Mongoose - 如何使这些数据更有用？
我在节点/express 应用程序中从我的架构中输出以下数据结构。我想让 feeds 数组只是一个名称：密钥对的数组。我不喜欢“提要”和实际提要数据之间发生的那种奇怪的编号对象结构。但我不知道如何在猫鼬中手动定义它。任何帮助都会很棒。谢谢！
输出 JSON
{
"title": "Testing",
"created_at": "2011-10-05T16:23:26.217Z",
"feeds": [{
"0": {
"name": "twitter",
"key": "person1"
},
"1": {
"name": "twitter",
"key": "person2"
},
"_id": "4e8c847e02edc10035000003"
}]
}
我想要这个：
{
"title": "Testing",
"created_at": "2011-10-05T16:23:26.217Z",
"feeds": [
{
"name": "twitter",
"key": "person1"
},
{
"name": "twitter",
"key": "person2"
}
],
"_id": "4e8c847e02edc10035000003"
}
这是我的架构：
var Feed = new Schema({
name : { type: String }
, key : { type: String }
});
var Page = new Schema({
title : { type: String, required: true, index: { unique: true } }
, feeds : [Feed]
, created_at : { type: Date, required: true, default: Date.now }
});
I have the following data strucutre outputting form my Schema in a node/express app. I'd like to have the feeds array simply an array of name:key pairs. I don't like the sort of weird numbered object structure going on between "feeds" and the actual feeds data. But i can't figure out how to manually define that in mongoose. any help would be awesome. thanks!
outputted JSON
{
"title": "Testing",
"created_at": "2011-10-05T16:23:26.217Z",
"feeds": [{
"0": {
"name": "twitter",
"key": "person1"
},
"1": {
"name": "twitter",
"key": "person2"
},
"_id": "4e8c847e02edc10035000003"
}]
}
i want this:
{
"title": "Testing",
"created_at": "2011-10-05T16:23:26.217Z",
"feeds": [
{
"name": "twitter",
"key": "person1"
},
{
"name": "twitter",
"key": "person2"
}
],
"_id": "4e8c847e02edc10035000003"
}
this is my schema:
var Feed = new Schema({
name : { type: String }
, key : { type: String }
});
var Page = new Schema({
title : { type: String, required: true, index: { unique: true } }
, feeds : [Feed]
, created_at : { type: Date, required: true, default: Date.now }
});

好的，一位同事能够帮我回答这个问题。我很遗憾没有发布相关代码，我没有意识到问题实际上出在哪里。但对于那些可能遇到此问题的人来说：
如果在保存时将嵌入式文档推送到模型中，则可能需要执行 forEach 循环，而不是将嵌入式文档（在本例中为 Feed）推送到一起。使用 forEach，数据库将提要直接保存到提要数组中，而不是创建那些奇怪的分组。
这正确地推送了提要：
如果您有同样的问题并且需要更多解释，请告诉我。
Ok, a colleague was able to answer this for me. My bad for not posting the relevant code, I didn't realize where the problem actually was. But for those who may encounter this problem:
If you push your embedded docs into the model when saving, you may need to do a forEach loop rather than pushing the embedded docs (in this case Feeds) together. Using forEach, the database saved the feeds directly to the feeds array rather than creating those weird groupings.
This pushed the feeds in properly:
Let me know if you have the same problem and need more explanation.
