this is my app.js file for showing and updating info for my posts in one single Ejs template called compose: when I run my code I get this error
**
SyntaxError: missing ) after argument list in C:\Users\john\Desktop\blog\views\compose.ejs while compiling ejs**
app.post("/compose", function (req, res) {
var title= req.body.postTitle
var content= req.body.postText
const post = new Post({
title: title,
content: content
});
post.save(function(err){
if (!err){
res.redirect("/");
}
});
// res.redirect("/");
});
// update posts
app.get('/update/:postid', function (req, res) {
const updateId = req.params.postid;
Post.findById({_id: updateId}, function (err, record) {
if(!err) {
if(window.location.href.indexOf(''))
res.render('compose', {post:record});
}
});
});
and this is my compose Ejs file that I wanna do both showing and updating info with Mongodb in Ejs template:
<h1>Compose</h1>
<form action="/compose" method="post">
<div class="form-group">
<label for="posttitle"> Title</label>
<input type="text" id="" class="form-control" name="postTitle" placeholder="Title" value="<% if(window.location.href.contains("update/") > -1) { %> <%= post.title } %>" >
</div>
<div class="form-group">
<label for="desc">Description</label>
<textarea class="form-control" name="postText" id="desc" cols="30" rows="10" placeholder="Description">
<% if(window.location.href.contains("update/") > -1) { %>
<%= post.content } %>
</textarea>
</div>
<button class="btn btn-myPrimary" type="submit" value="" name="button">Publish</button>
</form>
I tried to show info from mongodb it was okay so then i made a route for updating the info using same template it gives me error

I am fairly new to nodejs and express. I am using nodejs and handlebars to create a simple back end CRUD App. Right now I am stuck on how to pass the value from a form I created in handlebars to an app.get function in my index.js file so inside my app.get function I can use the value to do a database query. After I do the query I want to display the results using app.get and render it to web page.
This is my Handlebars code:
<section id="main" class="wrapper">
<div id="view" class="container">
<section id="main" class="wrapper">
<div id="class" class="container">
<div class="card-body">
<form action="/getid/submit" method="POST">
<div class="form-group">
<label for="id"></label>
<input type="text" class="form-control" id="id" name="id"
placeholder="Enter ID">
</div>
<button type="submit" class="btn btn-primary">Enter ID</button>
</form>
</div>
</div>
</section>
This is the post function in index.js
app.post('/getid/submit',(req,res)=>{
const id = req.body.id;
console.log(id);
res.redirect('page1');
});
This is the app.get function:
app.get('/view/id',(req,res)=>{
//id = ?
var sql = `SELECT * FROM class WHERE Id =${id}`;
db.query(sql,function (err,result){
if(err) throw error;
res.render('page2',{title: 'test', items: rows})
});
});
My main question would be How do I pass the value that I am getting from the app.post form to my app.get function so I can run the query with that ID and render the values to the webpage. THank you in advance.
The id you need to achieve is in request parameters. So you should try:
app.get('/view/:id', (req, res) => {
//id = ?
const id = req.params.id
var sql = `SELECT * FROM class WHERE Id =${id}`;
db.query(sql, function (err, result) {
if (err) throw error;
res.render('page2', { title: 'test', items: rows })
});
});
I am setting up a simple blog site and am having problems making the user authentication setup section. What I want to be happening is to have both the Register form and the Login form on the same page (for style reasons) but my issue is is that, to my knowledge, you cannot have two POST methods on one page. I have tried multiple work arounds, like using PUT or checking if the fields are empty, but these all feel hacky and don't really work. Is there anyway to have two fully functional forms on the same page that both respond to the same route? This is my method for reference:
const express = require('express')
const bcrypt = require('bcrypt');
const passport = require('passport');
const router = express.Router()
const app = express()
const User = require('../models/User')
router.get('/', async (req, res) => {
res.render('pages/account', {
pageQuery: "Account"
});
// const allUsers = await User.find({})
// console.log(allUsers)
// User.remove({}, function(err) {
// console.log('collection removed')
// });
});
router.post('/', async (req, res) => {
let name = req.body.userNameSignUp
let password = req.body.userPasswordSignUp
let passwordConfirm = req.body.userPasswordSignUpConfirm
const hashedPassword = await bcrypt.hash(password, 10);
const newUser = new User({
userName: name,
userPassword: hashedPassword
});
if (!name || !password) {
res.render('pages/account', {
errorMessage: "*Please fill out all the fields",
pageQuery: "Account"
});
} else if (password !== passwordConfirm) {
res.render('pages/account', {
errorMessage: "*Passwords do not match",
pageQuery: "Account"
});
} else {
User.findOne({ userName: name })
.then(user => {
if (user) {
res.render('pages/account', {
errorMessage: "*Username Is Already In Use",
pageQuery: "Account"
});
}
})
}
try {
await newUser.save()
res.redirect('/account')
} catch (e) {
res.render('pages/account', {
errorMessage: "*Welp... The server's down. Come back later",
pageQuery: "Account"
});
}
});
module.exports = router;
and my ejs view for the forms:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Cheese | Account</title>
<%- include('../partials/linkandsrc'); %>
<script src="js/signUpToggle.js" defer></script>
</head>
<body>
<%- include('../partials/header'); %>
<%- include('../partials/navigation'); %>
<section class="signInSec">
<div class="account-container">
<div class="user signInBx">
<div class="imgBx">
<img src="images/SignUp.jpg" alt="">
</div>
<div class="formBx">
<form action="/account" method="POST">
<h2>Sign Up</h2>
<%- include('../partials/errorMessage'); %>
<input type="text" name="userNameSignUp" placeholder="Username">
<input type="text" name="userPasswordSignUp" placeholder="Password">
<input type="text" name="userPasswordSignUpConfirm" placeholder="Confirm Password">
<input type="submit" value="Create Account">
<p class="signin">Already have an account ? Sign In.</p>
</form>
</div>
</div>
<div class="user signUpBx">
<div class="formBx">
<form action="/account" method="POST">
<h2>Sign In</h2>
<%- include('../partials/errorMessage'); %>
<input type="text" name="userNameLogIn" placeholder="Username">
<input type="text" name="userPasswordLogIn" placeholder="Password">
<input type="submit" value="Login">
<p class="signin">Don't have an account ? Sign Up.</p>
</form>
</div>
<div class="imgBx">
<img src="images/SignIn.jpg" alt="">
</div>
</div>
</div>
</section>
</body>
</html>
If you're sure you want to have the same route (/account) handle both the sign-up and the sign-in, then one approach might be to use hidden input fields.
You could place a hidden input in the sign-up form, with name formType (call it whatever you want, this is just an example) and value signup:
<form action="/account" method="POST">
<h2>Sign Up</h2>
<%- include('../partials/errorMessage'); %>
<input type="text" name="userNameSignUp" placeholder="Username">
<input type="text" name="userPasswordSignUp" placeholder="Password">
<input type="text" name="userPasswordSignUpConfirm" placeholder="Confirm Password">
<input type="hidden" name="formType" value="signup">
<input type="submit" value="Create Account">
<p class="signin">Already have an account ? Sign In.</p>
</form>
and similarly in the sign-in form, with name formType and value signin:
<form action="/account" method="POST">
<h2>Sign In</h2>
<%- include('../partials/errorMessage'); %>
<input type="text" name="userNameLogIn" placeholder="Username">
<input type="text" name="userPasswordLogIn" placeholder="Password">
<input type="hidden" name="formType" value="signin">
<input type="submit" value="Login">
<p class="signin">Don't have an account ? Sign Up.</p>
</form>
Then, in your route handler, you could have some logic that differentiates a sign-up from a sign-in using the received formType:
router.post('/', async (req, res) => {
if ('signup' === req.body.formType) {
// Server-sided sign-up logic can go here...
} else if ('signin' === req.body.formType) {
// Server-sided sign-in logic can go here....
} else {
// Something/someone has submitted an invalid form?
}
}
Frontend
I use ejs to create forms
<form action="/users/create" method="POST">
<div class="row">
<div class="col-2">
Id Advance Requisition
</div>
<div class="col-6">
<input type="text" class="form-control" id="IdAdvanceRequisition" name="IdAdvanceRequisition" required/>
</div>
</div>
<div class="row">
<div class="col-2">
NoRef
</div>
<div class="col-6">
<input type="text" class="form-control" id="NoRef" name="NoRef" required/>
</div>
</div>
<div class="row">
<div class="col-2">
NIK
</div>
<div class="col-6">
<input type="text" class="form-control" id="Nik" name="Nik" required/>
</div>
</div>
<input type="hidden" class="id" name="id" />
Back
<button type="submit" class="btn btn-primary btn-sm">Save</button>
</form>
router for the router on the frontend, why can I only use post and get? whereas to delete and update you have to use DELETE and PUT
const express = require('express');
const user = require('../controllers/user')
var cors = require('cors')
const router = express.Router();
router.get('/index', user.getUsers);
router.get('/add', user.getAdd);
router.post('/create',cors (), user.createUsers);
router.get('/detail/:id', user.readUsers);
router.post('/delete/:id', cors (), user.deleteUsers);
router.get('/edit/:id', user.detailUpdate);
router.post('/update/:id',cors (), user.updateUsers);
module.exports = router;
controllers for add
createUsers : async (req,res) => {
try {
const Backend = await getBackend();
const dataBackend = await Backend.json();
const user = {id: uuidv4(), IdAdvanceRequisition: req.body.IdAdvanceRequisition, NoRef: req.body.NoRef, Nik: req.body.Nik};
dataBackend.push({...user, id: uuidv4()});
fetch('http://localhost:8000/users', {
method: 'post',
body: JSON.stringify(user)
})
console.log(`Data with the id: ${user.id} added to the database!`);
res.redirect('/users/index');
} catch (error) {
res.send(`data error`);
}
}
Results
[{"id":"3cc4ed6e-5974-4661-ade7-ec448ac0e7e3"}]
Problem: I tried to send all data to the backend, but only the UUID was sent. How can I solve this problem
I´m doing a CRUD app in Sails, but the delete method doesn´t works fine.
The Homepage.ejs view is a simple form:
<form action="/todo" method="post">
<input type="text" name="title">
<br><br>
<input type="text" name="description">
<br><br>
<button type="submit">Create</button>
</form>
<hr>
<ul>
<% _.each(todos, function(todo){ %>
<li style="<% if(!todo.done){ %>color: red;<% } %>"><b><%= todo.title %></b> - <%= todo.description %> </li>Detail
<form action="/todo/<%= todo.id %>" method="post">
<input type="hidden" name="_method" value="put">
<button type="submit">Completed</button>
</form>
<form action="/todo/<%= todo.id %>" method="post">
<input type="hidden" name="_method" value="delete">
<button type="submit">Delete</button>
</form>
<% }) %>
</ul>
`
The ToDoController of DELETE and findOne methods:
delete:function(req, res){
ToDo.destroy(req.param('id')).exec(function(err, todo){
if(err) return res.serverError();
return res.redirect('/');
});
},
findOne: function(req, res){
ToDo.find(req.param('id')).exec(function(err, todos){
if(err) return res.serverError();
return res.view('details', { id: req.param('id'), title: req.param('title'), description:req.param('description')});
});
}
The routes:
'/': 'ToDoController.index',
'POST /todo' : 'ToDoController.create',
'PUT /todo/:id': 'ToDoController.update',
'DELETE /todo/:id' : 'ToDoController.delete',
'GET /detail/:id': 'ToDoController.findOne'
And the details.ejs view:
<h1> ID task: <%= id %> </h1>
<h3>Title: <%= title %></h3>
<p> Task: <%= description %></p>
Any idea??
Try using your console to debug your application
delete:function(req, res){
console.log(req.param('id'));
ToDo.destroy(req.param('id')).exec(function(err, todo){
console.log(todo);
if(err) return res.serverError();
return res.redirect('/');
});
}
If you still have trouble, you should report what your console is outputting.
i am setting a form with Mean Stack,
in form.html i have
<div ng-controller="InfoCtrl">
<form method="post" ng-submit="info()" name="infoForm">
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="Homme" value="Homme" checked>
Homme
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="Femme" value="Femme">
Femme
and in the controller info.js i have :
angular.module('MyApp')
.controller('InfoCtrl',[ '$scope', 'infor', function($scope, infor) {
$scope.info = function() {
infor.info({
age: $scope.age,
sexe: $scope.optionsRadios
});
};
}]);
another file infor.js, it only contains the error message after the set of the form, in the class server.js i have this function:
app.post('/infor/info', function(req, res, next) {
console.log('ok');
var query = {'email' : 'mail#mail.fr' };
var age1 = req.body.age;
console.log(req.body.optionsRadios);
User.findOneAndUpdate(query,{ age: age1 } , {upsert:true},function(err, doc){
if (err) return res.send(500, { error: err });
return res.send("succesfully saved");
});
});
but i didn't knew how to save the answer of the button radio in the query like i did in the set of new text. I have searched in many forms but it i didn't found an answer!
