NodeJS pass Array from MongoDB to EJS file

i'm trying to make an option tag for every item which is in my Array in MongoDB. I have tried some ways but EJS throws me everytime the same error "gate is not defined"..
Here is my function in my route:
router.post('/neueBuchung_spediteur', (req, res) => {
User.findOne({username: req.user}, function (err, user) {
res.render('neueBuchung_spediteur', {
gate: user.gate
});
});
And this is my EJS function:
<select id="torauswahl" name="torauswahl" style="padding:10px;font-size: large; width: 300px">
<% for (var i = 0; i < gate.length; i++){%>
<option value="<%=gate[i]%>"><%=gate[i]%></option>
<%}%>
</select>
thats my full JS file for understanding the logic:
const express = require('express');
const router = express.Router();
// Load Buchung model
const Buchung = require('../DB/models/Buchung');
const User = require('../DB/models/User');
const Tor = require(('../DB/models/Tor'));
const { ensureAuthenticated } = require('../DB/config/auth');
const passport = require('passport');
//Startseite Breuninger
router.get ('/startseite_breuninger', ensureAuthenticated, (req, res) => {
Buchung.find(function (err, buchungen) {
if (err)
return res.send(err);
res.render('startseite_breuninger',{
vorname: req.user.vorname,
buchungen: buchungen || []
});
});
});
//startseite Spedi
router.get ('/startseite_spediteur', ensureAuthenticated, (req, res) => {
Buchung.find(function (err, buchungen) {
if (err)
return res.send(err);
res.render('startseite_spediteur',{
buchungen: buchungen || []
});
});
});
//Buhchungsübersicht mitarbeiter
router.get('/buchungsuebersicht', (req, res) => res.render('buchungsuebersicht'));
//Buhchungsübersicht spedi
router.get('/neueBuchung_spediteur', (req, res) => res.render('neueBuchung_spediteur'));
//torauswahl spedi
router.get ('/torauswahl', (req, res) => {
Buchung.find(function (err, buchungen) {
if (err)
return res.send(err);
res.render('torauswahl',{
buchungen: buchungen || []
});
});
});
//torverwaltung mitarbeiter
router.get ('/torverwaltung', (req, res) =>{
Tor.find(function (err, tor) {
if (err)
return res.send(err);
res.render('torverwaltung',{
tor: tor || [],
});
});
});
//Update Benutzerdaten Breuni
router.post('/update_detailansicht_breuninger',(req,res) =>{
const username = req.body.username;
const telefon = req.body.telefon;
const email = req.body.email;
User.update({username: username}, telefon);
res.render('detailansicht_breuninger');
});
//insert
//insert
router.post('/neueBuchung_spediteur',ensureAuthenticated,(req, res) => {
const {sendungsstruktur, datepicker, timepicker1, timepicker2, sendungen, EUP, EWP, pakete, bemerkung, teile } = req.body;
var user = req.user;
if (errors.length > 0) {
User.findOne({ username: req.user}, function (err, user) {
console.log(JSON.stringify(req.user));
if (err) { throw err; }
if (user) {
res.render('neueBuchung_spediteur', {
gate: user.gate || []
});
}
});
}
const newBuchung = new Buchung({
sendungsstruktur,
datepicker,
timepicker1,
timepicker2,
sendungen,
EUP,
EWP,
pakete,
bemerkung,
teile
});
newBuchung.save()
.then(buchung =>{
res.send('saved')
})
.catch(err=>console.log(err));
console.log(newBuchung)
});
router.post(
'/login',
passport.authenticate('local', {
failureRedirect: '/login'
}), (req, res) => {
if (req.user.admin == "spediteur") {
res.redirect('/buchungen/startseite_spediteur');
} else {
res.redirect('/buchungen/startseite_breuninger');
}
});
module.exports = router;
Im thankful for any help :)

I think the issue is that req.user is undefined. Can you try logging req.user during your route function?
router.post('/neueBuchung_spediteur', (req, res) => {
User.findOne({username: req.user}, function (err, user) {
console.log(JSON.stringify(req.user))
res.render('neueBuchung_spediteur', {
gate: user.gate
});
});

But i don't how to call them from angular.js
I have my intro.html as below

I would like to call them when user click each link. If some one could help me developing angularjs services.

Best would be to create a service but you can do it in the ctrl aswell
// users.service.js
var userService = angular.module('app.userService', ['ngResource'])
.factory('users', function ($http, $q) {
var that = this;
this.data = {};
var url = '';
var factory = {
get: get
};
function get() {
url = '/api/users';
var defer = $q.defer();
$http.get(url).
success(function (data, status, headers, config) {
defer.resolve(data);
}).
error(function (data, status, headers, config) {
defer.reject(data);
});
return defer.promise;
};
});
// some.controller.js
angular.module('app.somectrl', ['app.userService'])
.controller(someController);
function someController(userService) {
userService.get().then(function (res) {
// do sth
}, function (err) {
// handle error
});
}

express js cannot GET /page

I am very stuck with a routing error on express.js. I am using jade to render my page views. I have read all the docs and refactored many times to no avail.
This is the plain contents of the link that is pointing to the '/sell' route.
index.jade
include layout
html
button.btn.btn-primary(type='submit', href='/sell') Add Item
When clicking this button the browser returns the following as a 404:
Cannot GET /sell
The problem here is that all other routes work correctly, if you are to modify the above href to other pages i.e. '/' , '/sign_in', etc no error occurs. The problem appears to be isolated to the '/sell' route.
The controller with the '/sell' route is below:

button#btnSubmit.btn.btn-primary(type='submit') Post Item

I think it's acting as form post and tries to reach app.post('/sell')
Change it:
button.btn.btn-primary(type='submit', href='/sell') Add Item
to:
a.btn.btn-primary(href='/sell') Add Item
also remove some parts of middleware and keep only these lines:
app.set('views', 'app/views');
app.set('view engine', 'jade');
app.set('port', process.env.PORT || 3000);
app.use(logger('dev'));
and then navigate in Your browser to /sell route, check if it's working.
if Yes - so problem with one of middlewares that we have deleted to check.

You should add a logger middleware and see what error the server gives when you try to go to that route. Another thing to try would be to rename the sell route and see if that works. That could indicate a conflict with another one of your routes, although it's not clear where this would be from looking at your code.

ExpressJs - Finding records matching route parameter

I have been building out a tagging system for my ExpressJS application and I have been able to create my routing to pick up on the individual tags that are used for my record, but the issue I am running into is trying to display content associated with the selected tag. For instance a record has a tag "Mouse", when clicked the route correctly goes to /tag/mouse, but I'm not sure if I should use a loop within my template to display only those values or if I should really be using a method within my route. I'm currently using nothing and the value being displayed on the tag page is undefined. I have a feeling the route method is what I am looking for.
Here is the main focus of my routes file:
var express = require('express');
var router = express.Router();

blogpost.featureImage = req.body.featureImage; // set the blog image
blogpost.blogUrl = blogpost.title.toLowerCase().replace(/\s+/g,"-");
blogpost.author = req.body.author; // set the author name
blogpost.tagline = req.body.tagline; // set the tagline
blogpost.content = req.body.content; // set the blog content
blogpost.category = req.body.category; // set the category
blogpost.tags = req.body.tags.trim().split(","); // set the tags
//Save Blog Post

ExpressJS PUT method undefined objecty issue

I am trying to use the PUT method to update a record in my database, but I am running into a issue where the object is not defined.
ReferenceError: blogpost is not defined
I am referencing this tutorial with my routing steps and noticed that despite the variable being defined in my /blogs route, meaning that it is local to that function, that in the tutorial, they don't define the variable again when routing their put method. They simply call the object's property that they plan to update. Is there a reason why I'm not able to access this object? Is it a scope issue?
routes.js:
var express = require('express');
var router = express.Router();
var blogDB = require('../config/blogDB.js');
var Blogpost = require('./models/blogModel.js');
//index
router.route('/')
.get(function(req, res) {
var drinks = [
{ name: 'Bloody Mary', drunkness: 3 },
{ name: 'Martini', drunkness: 5 },
{ name: 'Scotch', drunkness: 10}
];
var tagline = "Lets do this.";
res.render('pages/index', {
drinks: drinks,
tagline: tagline
});
});
//blog
router.route('/blog')
// START POST method
.post(function(req, res) {
var blogpost = new Blogpost(); // create a new instance of a Blogpost model
blogpost.title = req.body.title; // set the blog title
blogpost.content = req.body.content; // set the blog content
//Save Blog Post
blogpost.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Blog created.' });
});
}) // END POST method
// START GET method
.get(function(req, res) {
Blogpost.find(function(err, blogs) {
if (err)
res.send(err);
res.json(blogs);
});
}); // END GET method
//Route for individual blogs
router.route('/blog/:blogpost_id')
// START GET method blog by ID
.get(function(req, res) {
Blogpost.findById(req.params.blogpost_id, function(err, blog) {
if (err)
res.send(err);
res.json(blog);
});
}) // END GET method blog by ID
// START PUT method
.put(function(req, res) {
Blogpost.findById(req.params.blogpost_id, function(err, blog) {
if (err)
res.send(err);
blogpost.title = req.body.title; // update the blog title
blogpost.content = req.body.content; // update the blog content
blogpost.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Blog updated.' });
});
});
});
//about
router.get('/about', function(req, res) {
res.render('pages/about');
});
module.exports = router;
Specific area where the issue is created:
// START PUT method
.put(function(req, res) {
Blogpost.findById(req.params.blogpost_id, function(err, blog) {
if (err)
res.send(err);
blogpost.title = req.body.title; // update the blog title
blogpost.content = req.body.content; // update the blog content
blogpost.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Blog updated.' });
});
});
});

Blogpost.findById(req.params.blogpost_id, function(err, blog) {
Should be:
Blogpost.findById(req.params.blogpost_id, function(err, blogpost) {
