根据日期（月）使用node.js和mongodb过滤并重新排列结果 [英] Filter and re-arrange results using node.js and mongodb according to date(month)

问题描述

我使用Node.JS和Express创建了一个服务器。数据库是MongoDB，ORM是Mongoose。这是我必须做的。

I created a server using Node.JS and Express. Database is MongoDB and ORM is Mongoose. Here's what I have to do.

    {
        "_id": "5788fcf7bfecf0c135178418",
        "incomeDate": "2012-01-01T00:00:00.000Z",
        "name": "Sales",
        "type": "Sales one",
        "amount": 5500,
        "__v": 0
    }

这是我从数据库中获取的对象。我想按日期（实际按月）过滤这些对象。我将使用Angular Charts在图表中显示月收入。 （ https://jtblin.github.io/angular-chart.js/ ） - >角度条形图。

This is the object I'm getting from database. I want to filter these objects by date ( actually by month). I'm going to display monthly income in a chart using Angular Charts. (https://jtblin.github.io/angular-chart.js/) -> Angular Bar chart.

因此，如果特定月份没有金额，则列表中应为零（0）。列表必须是这样的。列表中有12个元素。这只是一个例子。

So if there's no amount in a specific month, there shoud be zero (0) in the list. The list must be like this. there are 12 elements of the list. This is just an example.

[200,1200,10,0,124,542,1254,500,0,1254,36,87]

[200,1200,10,0,124,542,1254,500,0,1254,36,87]

我怎么能在node.js和mongoose中这样做？必须使用incomedate进行过滤并在node.js中执行一些代码.....

How can I do this in node.js and mongoose ? Have to filter using incomedate and do some code in node.js.....

推荐答案

将其称为：

var date = new incomeDate();

{$group: {date: date.getMonth()}
