mongoose中键值对的正确语法是什么？

Question

var schema = new Schema({
    firstName: {type: String, required: true},
    lastName: {type: String, required: true},
    password: {type: String, required: true},
    email: {type: String, required: true, unique: true},
    polls: [{type: Schema.Types.ObjectId, ref: 'Poll'}]
    /*This is incorrect*/votes: [{{type: Schema.Types.ObjectId, ref: 'Poll'},{type: number}}]
});

Answer 1

要为votes字段提供有意义的结构，请使用对象数组而不是值对（在Mongoose中无法严格定义）：

votes: [{
    poll: {type: Schema.Types.ObjectId, ref: 'Poll'},
    count: {type: number}
}]
