Cannot delete mongodb entry with node and handlebars - node.js

I tried various ways to delete a entry but no luck. I know I'm close. I did use "post" instead of "delete" with no luck. I did the action request on the html, no luck. Im in a pickle :(
My routers:
router.delete('/:id',function(req, res){
Docket.findById(req.params.id, function(err, docket){
docket.remove(function(err){
res.redirect('/dockets');
});
});
});
Handlebars:
<form name="create-docket-form" id="create-docket-form" method="post">
<div class="form-submit">
<input type="submit" name="delete" value="Delete my docket" />
</div>
</form>

In your form, you are using method method="post", but your route is listening for DELETE requests: router.delete('/:id',function(req, res){ So this router is never triggered because the app can't found the route.
I wonder, how do you send your requests, but in if you are using no JavaScript code, you can work around this by applying approach from this answer.

I did solve this problem, first, you have to change the "delete" to "get" in the "router.get()", after that, you go to HandleBars file and put a tag 'button' inside the tag '', put the 'href: '/adress/{{variable to delete}}', go to your node.js and prepare the route, now I'll show you my code:
NODE.EXPRESS / .JS:
app.get(`/del-comander/:comand`,express.json() ,(req,res)=>{
let comanderDel = req.params.comand
Comander.deleteOne({comander: comanderDel}).then(()=>{
console.log(`deleted: ${comanderDel}`)
res.redirect('back')
}).catch((err)=>{
res.send(err)
})
}),
HANDLEBARS:
{{#each comanders}}
<strong> comander: </strong>{{comander}} <br>
<strong> skill: </strong>{{skill}} <br>
<strong>season: </strong>{{season}} <br>
<a href='/del-comander/{{comander}}'><button>delete</button></a>
<br>
<hr>
{{/each}}
OBS: the args inside '{{}}' was connected with the DataBase, I also did more than just delete the data and printed it to the screen, so each data could be deleted separately, I do not know if my answer was good, but somebody else could have this same problem if you want more code just ask.

Reset Password Page Not Rendering Correctly When Accessing from Reset Email Link

Ok, so first off, this is my first post. I've searched high and low for a solution, but have found none. I have posted this first on Udemy, for the course I've taken, but no one has answered, so I'm reposting it here.
I have been trying very hard to figure out why the new-password page will not display correctly for me. The reset link works fine, and I can even reset the password on my new password page when I am sent there from the email link.
However, no matter what I do, I can't get it to display any styling. It only gives me basic html. The logic works fine, it's just the page that doesn't display correctly.
I know it isn't a path issue to the css folder either. If I simply render as another basic page without any token logic, such as replacing my index page with the new-password page, then it displays normally. I just don't know what I'm missing, or if there was some updates that I need to take into consideration.
I'm hoping someone sees this and can help me out. It's the only thing that doesn't work right, and it's very frustrating.
Just to be a little more clear, if I do something like below, and just replace or create a route, the page shows up correctly. It's the token logic I believe that is breaking the rendering, I just don't know how, since I don't get any errors.
Please let me know what code you may need to see, as I'm not sure what sections would be helpful, there are a lot of moving parts here. I will be happy to post whatever is needed.
exports.getNewPassword = (req, res, next) => {
res.render("auth/new-password", {
path: "/new-password",
pageTitle: "Update Password",
});
};
With the logic built-in and following the email reset link, the below will not render any styling, only the html.
exports.getNewPassword = (req, res) => {
const token = req.params.token;
User.findOne({
resetToken: token,
resetTokenExpiration: { $gt: Date.now() },
})
.then((user) => {
if (!user) {
req.flash(
"error",
"That reset password link has already been used."
);
return res.redirect("/");
}
let message = req.flash("error");
message.length > 0 ? (message = message[0]) : (message = null);
res.render("auth/new-password", {
path: "/new-password",
pageTitle: "New Password",
errorMessage: message,
userId: user._id.toString(),
passwordToken: token,
});
})
.catch((err) => console.log(err));
};
I am using ejs for templating as well. As I said above, if I remove all token logic and just render the page as a normal view, it works fine.
<main>
<% if (errorMessage) { %>
<div class="user-message user-message--error"><%= errorMessage %></div>
<% } %>
<form class="login-form" action="/new-password" method="POST">
<div class="form-control">
<label for="password">Password</label>
<input type="password" name="password" id="password">
</div>
<input type="hidden" name="userId" value="<%= userId %>">
<input type="hidden" name="passwordToken" value="<%= passwordToken %>">
<input type="hidden" name="_csrf" value="<%= csrfToken %>">
<button class="btn" type="submit">Update Password</button>
</form>
</main>
Well, in case anyone stumbles across this, the answer was pretty simple, though I'm not sure why in this one instance is was a problem. However, the solution was to add a forward slash in front of my path to the css location for the update password page.
Again, not sure why it needed it, seeing as all my other css and view pages were in the same folder structures and worked fine, but it apparently solved the issue. SMDH.
<link rel="stylesheet" href="/css/login.css" />

use href tag for different html pages but with same url id in express

i'm trying to switch between home and profile page for same user with click on each button. also except change between home and profile,id should stay the same.
but after click on profile button only id will be changed and it uses profile as id
(i used ejs as format for my views/html pages)
any idea how can i fix it?is that even possible?
there is my nav code:
<nav>
<div class="nav-wrapper teal darken-4">
BAZAART
<ul class="right hide-on-med-and-down">
<li><a class="waves-effect waves-light btn teal lighten-1" href="home"> <i class="material-icons right">home</i> home</a></li>
<li><a class="waves-effect waves-light btn teal lighten-1" href="profile">profile <i class="material-icons right">account_box</i></a></li>
</ul>
</div>
</nav>
homeController:
exports.sendReqParam = (req, res) => {
let userHome = req.params.userHome;
res.render("home", { name: userHome });
// res.send(`This is the homepage for ${userHome}`);
};
exports.respondWithName = (req, res) => {
let paramsName = req.params.myName;
res.render("profile", { name: paramsName });
}
main.js
app.get("/profile/:myName", homeController.respondWithName);
app.get("/", homeController.respondInfo);
app.get("/home/:userHome", homeController.sendReqParam)
I was recently making a blog website, where I write a post and it displays it on the home page. But if we wanted to go to the specific post page, instead of making another separate page for each new post, we made a post.ejs page instead, and later to acces the specific post we simply used something called lodash. I'll show you an example of it, so it makes more sense, and I'll show you the code we used.
So the example is this, I go to the compose.ejs page and I write a random post: title=Post, content=A random lorem ipsum
and lets say we write another post: title=Another post, content=Another random lorem ipsum
Okay so now everytime we write a blog post it sends us to the home page (where we currently are) and it shows the two blogs posts. If we wanted to go to the specific url of the post, we simply write this link localhost:3000/posts/Another post hit enter and it takes us to the second post we wrote.
And this is the code we used inside the app.js:
app.get("/posts/:postName", function(req, res){
const requestedTitle = _.lowerCase(req.params.postName);
posts.forEach(function(post) {
const storedTitle = _.lowerCase(post.title);
if (storedTitle === requestedTitle) {
res.render("post", {title: post.title, content: post.content});
}
});
});
In the app.js code, we see in the app.get /posts/:postName and this is just the name that is going to show in the url, :postName is like a variable and it will store whatever the user writes.
In the second line, we use lodash to rewrite what the user wrote to what we want, for example if the user wrote AnoTheR POst it will automatically change it to another-post, and we store it in a constant called requestedTitle.
Next is a forEach loop on a posts array (where we store every post), and this is just to go throught every post and check the names.
In the 4th line, we are again using lodash for the same thing, but this time arround for the title of each individual post, and storing it in a constant called storedTitle.
And last, an if statement, where if both the names are the same then it will render the post.ejs page, and we just pass down the title and content from the selected post using this code , {title: post.title, content: post.content}.
And this is the code we used inside the post.ejs:
<%- include("partials/header") -%>
<br>
<div class="card">
<h2 class="card-header"> <%= title %> </h2>
<div class="card-body">
<p class="card-text"> <%= content %> </p>
</div>
</div>
<%- include("partials/footer") -%>
As you can see this post.ejs isn't hard to explain, the top and bottom lines where it says include("partials are just the header and footer templates I use, just to save time coding. Whats inside is what the post.ejs will render when it gets called.
I hope it wasn't that confusing, I'm still learning to code and I hope it helps you with what you are looking for. I think this isn't the exact answer for your question, but I think it will help you navigate your way throught.
If you need more explanation or help, this is my instagram: #cemruniversal, I'm always happy to help if I can.
Edit: 30 minutes after original post
I think I found a way it could work, I'll show you a piece of code from the same blog website.
Whenever I want to compose a new post I use this code:
app.get("/compose", function(req, res){
res.render("compose");
});
And obviously there is a form for you to write the post, and after you submit, it sends you to the home page, and saves the post. For that I used this piece of code:
app.post("/compose", function(req, res){
const post = {
title: req.body.postTitle,
content: req.body.postBody
};
posts.push(post);
res.redirect("/");
});
I had an idea for your website, what if when you pressed the Profile button, it renders a specific page on your site, and when you press another button it renders another page. It could work, wouldn't it?
Please try it out and tell me how it went.
I think something like this:
<nav>
<div class="nav-wrapper teal darken-4">
BAZAART
<ul class="right hide-on-med-and-down">
<li><a class="waves-effect waves-light btn teal lighten-1" href="/home"> <i class="material-icons right">home</i> home</a></li>
<li><a class="waves-effect waves-light btn teal lighten-1" href="/profile">profile <i class="material-icons right">account_box</i></a></li>
</ul>
</div>
</nav>

Checkbox value is refreshed after page reload in node JS

"I am creating TODO list using Node as backend. after adding every new item, a checkbox is also generating in front of them so I can apply "CSS line-through" to let user know that item is done or of no use. But when I add another item, the page refreshes and that checkbox is unchecked as I am not storing that value anywhere. Can you tell me how to store the value of that checkbox in the backend?
HTML -
<div class="box" >
<% for (var i=0; i<newListItems.length; i++) { %>
<div class="item">
<input type="checkbox" id="checkBox">
<p> <%= newListItems[i] %> </p>
</div>
<% } %>
<form action="/" method="post" class="item">
<input class="inputBox" type="text" name="newItem" placeholder="New item" autocomplete="off" required="required">
<button type="submit" name="list" value=<%= listTitle%>> +</button>
</form>
</div>
Node JS -
const items = [];
app.post("/", function(req, res){
let item = req.body.newItem;
items.push(item);
res.redirect("/");
});
The answer involves a lot of code, so I will give you a set of steps that can help in your case.
You need to change your data scheme. Currently looks like you are just storing the string in an array of items. You need to change it to be array of objects. Each object should have the field task and done. So you could know which task is done or not.
app.post("/", function(req, res) {
let item = req.body.newItem;
items.push({ name: item, done: false });
res.redirect("/");
});
Next step will be adding an endpoint that will be changing the done field of an array item to true.
Then on a front-end you will need to write some JS code that will be sending an HTTP request to the endpoint that marks the task as done. You need to use AJAX call for that, for example, NPM package axios.
Change the template to reflect the changes to the data. e.g. instead of <%= newListItems[i] %> do <%= newListItems[i].name %> and add logic to render checked checkbox based on done property.
It worth to mention, that you should not store data in memory, because once the process is done, you will lose your data. It is okay for learning purposes, but in production, you should use a database.

Not being able to delete an item from to-do list using Item.removeOne( ) or Item.findByIdAndRemove( ) methods of mongoose in NodeJS

I am making a to-do list using mongodb,node.js,express and EJS. The part where I am stuck is I am not being able to delete and item from the list and the database. The idea is that on clicking a checkbox, the item beside will be deleted. Here is a layout for the same,
[https://i.stack.imgur.com/83gMW.png][1]
I made the necessary changes in my EJS file to create a "/delete" route as given below :
<%for(var i=0;i<taskslist.length;i++){%>
<form action="/delete" method="POST">
<div class="item">
<input type="checkbox" name="checkitem" value="<%= taskslist[i]._id %> " onChange="this.form.submit()">
<p><%= taskslist[i].activity %> </p>
</div>
</form>
<%}%>
In my app.js folder, I also made the necessary changes by using findByIdAndRemove( ) method for mongoose :
app.post("/delete", function (req, res) {
const delitem = req.body.checkitem;
Item.findByIdAndRemove(delitem, function (err) {
if (err) {
console.log("Error");
} else {
console.log("Succesfully deleted" + delitem);
res.redirect("/");
}
});
console.log(delitem);
});
However, the item is not getting deleted from the database and an error is showing in terminal, even though the console.log(delitem) is working and returning the id of the item whose checkbox is selected.
I am also giving a screenshot of the output I am getting at the terminal:

All the methods related to adding items and creating database are working. I don't understand where the error is. Please help me out with this.

Organizing view files in Node.js app

I finished this walkthrough for creating a very basic Reddit clone using the MEAN stack. The app included a few different views, such as a view for all posts, a single post, the login form, and the register form, and all of these views were included in a single file: views/index.ejs.
Is putting all the views together like this common practice, or was it merely for brevity in the tutorial? I was hoping to be able to separate at least the login and register forms from the rest of the views in index.ejs for the sake of organization, but placing them in a login.ejs file in views causes a 404.
Login portion of views/index.ejs
<script type="text/ng-template" id="/login.html">
<div class="page-header">
<h1>Flapper News</h1>
</div>
<div ng-show="error" class="alert alert-danger row">
<span>{{ error.message }}</span>
</div>
<form ng-submit="logIn()"style="margin-top:30px;">
<h3>Log In</h3>
<div class="form-group">
<input type="text" class="form-control" placeholder="Username" ng-model="user.username"></input>
</div>
<div class="form-group">
<input type="password" class="form-control" placeholder="Password" ng-model="user.password"></input>
</div>
<button type="submit" class="btn btn-primary">Log In</button>
</form>
</script>
Login portion of routes/index.js
router.post('/login', function(req, res, next){
if(!req.body.username || !req.body.password){
return res.status(400).json({message: 'Please fill out all fields'});
}
passport.authenticate('local', function(err, user, info){
if(err){ return next(err); }
if(user){
return res.json({token: user.generateJWT()});
} else {
return res.status(401).json(info);
}
})(req, res, next);
});
Login portion of controller
.state('login', {
url: '/login',
templateUrl: '/login.html',
controller: 'AuthCtrl',
onEnter: ['$state', 'auth', function($state, auth){
if(auth.isLoggedIn()){
$state.go('home');
}
}]
})
I don't understand how the views fit together in this app. What is telling the app to find the login template in index.ejs, and how can I redirect the app to look in a different file?
The way they did this is a little strange, but it was most likely for the sake of brevity.
The reason why it's 404'ing is because of how the routes are set up. There's a single route to serve index.ejs, and the rest of the routing is handled client-side through Angular. In fact, the only reason they used ejs is because they wanted to send it using Express' res.render() method most likely. (Although, since it's just HTML from what I saw, instead of actually using any EJS, they could likely just as easily used Express' res.sendFile() method, or prior to 4.8.0, res.send() in conjunction with Node's builtin fs.readFile to send the plain HTML file.
If you wanted to split out the views you'd have to set up server-side routes, but I guess they were dead set on a single-page app. More commonly, views that are rendered on the server-side are split out into individual files, with a main "layout", in which other views are included into.
