here is route.js code for login
var path = require('path');
module.exports = function(app) {
app.get('/', function(req, res) {
res.render('login');
});
app.post('/login', function(req, res) {
//from here i should go to login model
});
};
here is my login.ejs
<form action="/login" method="post">
<input type="text" name="username" placeholder="username">
<input type="password" name="password" placeholder="password">
<input type="submit" name="" value="Submit">
</form>
now my question is that how i can use login model from route.js (url is like "login") i know i can use this type as describe below in route.js but i want that first it go to router and from then i go to login model more description eg it go through "/login" route from there it go to login model where i want to add insert login after that if it response success then it go to "/home" else it go to "/"
"var User = app.models.user;"
i what something like this in user.js (model)
module.exports = function(User) {
//here i want to accept login form method and insert it into dataabase
};
or this is not possible or it is incorrect way i don't know much so please help

First go to the loopBack documentation and read it carefully how to create models and its control flow , surely you will get clear picture

I'm trying to make it so that when a user has admin he should have access to the router. But unfortunately, it does not work, I'm getting an error that isAdmin is not defined, but I have it in the database.
function isAdminLogged(req, res, next) {
if (req.User.isAdmin==="true") return next();
res.redirect('/admin');
}
//ROUTES
app.get('/admin', isAdminLogged, (req, res) => {
res.render("admin", { title: "Admin Area" });
})
Also, I would love to make it when a user is an admin he can see a div in an index.hbs
<div class="home">
<h1>Home</h1>
Logout
</div>
{{#if user.isAdmin}}
<div>
<h1>Hello Guys</h1>
</div>
{{/if}}
I'm new to express and I'm trying my best to understand, thank you in advance!
I have built authentication, and using mongodb but EJS template instead of Handlebars. I think if you go through it then that will help you a lot.
Here is the link to my repo CAMP.
The information that you have provided may be not sufficient to solve your issue from my side.
I'd like to be able to create a custom path. for example, if a user clicks a button [create room], the browser redirects the user to: http://www.example.com/[room_id]/index.html
Is there anyway to implement this? The user would be submitting a form, with a button. something along those lines.
basically here is what i have
index.html
<form method='POST' name='path_id' id='clickedButtom'>
<input id="pickName" class="center-align" type='text'>
<input id='rea2dy' value=" Ready >" type='submit'>
</form>
server.js
app.get('path_id', function(req, res) {
res.send('hello');
});
//I was the path_id to be a random string of letters and numbers basically
For all the URLs you're talking about, you can define a single Express route in advance like this that will have code inside the route to look at the room id and act accordingly:
app.post('/createRoom, (req, res) => {
// do whatever you do here to create the room data structure on the server
// and assign it an ID
let roomID = ...;
res.redirect(`/${roomID}/index.html`);
});
app.get('/:roomID/index.html', (req, res) => {
let roomID = req.params.roomID;
// now render whatever you want the user to see for this particular room
res.send(...);
});
I am trying to create a simple form handler using express. Here is a similar question but I can't related it with my problem. I have written all of my file Here anyone can check it by using all of my file. For better understanding I copy my code here:
app.js code:
const express = require('express');
const app = express();
//routes
app.get('/',function(req,res){
res.send('This is root dir');
});
app.get('/friends',function(req,res){
var friends=['sakib','emon','rayhan'];
res.render('friends.ejs',{friends:friends});
});
app.get('/addfriend',function(req,res){
res.send('ADD friend page launch!!!!!');
});
app.listen(3000,function(){
console.log("server has started on port 3000!!!");
});
ejs(friends.ejs) code:
<h1>Here is list of your Friend:</h1>
<%friends.forEach(function(friend){%>
<li><%=friend%></li>
<%});%>
<form action="/addfriend" method="POST">
<input type="text" name="friend" placeholder="name">
<button>
Submit
</button>
</form>
When I type any name in the input box and clicked Submit it didn't post to /addfriend. I didn't understand where is my problem. Please goto input box(link) after started the server.
For better understand what's my actual problem is then please use goorm IDE(shared file) where I uploaded everything.
You are using get request instead of post for addfriend.
app.post('/addfriend',function(req,res){
console.log("I'm called wohoo!");
res.send('ADD friend page launch!!!!!');
});
I'm trying to upload a file in meteor using HTTP POST method and enctype="multipart/form-data"
WebApp.connectHandlers.use("/api/v1/upload", function(req, res, next) {
console.log(req.files); //undefined
console.log(req.file); //undefined
console.log(req);
})
I tried with WebApp but getting undefined file property under request object
I also tried with multer and Picker but no luck.
const _multerInstanceConfig = { dest: '/tmp' }; // Temp dir for multer
const _multerInstance = multer(_multerInstanceConfig);
Picker.middleware(_multerInstance.single('photo'));
Picker.route('/api/v1/upload', function(params, req, res, next) {
console.log(req.files); //undefined
console.log(req.file); //undefined
console.log(req);
})
This is simplest form I'm trying to upload is
<form action="http://localhost:3000/api/v1/upload" method="POST" enctype="multipart/form-data">
<input type="file" name="file" />
<input type="submit" value="Upload File" />
</form>
Am I missing something here? not sure.
Also, I don't want to upload files using base64 data string via DDP as it very slow.
I've check couple of link also with no luck
multer - req.file always undefined
https://github.com/noris666/Meteor-Files-POST-Example
PS: I need to upload images via native Android/iOS clients.
Thanks, everyone, who has spent their time on my question, I got the solution for the problem from git issue, I raised.
I'm posting here my solution if someone else also faces the similar problem.
It was because of the name of this input field
<input type="file" name="file" />
which doesn't match with
Picker.middleware(_multerInstance.single('photo'));
changing either of them to will make it work perfectly.
Hi for whatever reason i cannot use packages e.g. multer to upload file to node server. So i found example online, if just upload file in the form, it works fine.
Now i want to send another field "password" together with the file during submit, just cannot make it a work.
I do know there're plenty modules out there, for now just want to this example to work.
<form style="height: 100%;padding-bottom:63px;">
<p>
<input type="file" class="FirmwareFile"
name="myUpload" file-model="upload.newFwFile">
</p>
<p>
<input type="password" name="password" id="password"
placeholder="Password"
ng-model="upload.controllerPassword"
class="formInput">
</p>
</form>
httpSvc.uploadToUrl(myFile, myPd, myServerIPAddress, myRoute) {...}
factory.uploadToUrl = function (fwFile, pd, myServerIp, myRoute) {
var fd = new FormData();
//fd.append('passwd', pd); // cannot pass password to server side ?
fd.append('file', fwFile); // only this works
var deferred = $q.defer();
var completeUrl = ......
$http.post(completeUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
}).success(function (data) {
deferred.resolve(data);
}).error(function () {
deferred.reject();
});
return deferred.promise;
}
in server side, where to extract the password info please ?
var UploadImage = function(req, res, callback){
var destFile = fs.createWriteStream(uploadDest + "mytest");
var fileSize = req.headers['content-length'];
req.pipe(destFile); //why not sth. like req.body.file.pipe() ?
...
};
Your form does not have
<form enctype="multipart/form-data" action="..." method="...">
...
</form>
You will be better off using node-formidable. The example works straight out of the box. You might also want to look into angularJS specific form upload directives that have been made. No sense in reinventing the wheel.
Cheers
