I am trying to use search product from DB, in nodejs but the product is not getting?

These are the products in MongoDB :(example)
product><<<<< [
{
_id: new ObjectId("62873c15c7becd09b1377fd8"),
Name: 'pixel 6',
Category: 'smart Phone',
Price: '60000',
Description: 'Note that to perform a smart search, DataTables uses regular expressions, so if enable regular expressions using the second parameter to this method, you will likely want to disable smart searching as the two regular expressions might otherwise conflict and cause unexpected results.',
Brand: 'Google'
},
{
_id: new ObjectId("628795e6a55d421aaca788cb"),
Name: 'iphone 11 pro ',
Category: 'smartphone',
Price: '100000',
Brand: 'apple',
Description: 'something'
}

I am trying to search product from DB, in nodejs but the product is not getting???
here is my code:
this is my search container in my header
user-header.hbs
<div class="search-container">
<form class="form-inline" action="/search" method="get">
<input class="search-input" id="search-box" type=" search" placeholder="Search..." name="searchTerm"
aria-label="Search" />
</form>
</div>
user.js
// GET: search box
router.get("/search",async (req, res) => {
try {
let searchTerm = req.body.searchTerm;
let user = req.session.user;
let product= await productHelpers.getAllProducts({Name:{ $search: searchTerm,$options: "i", $diacriticSensitive: true }});
res.render('user/search',{product,user});
console.log('searchTerm>',searchTerm)
console.log('products>',product)
} catch (error) {
res.status(500).send({message: error.message || "Error Occured" });
res.redirect("/");
}
});
user-helpers.js
from user-helpers geting all products fron collections
getAllProducts:()=>{
return new Promise(async(resolve,reject)=>{
let products=await db.get().collection(collection.PRODUCT_COLLECTION).find().toArray()
resolve(products)
})
},
search.hbs
Search result not getting
<h1 class="pb-4">Search Results</h1>
<div class="row row-cols-2 row-cols-lg-5 g-2 g-lg-3">
<a href="/" class="col text-center category__link">
<div class="category__img category__img--large shadow">
<img src="/product-images/{{product._id}}.jpg" alt="{{product.Name}}" loading="lazy">
</div>
<div class="pt-1">
{{products.Name}} </div>
</a>
</div>
my Assumption in user.js something wrong with the code!

Let me guess!
The name of the field you want to search is "Name"?
If so! then have you created text index in the collection on the "Name"
field?
And shouldn't the syntax be like {$text: { $search: searchTerm }}

Loop Through all users to send email Node JS

I tried finding the answer but couldn't. I'm new to Node Js and have a user schema that includes users emails. I want to have a form that has 'subject' and 'message' fields, and a submit button which would then send the contents of the form in an email. I'm currently using Mailgun, and a standard email looks like this:
var data = {
to: user.email,
from: '"Lighthouse Studios" <noreply#reception.lighthousespace.co.uk>',
subject: 'Your password has been changed',
text: 'Hello,\n\n' +
'This is a confirmation that the password for your account ' + user.email + ' has just been changed.\n'
};
mailgun.messages().send(data, function (error, body) {
console.log(body);
});
And my user schema looks like:
var UserSchema = new mongoose.Schema({
username: {type: String, unique: true, required: true},
name: {type: String, required: true},
email: {type: String, unique: true, required: true},
password: String,
studio: {type: String, required: true},
resetPasswordToken: String,
resetPasswordExpires: Date,
comments: [
{
quantity: String,
received: { type: Date, default: Date.now },
collected: { type: String, default: "At Reception" }
}
],
isAdmin: {type: Boolean, default: false}
});
Here's the form code:
<form action="/" method="POST">
<div class="form-group">
<input class="form-control" type="text" name="subject" placeholder="Subject">
</div>
<div class="form-group">
<textarea class="form-control" rows="5" id="comment" name="message" placeholder="Message"></textarea>
</div>
<div class="form-group">
<input class="btn btn-lg btn-primary btn-block" type="submit" value="Send">
</div>
</form>
So to summarise, I want to use the form to send all users an email when the button 'submit' is clicked. Thanks for your time reading this.

UserModel.find({})
.select('email')
.lean()
.exec((err,users)=>{
if(users){
let userEmails = "";
let recp = users.reduce((a,u)=>{ a[u.email]={}; a[u.email].email = u.email; userEmails+=u.email; return a; },{})
let data = {
to: userEmails,
from: '"Lighthouse Studios" <noreply#reception.lighthousespace.co.uk>',
subject: 'Your password has been changed',
text: 'Hello,\n\n' +'This is a confirmation that the password for your account ' + %recipient.email% + ' has just been changed.\n',
'recipient-variables': JSON.stringify(recp)
};
mailgun.messages().send(data, function (error, body) {
console.log(body);
});
}
})
Hope this one will work

MethodOverride PUT not working

I am using Node.js, Express and MethodOverride to try and have a form update only 1 part of a model (my user model).
User model:
var userSchema = new mongoose.Schema({
email: { type: String, unique: true, lowercase: true },
password: String,
profile: {
name: { type: String, default: 'Company Name' },
location: { type: String, default: 'Location' },
website: { type: String, default: 'Your Website' },
picture: { type: String, default: '' }
},
assetNumPre: { type: String, default: 'test' }, // this is the one I want to change
});
module.exports = mongoose.model('User', userSchema);
HTML form:
<form role="form-inline"action="/dashboard/settings/assetNumber?_method=PUT" method="POST">
<div class="col-md-3">
<div class="form-group">
<label for="prefix" class="control-label">Prefix for Asset Number</label>
<br>
<small>Any alphanumeric characters to a limit of 6</small>
<input type="text" class="form-control" id="prefix" name="prefix" placeholder="Prefix max 6 characters" maxlength="6" value="{{ prefix }}">
</div><!-- Prefix for Asset Number-->
<br>
<div class="box-footer">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
Then route:
app.put('/dashboard/settings/assetNumber',
setRender('dashboard/settings/assetNumbers'),
setRedirect({auth: '/login'}),
isAuthenticated,
dashboard.getDefault,
(req, res) => {
var prefix = req.body.prefix;
console.log(req.params);
User.findByIdAndUpdate({_id: req.params.user_id}, prefix, function(err, UpdatedUser) {
if (err) {
res.send(err);
}
console.log(UpdatedUser);
});
res.locals.prefix = req.user.assetNumPre;
});
One thing my route is missing is req.user.assetNumPre which is where I need to save it but I have no clue how to do this PUT request. Docs are not helping much either.
I got the route from a Stack Overflow example a few days ago and can't find the link to it. My app.js had method override working because I have done DELETE requests already. The model has the correct field and has a default test value that shows up in my show page.

You're calling this:
User.findByIdAndUpdate({_id: req.params.user_id}, prefix...
But prefix is only the value:
var prefix = req.body.prefix;
findByIdAndUpdate takes an Object, not a value, to update a specific field.
So try:
User.findByIdAndUpdate({_id: req.params.user_id}, { assetNumPre: prefix }...

Here is the fixed route:
app.put('/dashboard/settings/assetNumber',
setRedirect({auth: '/login', success: '/dashboard/settings/assetNumber', failure: '/dashboard/settings/assetNumber'}),
isAuthenticated,
(req, res) => {
User.findById(req.user.id, function(err, user) {
if (err) return (err);
user.assetNumPre = req.body.prefix || 'pre';
user.save(function(err) {
if (err) return (err);
req.flash('success', { msg: 'Asset Number Prefix updated.' });
res.redirect(req.redirect.success);
});
});
res.locals.prefix = req.user.assetNumPre;
});
So a few things changed that were not part of the issue. I figured out I need to just set the data inside the callback function. Then do a user.save.

how do i store ng-repeat array form data in meanjs?

I am using MEANJS from meanjs.org.
trying to store ng-repeat array data for deal which has dealtype and dealprice as array under it, but unable to do so.
i have setup addFields for the ng-repeat input tag in the create form, but it does not store the data. here is my code.
food.server.model.js
var FoodSchema = new Schema({
created: {
type: Date,
default: Date.now
},
name: {
type: String,
default: '',
required: 'Please fill Food name',
trim: true
},
deal: [{
dealtype: {
type: String,
default: '',
trim: true
},
dealprice: {
type: String,
default: '',
trim: true
}
}],
user: {
type: Schema.ObjectId,
ref: 'User'
}
});
foods.client.controller.js
// initial array setup
var deal = [ { dealtype: '',dealprice: '' }, {dealtype: '',dealprice: '' } ];
$scope.food = {};
$scope.food.deal = deal;
$scope.addItem = function() {
$scope.food.deal.push({
dealtype: '',
dealprice: ''
});
};
// Create new Food
$scope.create = function (isValid) {
$scope.error = null;
if (!isValid) {
$scope.$broadcast('show-errors-check-validity', 'foodForm');
return false;
}
// Create new Food object
var food = new Foods({
name: this.name,
deal:[{
dealtype: this.dealtype,
dealprice: this.dealprice,
}],
});
// Redirect after save
food.$save(function (response) {
$location.path('foods/' + response._id);
// Clear form fields
$scope.name = '';
$scope.dealtype = '';
$scope.dealprice = '';
}, function (errorResponse) {
$scope.error = errorResponse.data.message;
});
};

Try to set your schema up without the embedded array and send without deal. If that works you may need to set up your schema with a subdocument.
If you are wanting to set your deal property up as a Subdocument you would need to follow this. You would define a schema for deal separately. Something like this:
var dealSchema = new Schema({ {
dealtype: {
type: String,
default: '',
trim: true
},
dealprice: {
type: String,
default: '',
trim: true
}
} });
var FoodSchema = new Schema({
...,
deal: [dealSchema]
})

How to add an array to a javascript server side model in MEAN.JS

I am using MEAN.JS and I have created a module for projects. I would like to add tasks to these projects and I would like to do it with a multi-dimensional array. I would like the array to include a task.description and a task.status which would both be strings. I think I understand the client-side part of my project and I know there are still other files. However, I believe this will make the question as simple as possible, as I am struggling to get my profile developed on this site. I will however include controller.js, so I can get this working and hopefully give credit for a correct answer.
project.server.model.js
'use strict';
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
/**
* Project Schema
*/
var ProjectSchema = new Schema({
created: {
type: Date,
default: Date.now
},
title: {
type: String,
default: '',
trim: true,
required: 'Title cannot be blank'
},
description: {
type: String,
default: '',
trim: true
},
/* MODEL for TASK ARRAY*/
task: {
},
user: {
type: Schema.ObjectId,
ref: 'User'
}
});
mongoose.model('Project', ProjectSchema);
projects.server.controller.js
'use strict';
/**
* Module dependencies.
*/
var path = require('path'),
mongoose = require('mongoose'),
Project = mongoose.model('Project'),
errorHandler = require(path.resolve('./modules/core/server/controllers/errors.server.controller'));
/**
* Create a project
*/
exports.create = function (req, res) {
var project = new Project(req.body);
project.user = req.user;
project.save(function (err) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
res.json(project);
}
});
};
/**
* Show the current project
*/
exports.read = function (req, res) {
res.json(req.project);
};
/**
* Update a project
*/
exports.update = function (req, res) {
var project = req.project;
project.title = req.body.title;
project.description = req.body.description;
project.save(function (err) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
res.json(project);
}
});
};
edit-project.client.view.html
<section ng-controller="ProjectsController" ng-init="findOne()">
<div class="page-header">
<h1>Edit Project</h1>
</div>
<div class="col-md-12">
<form name="projectForm" class="form-horizontal" ng-submit="update(projectForm.$valid)" novalidate>
<fieldset>
<div class="form-group" show-errors>
<label for="title">Title</label>
<input name="title" type="text" ng-model="project.title" id="title" class="form-control" placeholder="Title" required>
<div ng-messages="projectForm.title.$error" role="alert">
<p class="help-block error-text" ng-message="required">Project title is required.</p>
</div>
</div>
<div class="form-group">
<label for="description">Description</label>
<textarea name="description" ng-model="project.description" id="description" class="form-control" cols="30" rows="4" placeholder="Description"></textarea>
</div>
<div class="form-group">
Task Description
<textarea name="description" ng.model="project.task.description" class="form-control" cols="30" rows="3" placeholder="Description"></textarea>
<div>
Task Status
<input name="status" ng.model="project.task.status" class="form-control" placeholder="Status">

</div>
<div ng-show="error" class="text-danger">
<strong ng-bind="error"></strong>
</div>
</fieldset>
</form>
</div>
</section>

First, create a model for tasks (task.server.model.js), which references a Project
var TaskSchema = new mongoose.Schema({
description: String,
status: String,
// referencing Project model
project: { type: mongoose.Schema.Types.ObjectId, ref: 'Project' }
});
And then in Project model reference Task
// Add this to Project Schema definition
tasks: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Task' }]

It's should
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
/**
* Task Schema
*/
var TaskSchema = new Schema({
description: String,
status: String,
project: {
type: Schema.ObjectId,
ref: 'Project'
}
});
Hope it's help you!
