mongoose Foreign Key

Question

I have a model called Portfolio that points to a user object using the user_id field. How can I model a many to one relationship with mongoose?

Portfolio - user_id => is the id of a user object

Basically every portfolio object belongs to a user object.

I have the following code: Is this correct?

var PortfolioSchema = mongoose.Schema({
    url: String,
    createTime: { type: Date, default: Date.now },
    updateTime: { type: Date, default: Date.now },
    user:[
      {type: Schema.Types.ObjectId, ref: 'User'}
    ]
});

Answer 1

Try this instead

var PortfolioSchema = mongoose.Schema({
    url: String,
    createTime: { type: Date, default: Date.now },
    updateTime: { type: Date, default: Date.now },
    user:{type: Schema.Types.ObjectId, ref: 'User'}
});
