required: true, trim: true },

name     : { type: String, required: true, trim: true },  

description     : { type: String, required: true, trim: true },

market : { type: String, required: true, trim:true }, // key to Market.js

state : { type: String, required: true, trim:true }, // key to State.js

isActive : { type: Boolean, required: false, default: false },

siteUrl     : { type: String, required: false, trim: true },

contacts : [{ type: Contact, required: true, trim:true }], // array of Contact.js

privateNotes    : { type: String, required: false, trim: true },   

    comments : { type: String, required: false, trim: true },

    coverImage : { type: String, required: true, trim: true },

    images : { type: String, required: false, trim: true }

});

 

module.exports = mongoose.model('Venue', venueSchema);

// venues.js

exports.addVenue = function(req, res) {

  var v = req.params;

  venueExists(v, function(exists) {

      if (exists) { 

        return res.send(new restify.ConflictError("Venue already exists"));

      } else {

        var venue = new Venue({

          _id      : string(v.name).slugify().s, // need to replace space with _ and make lowercase

          name          : v.name,  

          description   : v.description,

          isActive      : v.isActive,

          siteUrl       : v.siteUrl,

          market        : v.market,       // key to Market.js

          state         : v.state,        // key to State.js

          contacts      : v.contacts      // array of objects (Contact.js)

          privateNotes  : v.privateNotes,   

          comments      : v.comments,

          coverImage    : v.coverImage,

          images        : v.images

        });

        venue.save(function (err) {

          if (!err) {

            return res.send(201, venue);

          } else {

            return res.send(err);

          }

        });

      }

  });

}

It returns a casting error:

"message": "Cast to undefined_method failed for value \"[object Object],[object Object]\" at path \"contacts\""

any thoughts?

Here is the sample payload I'm passing in:

{

  "name":"my venue",

  "description":"my description",

  "isActive":true,

  "siteUrl":"http://google.com",

  "market":"resort",

  "state":"CO",

  "contacts": [

        {

            "firstName": "Mike",

            "lastName": "Ditka",

          "email": "mi...@gmail.com"

        },

        {

            "firstName": "Dick",

            "lastName": "Butkus",

          "email": "di...@gmail.com"

        }

    ],

  "privateNotes":"my notes",

  "comments":"my comments",

  "coverImage":"default.png",

  "images":"myImage.png"

}

Some things to try:

1) In order to treat a contact as an embedded document in venue you need to export the contact schema from contact model, not the model

2) In venue model you would specify an array of embedded contact documents using "contacts: [contactSchema]"

that worked! I swear I thought I tried that but apparently not. Thanks Daniel!

Here is my new venue model.

// venue model 

var mongoose = require('mongoose')

   ,Schema = mongoose.Schema;

var contactSchema = new Schema({    

  firstName  : { type: String, required: true, trim: true },

  lastName  : { type: String, required: true, trim: true },

email  : { type: String, required: true, trim: true },

created  : {type: Date, default: Date.now}

});

var venueSchema = new Schema({   

_id     : { type: String, required: true, trim: true },

name     : { type: String, required: true, trim: true },  

description     : { type: String, required: true, trim: true },

market : { type: String, required: true, trim:true }, // key to Market.js

state : { type: String, required: true, trim:true }, // key to State.js

isActive : { type: Boolean, required: false, default: false },

siteUrl     : { type: String, required: false, trim: true },

contacts : [contactSchema], // array of Contact.js
