I'm actually creating an app for my neighborhood little business, y have this db schema using Postgresql:
https://res.cloudinary.com/dthhugesg/image/upload/v1569939688/nodejserror/lugarlov_schema_db_dykxnt.png
my use cases are:
1 user can create 1 experience.
1 user can create a business local only if its going to leave an experience from it.
1 experience can have several images.
( I haven't a relationship between business_locals and users because doesn't matter for who creates the business).
I haven't had problems untill now, I'm trying to get the business with it's name, lat and lng; the average score given by users, 1 image from the last experience where the name like = "somestring"
this are my models:
Business Model: https://res.cloudinary.com/dthhugesg/image/upload/v1569939688/nodejserror/lugarlov_businessmd_rwnsnu.png
Images model: https://res.cloudinary.com/dthhugesg/image/upload/v1569939688/nodejserror/lugarlov_imgaesmd_m4hkzv.png
experiencies model: https://res.cloudinary.com/dthhugesg/image/upload/v1569939688/nodejserror/lugarlov_experienciesmd_f7jtxt.png
y try this code:
export async function getBusinessByQueryString(req, res) {
let query = req.params.query;
const businessesResult = await Business.findAll({
where: Sequelize.where(
Sequelize.fn("LOWER", Sequelize.col("name")),
{
[Op.like]: `%${query}%`
}
),
attributes: ['name', sequelize.fn('COUNT', sequelize.col('experiencies.id'))],
include: [
{ model: Experiencies, attributes: [] }
],
group: ["business_locals.id"]
}).catch(err => {
return res.status(500).json({
ok: false,
messagge: "Error al consultar el comercio",
err
});
});
console.log(businessesResult);
// let businessIdArrays = businessesResult.map((obj) => obj.id);
// console.log(businessIdArrays);
return res.json({
ok: true,
message: businessesResult
});
}
but I'm having this error:
https://res.cloudinary.com/dthhugesg/image/upload/v1569939691/nodejserror/error_x0tsiq.png
I'm expecting this:

subjectlist::class,
department::class,
'id',
'course_id',

Relationship between your tables are like
Subject as a Course
Course has a Department
and Subject has a department through course
Relation For Your Subject Model
public function Course() {
return $this->belongsTo(Course::class);
}
public function Department() {
return $this->hasOneThrough(Department::class, Course::class)
}
Relation For Your Course Model
public function Subject() {
return $this->hasMany(Subject::class);
}
public function Department() {
return $this->belongsTo(Department::class);
}
Relation For Your Department Model
public function Course() {
return $this->hasMany(Course::class);
}

In a mongodb database with a master-detail structure, how do I ensure that the data in the detail table is grouped according to the status area while querying the master table. For example ...
Master, Row, Job, Fields, [Detail Status Grouped Count / Summary Object]

I experimented for approximately 4-5 hours. I could get the closest result with the following query.
db.getCollection("sms_jobs").aggregate([{
$lookup: {
from: "sms_job_details",
localField: "_id",
foreignField: "sms_job_id",
as: "data"
}
}, {
$unwind: "$data"
}, {
$group: {
_id: {
id: "$_id",
status: "$data.status"
},
qty: {
$sum: 1
}
}
}, {
$project: {
_id: "$_id.id",
qty: 1,
status: "$_id.status"
}
}])
And get this result :
// 1
{
"qty": 22145,
"_id": NumberInt("4"),
"status": "success"
}
// 2
{
"qty": 1,
"_id": NumberInt("3"),
"status": "success"
}
// 3
{
"qty": 22142,
"_id": NumberInt("1"),
"status": "success"
}
// 4
{
"qty": 1,
"_id": NumberInt("1"),
"status": "failed"
}
// 5
{
"qty": 2,
"_id": NumberInt("1"),
"status": "waiting"
}
// 6
{
"qty": 1,
"_id": NumberInt("3"),
"status": "failed"
}
// 7
{
"qty": 3,
"_id": NumberInt("3"),
"status": "waiting"
}
What do I want ?
The query result I want is as follows.
// 1

"sms_gateway_id": NumberInt("1"),

I am trying to loop through a JSON and append it to HTML in a nested way. What I am trying to do is add a Header tag for the title of the object and have tags for the titles of items. Some objects might not have the items as empty too. I am guessing a nested loop is required and I've tried implementing it. The JSON looks like:
[
{
"id": 1,
"title": "Hello",
"url": "http://localhost:8000/login/notes/1/",
"description": "Hello nice",
"created_at": "2019-08-10T06:02:55.468315Z",
"created_by": "Dude",
"items": [
{
"id": 1,
"url": "http://localhost:8000/login/items/1/",
"title": "baby's toy",
"note": "http://localhost:8000/login/notes/1/"
},
{
"id": 2,
"url": "http://localhost:8000/login/items/2/",
"title": "baby's toy",
"note": "http://localhost:8000/login/notes/1/"
},
{
"id": 4,
"url": "http://localhost:8000/login/items/4/",
"title": "postman5",
"note": "http://localhost:8000/login/notes/1/"
}
]
},
{
"id": 2,
"title": "abc",
"url": "http://localhost:8000/login/notes/2/",
"description": "asad",
"created_at": "2019-08-10T15:23:53.074848Z",
"created_by": "dude2",
"items": [
{
"id": 5,
"url": "http://localhost:8000/login/items/5/",
"title": "Parrot Toy",
"note": "http://localhost:8000/login/notes/2/"
}
]
}]
I've tried
fetch('http://localhost:8000/login/notes/?format=json',{mode: 'cors'})
.then(response => response.json())
.then(data => {
var output='';
var final='';
var semif='';
var darif='';
for (var i in data) {
output+=i+'<h2>'+data[i].title +'</h2>'
for(j in data[i].items){
final+='<li>'+data[i].items[j].title+'</li>'
}
semif=output+final
}
document.getElementById('test').innerHTML=darif
});
HTML
<p id="test">
</p>
What I want to achieve is:
<h1>Hello</h1>
<h5>baby's toy</h5>
<h5>baby's toy</h5>
<h5>postman5</h5>
<h1>abc</h1>
<h5>parrot's toy</h5>
I strongly advise against doing lengthy string concatenations. Strings are immutable objects and they can put unnecessary burden on your system.
In addition, using map and join is much more elegant and easier to read.
const data = [
{
"id": 1,
"title": "Hello",
"url": "http://localhost:8000/login/notes/1/",
"description": "Hello nice",
"created_at": "2019-08-10T06:02:55.468315Z",
"created_by": "Dude",
"items": [
{
"id": 1,
"url": "http://localhost:8000/login/items/1/",
"title": "baby's toy",
"note": "http://localhost:8000/login/notes/1/"
},
{
"id": 2,
"url": "http://localhost:8000/login/items/2/",
"title": "baby's toy",
"note": "http://localhost:8000/login/notes/1/"
},
{
"id": 4,
"url": "http://localhost:8000/login/items/4/",
"title": "postman5",
"note": "http://localhost:8000/login/notes/1/"
}
]
},
{
"id": 2,
"title": "abc",
"url": "http://localhost:8000/login/notes/2/",
"description": "asad",
"created_at": "2019-08-10T15:23:53.074848Z",
"created_by": "dude2",
"items": [
{
"id": 5,
"url": "http://localhost:8000/login/items/5/",
"title": "Parrot Toy",
"note": "http://localhost:8000/login/notes/2/"
}
]
}]
const result = data.map(el => {
return `<h1>${el.title}</h1>` + el.items.map(el => `<h5>${el.title}</h5>`).join("")
}).join("")
console.log(result)
fetch('http://localhost:8000/login/notes/?format=json',{mode: 'cors'})
.then(response => response.json())
.then(data => {
var html = '';
data.forEach(listItem => {
const h1 = `<h1> ${listItem.title} </h1>`;
html+=h1;
listItem.items.forEach(item=> {
const h5 = `<h5> ${item.title} </h5>`;
html+=h5;
});
});
document.getElementById('test').innerHTML=html;
});
I think you may use it.

I am facing issue in merging two object. Below is the snap of two object and result.
Here in the above image I wan to merge Old Data and new Data
but after merging getting wrong output i.e new updated data.
I am using command to do it.
let newData = { ...a , ...b }
console.log('new updated data: ',newData)
also I am performing this operation in redux action before dispatching.
Here {"activities": [....],....} is one object and I want to merge with the below one.
Can you clarify do your objects have a child that are objects or arrays and if you mean it's not merging those things or is it not merging anything at all?
for e.g:
let oldData = {
key: value,
key1: { childkey1: value1 }
}
if you have something like this and the problem is like I explained. It's because javascript doesn't do deep merge. it does a shallow merge.
Easiest option would be use a library like lodash that has a function for deep merge.
all. I'm new with Angular. I need to find out how to save my JSON changes after push.
app.controller('ReviewController', function(){
this.r = {};
this.addReview = function(product){
this.r.createdOn = Date.now();
product.reviews.push(this.r);
this.r = {};
};
});
also I have this thing, where I get JSON data. I don't know if it would be useful for you to know that
app.factory('events', function($http) {
return function(){
return $http.get('products.json');
};
});
app.controller("StoreController", function(events){
var store = this;
store.products = [];
events().success(function(data) {
store.products = data;
});
One more thing. My products.json file:

The are some ways to do this
First : You can create a button say called "save changes", and tell the user after finishing the process of adding new data with your so-called function addReview, Hit the save changes , and in the on-click of this button , you can create a $http.post request and send your new pushed array into your database (or your json file , whatever it is)
Second : You can do the same $http.post in your own function , addReview, without creating a button and listening for user to click on save changes button.
For example:
if you want to go for my second solution :
this.addReview = function(product){
this.r.createdOn = Date.now();
product.reviews.push(product);
this.r = {};
$http.post('yourServerFile',WhateverYouWantToSave)
.success(function(){
alert('Your Changes have been saved to database');
})
};
//Dont forget to inject $http into your controller
And its better to define a factory/servise for this kind of theories(pushing/adding/sending/deleting somethig from somewhere)
