使用Mongoose在Mongo DB中存储对象的Javascript数组

Question

I have an array of the form [{key: ..., type: ..., value: ...}] and want to store it in the fields field in the following schema:

var articleSchema = mongoose.Schema({
  name: {
    type: String,
    unique: true,
    required: true
  },
  updated: {
    type: Date,
    default: Date.now
  },
  pageviews: {
    type: Number,
    default: 0
  },
  fields: [{
    key: String,
    type: String,
    value: String
  }],
  image: String
});

I am doing this as follows, my Javascript array referenced as keyValueObj

Article.findOneAndUpdate(
  { name: articleName },
  {
    fields: keyValueObj
  },
  { upsert: true },
  callback
);

However, all that is stored in the database in the fields field is an array of strings like this: ["[object Object]"]

How can I store my Javascript array so that it matches my mongoose schema correctly?

Answer 1

I was able to fix this using Molda's idea of using a separate schema.

The updated fields field in the articleSchema now looks like this:

fields: [{
  type: Schema.Types.ObjectId,
  ref: 'Field'
}]

I then converted the array to an array of schema objects, like this:

keyValueObj = keyValueObj.map(function(fieldObj){
  return new Field({
    key: fieldObj.key,
    type: fieldObj.type,
    value: fieldObj.value
  });
});

I was then able to store keyValueObj the was doing it in the initial code.
