mongodb - 请教Mongoose嵌套数据Schema定义问题？

Question

请问下这样的数据应该如何定义Schema，怎么用push操作List数组？

我想大声告诉你 · Answer

If the outermost List can be changed to an array, it can be defined in the following way

const childChildSchema = new mongoose.Schema({
    PlayerID: Number,
    Msg: String,
    Time: Date
});
const childSchema = new mongoose.Schema({
    PlayerID: Number,
    ReadLast: Date,
    List：[childChildSchema]
});
const parentSchema = new mongoose.Schema({
    ID: Number,
    List: [childSchema]
});
