Many ObjectId objects in Mongoose

Question

My document contains a field called clients , which should contain an array of client identifiers.

 { "first_name":"Nick", "last_name":"Parsons", "email":" [e-mail] ", "password":"foo", "clients":[ "50f5e901545cf990c500000f", "50f5e90b545cf990c5000010" ] } 

My data comes in as JSON, and I send it directly to Mongo to create the document. For some reason, clients do not populate when I create, so I need to manually enter them as strings.

My scheme is quite simple and is defined as:

 var userSchema = new Schema({ first_name: { type: String, trim: true }, last_name: { type: String, trim: true }, email: { type: String, trim: true, lowercase: true, index: true, unique: true, required: true }, password: String, clients: [Schema.Types.ObjectId] }); 

From my point of view, I correctly identified customers. But I can not get the array of clients to fill when I do the creation. The event raw object that is passed in mongo looks good.

 { first_name: 'Zack', last_name: 'S', email: ' [e-mail] ', password: 'test', clients: [ '50f5e901545cf990c500000f', '50f5e90b545cf990c5000010' ] } 

Is there anything special I have to do with my input so that it runs correctly?

Accepted answer may be outdated ...

If you are going to update this collection, I would recommend using the $ push update. This update method is designed to prevent updates when everything you do is added to the array in the collection.

Simple fix. Checking the filling of the incoming array. If so, I iterate over each of them and insert the converted version of ObjectId into the array. Apparently mongoose.Types.ObjectId('STRING'); can convert a common string to a valid mongoose identifier.

 // if clients was passed with associated client ids if (data.clients.length > 0) { _.map(data.clients, function(cid) { // push client id (converted from string to mongo object id) into clients user.clients.push(mongoose.Types.ObjectId(cid)); }); } 

Hope this helps someone else.
