understanding mongoose [Schema.Types.Mixed]

Question

Is the below schema represented correctly or does the script need to be writing: [Schema.Types.Mixed] or writing: [{}]?

What I mean if you have an array of dictionaries -- [{},{},{}] -- one can't predefine the inner structure unless you create another schema and embed it. Is that the right analysis of the docs?

http://mongoosejs.com/docs/schematypes.html

var blogSchema = new mongoose.Schema({

  title:  String,

  writing: [{

        post: String,

        two: Number,

        three : Number,

        four  : String,

        five : [{  a: String,

                    b : String,

                    c  : String,

                    d: String,

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

                }]

  }],

});

Yes, your structure is accurate. Stating an object within an array schema/structure element is considered as its Schema object. With that being said, the schema object will have their individual id field, but you can disable those id fields by explicitly defining the schema with the _id option being disabled:

var blogSchema = new mongoose.Schema({title: String, writing: [new Schema({post: String, two: Number, three : Number, four  : String, five : [new Schema({ a: String, b: String, c: String, d: String, e: { type: Date, default: Date.now }, }, {_id: false})], {_id: false})], });
