我有节点的工作(库存)脚本
var cluster = require('cluster');
var http = require('http');
var numReqs = 0;

console.log("numReqs =", numReqs);
}, 1000);
} else {
// Worker processes have a http server.
http.Server(function(req, res) {
res.writeHead(200);
res.end("hello world\n");
// Send message to master process

模型保持不变.如何同步?请注意,数据结构很重要.
我试图结合这些技术,但没有什么好处,因为实体框架元数据不被breeze.js消耗,即使所有配置设置,这有点棘手的情况,实际上没有这样的例子,所以这是我的示例代码不能正常工作,但不知何故,也许有人会发现我的错误,并最终帮助解决这个难题或将其作为起点.

Run Code Online (Sandbox Code Playgroud) 我有一个产品模型,它有很多领域。其中一些专用于前端应用程序,例如:
var GameSchema = new Schema({
likes: {
type: [{
type: Schema.ObjectId,
ref: 'User'
}]
},
likes_count: {
type: Number
}
});

我不需要likes_count
Db 中的字段,但控制器只返回模型具有的字段,所以我将likes_count
字段添加到 db 模型
exports.some_method = function(req, res){
var game = req.game;
game.likes_count = game.likes.length
res.json(game);
}

有没有办法在发送请求时将额外数据添加到 db 模型中而不将它们放入 db 中?
请注意,问题不在likes_count
现场本身,我有不同的模型,但重点是在 db 模型上有额外的数据。
optional
field和T | undefined
field有什么区别?
export interface Demo {
field1: string | undefined
field2?: string
}

我喜欢的角度只是指令,当我做大嵌套指令时,我使用相同的控制器foreach,所以没有$scope
交互(较少的观察者)
.controller('BaseGridCtrl', function(){
//instead of

var ctrl = this;
//this is for Table-base-directive
ctrl.value = 123;
//this is for Table-head-directive
