Question

目前mogo通过mongoose的数据如下。一旦我把它从mongo中拉出来，我希望能够迭代选项。目前，如果我将此记录保存到变量“记录＆＃34;。我需要做record.options [0] .option1.check，我想避免[0]。我希望能够迭代一个对象并能够执行以下操作。 record.option1.choice1 record.option2.choice2

my schema is 
    var questionSchema = new mongoose.Schema({
    question: String,
    question_slug: String,
    options: []
});



    {
        "_id" : ObjectId("5832609483bf491db3d8faa1"),
        "question" : “What is the capital of Illinois?",
        "question_slug" : “what-is-the-capital-of-illinois",
        "options" : [
                {
                        "option1" : {
                                "check" : "on",
                                "choice" : “Springfield"
                        },
                        "option2" : {
                                "check" : "",
                                "choice" : “Chicago"
                        }
                }
        ],
        "__v" : 0
}

Answer 1

您无法定义record.option1.choice1和record.option2.choice2的架构，因为option1和option2似乎是动态的。

但您可以通过[0]而不是record.options[0].option1.check将options定义为Object来避免schema array。

因此，您可以使用record.options和record.options.option1等迭代对象record.options.option2。

var questionSchema = new mongoose.Schema({
    question: String,
    question_slug: String,
    options: {
       type: Object
    }
});



{
    "_id" : ObjectId("5832609483bf491db3d8faa1"),
    "question" : “What is the capital of Illinois?",
    "question_slug" : “what-is-the-capital-of-illinois",
    "options" : {
                    "option1" : {
                            "check" : "on",
                            "choice" : “Springfield"
                    },
                    "option2" : {
                            "check" : "",
                            "choice" : “Chicago"
                    }
    },
    "__v" : 0

}

Mongoose对象模式：如何在mongoosejs中声明模式以便能够迭代选项字段？
