Sails.js简单的私人消息（pub / sub和models）

My Goal:

我的目标：

Create a private messaging platform using Sails.js with the simplest code possible

使用Sails.js创建一个私有消息传递平台，尽可能使用最简单的代码

Assumptions of Best Practices:

最佳实践假设：

Use Sails.js Webockets for realtime notifications
使用Sails.js Webockets进行实时通知
Use Sails.js PubSub for DB use with websockets
使用Sails.js PubSub将数据库与websockets一起使用
Use Sails.js .watch() to get messages
使用Sails.js .watch（）来获取消息

My Questions:

我的问题：

Can I have a socket watch only certain new models (e.g. find where userid matches sender or recipient id) OR do I need to set up rooms? Selective watching seems much easier, but the documentation doesn't seem to support it.
我可以只使用套接字监视某些新模型（例如查找userid与发件人或收件人ID匹配的位置）还是我需要设置房间？选择性观看似乎更容易，但文档似乎不支持它。
If any of my above assumptions or questions are not the best way to realize my goal, then what is the simplest way to implement private messaging using Sails?
如果我上面的任何假设或问题不是实现我的目标的最佳方式，那么使用Sails实现私人消息传递的最简单方法是什么？

What I've Tried:

我试过的：

Subscribing and watching a socket
订阅和观看套接字
Reading the Sails.js documentation
阅读Sails.js文档
Looking at the sailsChat example (uses rooms)
看着sailsChat例子（使用房间）
Searching * and Google for sails chat examples
搜索*和Google搜索sails聊天示例

The simplest way I guess it is using the socket.io implemented in sails, if I remember correctly it is simply called socket.

最简单的方法我猜它是使用在sails中实现的socket.io，如果我没记错的话，它简称为socket。

All controllers can be called with socket.io (client side) IIRC. The approach that I took is to create a model called messages, and then simply create few endpoints for the messages. If you want to use the models (pub/sub) it is possible to subscribe just to the ones you want. you can subscribe every single user to just a single Model, even if you have plenty of them.

可以使用socket.io（客户端）IIRC调用所有控制器。我采用的方法是创建一个名为messages的模型，然后简单地为消息创建几个端点。如果您想使用模型（pub / sub），可以只订阅您想要的模型。您可以将每个用户订阅到一个模型，即使您有足够的用户。

What I used to do is do it manually, when I receive one message, i would emit it to the right client straight away. But if you want to write less code probably you simply have to subscribe the users to your model Model.subscribe()( http://sailsjs.org/documentation/reference/web-sockets/resourceful-pub-sub/subscribe ) so when a message is added to the Database then you can send it to whoever you need to.

我以前做的是手动完成，当我收到一条消息时，我会立即将它发送给正确的客户端。但是如果你想编写更少的代码，你可能只需要将用户订阅到模型Model.subscribe（）（http://sailsjs.org/documentation/reference/web-sockets/resourceful-pub-sub/subscribe），这样当消息添加到数据库时，您可以将其发送给您需要的任何人。
