How To Create Mongoose Schema with Array of Object IDs?
If you want to use Mongoose populate feature, you should do:
var userSchema = mongoose.Schema({
email: { type: String, required: true, unique: true},
password: { type: String, required: true},
name: {
first: { type: String, required: true, trim: true},
last: { type: String, required: true, trim: true}
},
phone: Number,
lists: [listSchema],
friends: [{ type : ObjectId, ref: 'User' }],
accessToken: { type: String } // Used for Remember Me
});
exports.User = mongoose.model('User', userSchema);
This way you can do this query:
var User = schemas.User;
User
.find()
.populate('friends')
.exec(...)
You'll see that each User will have an array of Users (this user's friends).
And the correct way to insert is like Gabor said:
user.friends.push(newFriend._id);
I'm new to Mongoose myself, so I'm not entirely sure this is right. However, you appear to have written:
friends: [mongoose.Types.ObjectId],
I believe the property you're looking for is actually found here:
friends: [mongoose.Schema.Types.ObjectId],
It may be that the docs have changed since you posted this question though. Apologies if that's the case. Please see the Mongoose SchemaTypes docs for more info and examples.
I would try this.
user.friends.push(newFriend._id);
or
friends: [userSchema],
but i'm not sure if this is correct.
