blocks|key|2123662|text|最佳实践是将任何动态数据从字段名中删除。这种用例的典型方法是使groups成为一个数组，并将组的名称移动到包含对象的name字段中。然后可以使用Mixed类型来包含用户定义的一组值：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2123663|{

});|2123666|entityMap^0|V|6|1M|4|20|5|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

Best practice is to keep any dynamic data out of your field names. The typical approach for a use case like this is to make <code>groups</code> an array and move the name of the group into a <code>name</code> field of the contained objects. Then you can use the <code>Mixed</code> type to contain the user-defined set of values:

<pre><code>{
 "_id": ObjectId("..."),
 "groups":
 [
 {
 name: "groupA",
 values: {
 "value1": "...",
 "value2": "..."
 }
 },
 {
 name: "groupB",
 values: {
 "value3": "..."
 }
 },
 {
 name: "groupC",
 values: {
 "value4": "...",
 "value5": "..."
 }
 },
 ...
 ]
}
</code></pre>

You'd define the schema as:

<pre><code>var schema = new Schema({
 groups: [{
 name: String,
 values: Schema.Types.Mixed
 }]
});
</code></pre>

Have you tried something like this:

<pre><code>var schema = new mongoose.Schema({
 groups: [mongoose.Schema.Types.Mixed]
});
</code></pre>

Reference: <a href="http://mongoosejs.com/docs/schematypes.html" rel="nofollow">Mongoose Schema Types</a>

Edit, given my comments below, and riffing on the answer before mine, let's assume that all values are of type string (I had understood that they might be anything):

<pre><code>var schema = new mongoose.Schema({
 groups:[{
 name: String,
 values:[String]
 }]
});
</code></pre>

Edit #2: Assuming that "value1" is a placeholder for some more meaningful name and assuming that the number of member names is finite, as long as they are not required, then you can put them all in your schema, so instead of the array version, you should be able to do this:

<pre><code>var schema = new mongoose.Schema({
 groups:[{
 name: String,
 value1: String,
 value2: String,
 value3: String,
 value4: String,
 value5: String
 }]
});
</code></pre>

Map is supported from version 5.1 - 
<a href="http://mongoosejs.com/docs/schematypes.html#maps" rel="noreferrer">http://mongoosejs.com/docs/schematypes.html#maps</a>

I'm trying to create a schema in Mongoose that have a map (object, associative array, key-value pairs), but no success so far. 
The documents of my schema must be something like this:

<pre><code>{
 "_id": ObjectId("..."),
 "groups"
 {
 "groupA":
 {
 "value1": "...",
 "value2": "..."
 },
 "groupB":
 {
 "value3": "...",
 },
 "groupC":
 {
 "value4": "...",
 "value5": "...",
 },
 ...
 }
}
</code></pre>

groups is as object with a variable number of keys. I don't know those keys ahead of time as it'll be create by the user. 
Every entry in groups is another object. As before, I don't know the key identifiers, but I know that the values are String (or Boolean, or Number, doesn't matter). 
Of course, those keys are Strings.

Is it even possible (is there anyway to build such schema/model) in Mongoose?

我试图在Mongoose中创建一个模式，它有一个映射(对象、关联数组、键值对)，但到目前为止还没有成功。我的模式的文档必须如下所示：{    "_id": ObjectId("..."),    "groups"    {        "groupA":        {            "value1": "...
