MongoMapper 带有自定义用户数据的动态EmbeddedDocument
我有一个名为 LogInfo 的 MongoMapper 模型，它已经定义了许多字段（：user_id、：user_key、：message 等）
但是，我还希望用户将自己的 JSON 对象嵌入为 EmbeddedDocument。
有没有办法在 MongoMapper 中使用匿名对象创建自定义对象？我是否必须求助于本机 Ruby 驱动程序？最终对象看起来像这样：
{
user_id: 393,
user_key: "kdIekHG32Je",
message: "Application error",
custom_data: {
browser: "Firefox 8.0",
location: {
lat: 34.323,
lon: -14.091
}
}
}
其中 custom_data 字段是应用程序用户可以提供的随机内容。
I have a MongoMapper model called LogInfo that has a number of fields already defined (:user_id, :user_key, :message, etc)
However, I'd also like the user to embed their own JSON objects as an EmbeddedDocument.
Is there a way to use anonymous objects to create a custom object in MongoMapper? Would I have to resort to the native Ruby driver instead? The final object would look something like this:
{
user_id: 393,
user_key: "kdIekHG32Je",
message: "Application error",
custom_data: {
browser: "Firefox 8.0",
location: {
lat: 34.323,
lon: -14.091
}
}
}
where the custom_data field is something random the app user can provide.

当然。您不必求助于 Ruby 驱动程序。
MongoMapper 通过调用将对象转换为 MongoDB 表示：
to_mongo方法已经为一堆标准类定义，您也可以为自己的类定义它。请参阅 lib/mongo_mapper/extensions 了解所有具有 < code>to_mongo 定义并 http://mongomapper.com/documentation/types.html 有关自定义类型的文档。但是，如果您满足于让用户只给您一个哈希值，那么它就会起作用。
Sure. You don't have to resort to the Ruby driver.
MongoMapper turns objects into a MongoDB representation by calling:
The
to_mongomethod is already defined for a bunch of standard classes, and you can define it for your own classes too. See lib/mongo_mapper/extensions for all the classes that haveto_mongodefined and http://mongomapper.com/documentation/types.html for the documentation on custom types.BUT, if you're content to let your users just hand you a hash, it'll just work.
