Write a function to find all data from Mongo DB and pass to controller
0
I am new in Mean Stack. I install the express in MVC model.
I have a model named Data
let getAllData = ()=>{
Data.find({},(err,data)=>{
if(err) throw err;
var datas = {};
data.forEach((data)=>{
datas[data._id]=data;
});
console.log(datas);
});
}
module.exports = {
Data,
store,
getAllData
}
I want to call getAllData from a controller
var mongoose = require("mongoose");
var passport = require("passport");
var User = require("../models/User");
var DataModel = require("../models/Data");
var userController = {};
// Access to root page
userController.home = function(req, res) {
// res.render('index');
// res.send(Data.find);
DataModel.getAllData();
res.render('index',{//I want to send all the data to this view and view them from the page});
}
All I want is to make a function in the model to access all the data and show them in my view with a controller in middle. I am totally new and I could not exactly find the solution anywhere.
Thank you.

Heads up, of it is a lot of data you'll want to get it in batches.

You should use async await for this. This will allow you to call the function, wait for the promise to resolve and then respond the to request.
const getAllData = async () => {
return Data.find({})
.then(data => {})
.catch(error => {
throw error;
});
};
module.exports = {
Data,
store,
getAllData
};
When you define your function as async it will return a promise, so you can await its response.
var mongoose = require("mongoose");
var passport = require("passport");
var User = require("../models/User");
var DataModel = require("../models/Data");
var userController = {};
// Access to root page
userController.home = async function(req, res) {
// res.render('index');
// res.send(Data.find);
const data = await DataModel.getAllData();
res.render("index", data);
};

Don't mixasync-awaitwithPromisesyntax, use one or the other. ThegetAllDatafunction can simply return thePromisereturned byData.find

It's like mixing.map()andforloops in same function. And for the answer you posted, you just throw the error anyways. Error handling in Express should be delegated to error middleware anyways: expressjs.com/en/guide/error-handling.html
