请注意,我是新编码员。
我不知道如何在Mongo中高效地讲述数据,因此我可以重用它并随时间进行比较。
我正在构建一个管理仪表板,在该仪表板上我从HTML收集数据并将其存储在Mongo Collections和定义的模式中。数据将转换为图形供用户查看。
现在,我正在收集今年的数据。 明年,我将收集完全相同或几乎完全相同的数据。
然后我要创建比较。
最初,我想到创建多个模型来进行区分。
所以从下面的代码中可以找到
:今年的模型将是2019manageSchema .... 明年的模型将是2020manageSchema ... 但这些架构与我收集相同数据的方式完全相同。
但是我认为这不是最佳实践。
此外,我在考虑路线,要求所有mdoel并使其通过每条路线会很混乱。

var mongoose = require("mongoose"),
math = require('mathjs');
*****DATABASE CONFIG*******
var manageSchema = new mongoose.Schema({

module.exports = mongoose.model("Manage", manageSchema);
轮次:
var express = require("express");
var router = express.Router();
var User = require("../models/user");
var Manage = require ("../models/manages");
//Manage
//Index Route for manage - view graphs + edit
router.get("/manage", isLoggedIn, function(req, res){
Manage.find({}, function(err, manages){
if(err){
console.log("ERROR");
} else {
res.render("manage", {manages: manages});
}
});
});
//NEW ROUTE - sends to forms page for Manage
router.get("/manage/new_admin0", isLoggedIn, function(req, res){
res.render("manageForm");
});
//CREATE ROUTE - POST request to manage
router.post("/manage", isLoggedIn, function (req, res){
//create demog
Manage.create(req.body.manage, function(err, newManage){
if(err){
console.log(err);
} else {
//add username and id to recruit
newManage.user.id = req.user._id;
newManage.user.username = req.user.username;
//save recruit
newManage.save();
//redirect
console.log(newManage);
res.redirect("/manage");
}
});
});
//SHOW ROUTE - Specific info
router.get ("/manage/:id", checkOwnership, function(req, res){
Manage.findById(req.params.id, function(err, foundManage){
if(err){
res.redirect("back");
} else {
res.render("showmanage", {manages: foundManage});
}
});
});
// EDIT ROUTE - form to update existing data
router.get("/manage/:id/edit", checkOwnership, function(req, res){
Manage.findById(req.params.id, function(err, foundManage){
res.render("editmanage", {manages: foundManage});
});
});
//UPDATE ROUTE - use edit form info and update existing data
router.put("/manage/:id", checkOwnership, function(req, res){
Manage.findByIdAndUpdate(req.params.id, req.body.manage, function(err, updateManage){

res.redirect("back");
} else {
res.redirect("/manage/" + req.params.id);
}
});
});
//middleware

}
function checkOwnership(req, res, next) {

请在不影响当前路线的情况下帮助您进行存储,最好是如何存储。
答案 0 :(得分:0)
您可以使用$year
,$month
,$week
之类的MongoDB聚合管道运算符根据日期对数据进行分组
{
$project: {
month: { $month: "$created" },
year: { $year: "$created" },
}
},
{
$group: {
_id: {
year: '$year',
month: '$month'
},
count: {
$sum: 1
}
}
}
