How to parse field name using laravel - arrays

My Controller Code:
public function usersGroups(Request $request)
{
$resultArray = [];
$users = DB::table('users')
->join('user_basic_info','users.id','=','user_basic_info.user_id')
->select('users.id','user_basic_info.first_name')->get();
$resultArray['users'] = $users;
$groups = DB::table('group')
->select('group.id','group.name')->get();
$resultArray['groups'] = $groups;
return \Illuminate\Support\Facades\Response::json($resultArray, 200);
}
My Response:
{
"users": [
{
"id": 1,
"first_name": "Admin"
},
{
"id": 2,
"first_name": "Admin"
},
{
"id": 3,
"first_name": "Admin"
},
{
"id": 4,
"first_name": "Admin"
}
],
"groups": [
{
"id": 1,
"name": "Our Lira"
},
{
"id": 2,
"name": "CM"
}
]
}
here i there is field name first_name and i want to change it to name without changing the field name in table just for this API i want to change first_name to name.
How i can achieve this?
Your help needs here

You can simply make an alias using MySQL:
$users = DB::table('users')
->join('user_basic_info','users.id','=','user_basic_info.user_id')
->select('users.id','user_basic_info.first_name as name')->get();
Notice the as name in the select query.

Use an API Resource
These are classes that let you transform your models to whatever JSON format/layout you want.

i am not so good in api but you can achive it through setting alaias name
public function usersGroups(Request $request)
{
$resultArray = [];
$users = DB::table('users')
->join('user_basic_info','users.id','=','user_basic_info.user_id')
->select('users.id','user_basic_info.first_name as name')->get();
$resultArray['users'] = $users;
$groups = DB::table('group')
->select('group.id','group.name')->get();
$resultArray['groups'] = $groups;
return \Illuminate\Support\Facades\Response::json($resultArray, 200);
}
Can You try this if there is any error kindly comment below

How filter and delete object with null or empty property in json query

I have this json :
{
"meta": {
"status": 200,
"pagination": {
"page": 1,
"perPage": 15,
"hasNext": true
}
},
"data": [
{
"id": "1",
"title": "Movie title1"
"rating": null,
"playProviders": [
]
},
{
"id": "2",
"title": "Movie title2"
"rating": {
"ratingAssessment": "7.1"
},
"playProviders": [
"HBO", "Netflix"
]
},
....
}
I want to create a page with a list of movies, I need to fetch movies but only those which have a rating and playProviders, what parameters should I use in this request?
https://api.com/movies?orderBy=views
When I filters in the code:
programs.filter((program) => program.rating !== null);
it only gets a few films per page, those that don't have null. For example, 15 are per page and I get 2. How do I filter this? (I am using react typescript)
I don't have access to the API code. I need to filter what is returned by the API or write a query so that you get already filtered data from the API.
programs = [
{rating: 1,
playProviders: ["sf"]
},
{
rating: 4,
playProviders: []
}
]
programs.filter(function(program) {
if (program.rating !== null && program.playProviders.length !== 0) {
return program;
}
})

Cakephp How Can I add virtual field in select query?

In front end I have to display all favorites icon green depend on is_fav status true.
So, I'm trying to create an API, Where I want to add is_fav with all product entity. My expected json will looks like
{
"id": 14,
"title": "Orange",
"price": 600,
"is_fav" : true
}
So, I'm trying to add is_fav with product entities , where is_fav is a virtual function.
In entity I have tried like below
protected function _getIsFav()
{
//to DO : I will write a query here
return true;
}
In query I have tried to add in query in select like below
$favorites = TableRegistry::getTableLocator()
->get( 'Products' )
->find()
->select([
'id',
'Products.id',
'Products.title',
'Products.price',
'is_fav' => $this->is_fav, //getting error
])
;
I'm getting error, How can I add is_fav with product entities. Is it possible ? If not how can I add is_fav like my json ?
This worked for me. CakePHP 4.3
In the Entity
protected $_virtual = ['label'];
protected function _getLabel()
{
return $this->name . ' - (' . $this->company. ')';
}
The query does not mention the virtual field
$customers = $this->Users->find()
->select(['id', 'name', 'company'])
->contain(['Roles' => function ($q) {
return $q->select(['id','name','level','price_level'])
->where(['Roles.level' => 50]);
}])
->order('Users.name');
and then the JSON that output
[
{
"id": 1019,
"name": "Abby xxxx",
"company": "Abby yyy",
"role": {
"id": 4,
"name": "Practitioner",
"level": 50,
"price_level": 2
},
"label": "Abby xxxx - (Abby yyy)"
}
]

Laravel how to return object into JSON Arrays data type without keys

I have DB query in the Controller like this:
$query = User::all('id','name','email')->take(2);
$users = ["data" => $query];
return $users;
And get the result:
{
"data": [
{
"id": 1,
"name": "Peter",
"email": "peter#peter.com"
},
{
"id": 2,
"name": "John",
"email": "john#john.com"
}
]
}
But i'm expecting to get JSON Arrays data type without keys like this:
{
"data": [
[
"1",
"Peter",
"peter#peter.com"
],
[
"2",
"John",
"john#john.com"
]
]
}
I need to get this type for DataTables JSONP data source for remote domains.
https://datatables.net/examples/server_side/jsonp.html
How to do this?
Thanks.
You can try array_values like so:
$query = User::all('id', 'name', 'email')->take(2);
$users = ["data" => $query->map(function (User $user) {
return array_values($user->attributesToArray());
})];
return $users;
How about something like this?
$query = User::all('id', 'name', 'email')->take(2);
$userValues = $query->map(function($item, $key) {
return [
$item['id'],
$item['name'],
$item['email']
];
})
$users = ["data" => $userValues];
return $users;
// result
{
"data": [
[
1,
"Amy Wilderman",
"vrau#example.net",
],
[
2,
"Bria Lindgren PhD",
"trevor.armstrong#example.org",
],
]
}

$loaded is not working properly when the server data is changed

I am new to firebase and angularjs. For my sales application I would like to use both. So, in my app I am using AngularJS v1.5.8 + Firebase v3.3.0 + AngularFire 2.0.2. I have sales and users objects in firebase db, and has a business logic that one user can sell multiple products, but one product can have only one owner (user).
Here is the users and sales objects in database:
{
"sales" : {
"-KQlb5N6A9rclc5qcWGD" : {
"price" : 8,
"quantity" : {
"count" : 12,
"type" : "porsiyon"
},
"status" : "sale",
"title" : "Patlicanli Borek",
"user" : "-KQ52OJd-lwoDIWzfYFT"
},
"-KQlcScsq8cidk7Drs04" : {
"price" : 12,
"quantity" : {
"count" : 10,
"type" : "porsiyon"
},
"status" : "sale",
"title" : "Deneme",
"user" : "-KQ5-mZBt6MhYy401gGM"
},
"-KQzXHwOv2rC73scjV46" : {
"price" : 12,
"quantity" : {
"count" : 11,
"type" : "porsiyon"
},
"status" : "sale",
"title" : "Pacanga",
"user" : "-KQ5-mZBt6MhYy401gGM"
},
"-KSCBgpArtnKunUuEuVr" : {
"price" : 15,
"quantity" : {
"count" : 15,
"type" : "porsiyon"
},
"status" : "sale",
"title" : "Iskembe",
"user" : "-KQ52OJd-lwoDIWzfYFT"
}
},
"users" : {
"-KQ5-mZBt6MhYy401gGM" : {
"address" : "Halkali kucukcekmece",
"email" : "burak.kahraman#gmail.com",
"name" : "Burak Hero",
"nick" : "Burak'in Mutfagi"
},
"-KQ52OJd-lwoDIWzfYFT" : {
"address" : "Izmir kaynaklar",
"email" : "ayse#gmail.com",
"name" : "Ayse Kahraman",
"nick" : "Ayse'nin Mutfagi"
}
}
}
What I want to do is when my app is opened, it will show all sales together with corresponding user details. (just like main page of letgo application) Which means I should implement a simple join between sales and users objects. As far as I searched throughout internet and api docs, there is no way to implement this kind of join in a single call to firebase. (Pl correct me if I am wrong) So I used below method with using $loaded function inside of my SalesService to implement join.
angular.
module('core.sales')
.service('SalesService', function ($firebaseArray, $firebaseObject, UsersService) {
this.getAllSalesJoin = function () {
var sales;
var refSales = firebase.database().ref('sales');
sales = $firebaseObject(refSales);
sales.$loaded()
.then(function () {
angular.forEach(sales, function (sale) {
var saleUser = UsersService.getUserDetail(sale.user);
saleUser.$loaded()
.then(function () {
sale.user = saleUser;
});
});
});
return sales;
};
});
As you see I am fetching all sales, after it finishes, looping for each sale to get and set related user detail by calling another UsersService shown below
angular.
module('core.users')
.service('UsersService', function ($firebaseArray,$firebaseObject) {
this.getUserDetail = function (userId) {
var user;
var refUser = firebase.database().ref('users/'+userId);
user = $firebaseObject(refUser);
return user;
};
});
So far so good, when I call SalesService.getAllSalesJoin function within my Controller and print the JSON object using <pre>{{$ctrl.allSales | json}}</pre>, everything works as I wanted, below is the Controller code and printed JSON object in the template.
angular.
module('saleList').
component('saleList', {
templateUrl: 'MCTs/sale-list/sale-list-template.html',
controller: ['SalesService','UsersService', function SaleListController(SalesService,UsersService,$scope) {
this.allSales = SalesService.getAllSalesJoin();
}]
});
Template shows the merged objects
{
"$id": "sales",
"$priority": null,
"-KQlb5N6A9rclc5qcWGD": {
"price": 8,
"quantity": {
"count": 12,
"type": "porsiyon"
},
"status": "sale",
"title": "Patlicanli Borek",
"user": {
"$id": "-KQ52OJd-lwoDIWzfYFT",
"$priority": null,
"address": "Izmir kaynaklar",
"email": "ayse#gmail.com",
"name": "Ayse Kahraman",
"nick": "Ayse'nin Mutfagi"
}
},
"-KQlcScsq8cidk7Drs04": {
"price": 12,
"quantity": {
"count": 10,
"type": "porsiyon"
},
"status": "sale",
"title": "Deneme",
"user": {
"$id": "-KQ5-mZBt6MhYy401gGM",
"$priority": null,
"address": "Halkali kucukcekmece",
"email": "burak.kahraman#gmail.com",
"name": "Burak Hero",
"nick": "Burak'in Mutfagi"
}
},
.....
But the problem is, when server data is changed (new sale is entered or old one is deleted), angular automatically understands the change but it applies the change to the view without implementing or calling my joined function, it simply prints only the sales object not the merged one with users. Below is the showing object after server data is changed.
{
"$id": "sales",
"$priority": null,
"-KQlb5N6A9rclc5qcWGD": {
"price": 8,
"quantity": {
"count": 12,
"type": "porsiyon"
},
"status": "sale",
"title": "Patlicanli Borek",
"user": "-KQ52OJd-lwoDIWzfYFT"
},
"-KQlcScsq8cidk7Drs04": {
"price": 12,
"quantity": {
"count": 10,
"type": "porsiyon"
},
"status": "sale",
"title": "Deneme",
"user": "-KQ5-mZBt6MhYy401gGM"
},
....
I am confused why it behaves like that? Is my way to implement join using $loaded wrong? Or should I use another method to implement this kind of join? I am looking forward to see your priceless suggestions and ideas.
$loaded() only fires when the initial data has loaded. From the reference documentation (emphasis mine):
Returns a promise which is resolved when the initial object data has been downloaded from the database.
This is the main reason I often say: "if you're using $loaded(), you're doing it wrong".
You're right about needing to join data with multiple calls. In AngularFire you can extend $firebaseArray to perform such an operation. For a great example of how to do this, see this answer by Kato: Joining data between paths based on id using AngularFire
Thank for the guide #Frank. I read all your suggestions and found the solution. For contributing stackoverflow knowledge and to help others here is the complete solution for the problem.
I first created a new factory that extends $firebaseArray and override $$added and $$updated methods to perform join to Users object each time when the data is updated or added.
angular.
module('core.sales').factory("SalesFactory", function ($firebaseArray, Sales) {
return $firebaseArray.$extend({
$$added: function (snap) {
return new Sales(snap);
},
$$updated: function (snap) {
return this.$getRecord(snap.key).update(snap);
}
});
});
angular.
module('core.sales').factory("Sales", function ($firebaseArray, $firebaseObject) {
var refUsers = firebase.database().ref('users');
function Sales(snapshot) {
this.$id = snapshot.key;
this.update(snapshot);
}
Sales.prototype = {
update: function (snapshot) {
var oldTitle = angular.extend({}, this.title);
var oldPrice = angular.extend({}, this.price);
var oldQuantity = angular.extend({}, this.quantity);
this.userId = snapshot.val().user;
this.title = snapshot.val().title;
this.status = snapshot.val().status;
this.price = snapshot.val().price;
this.quantity = snapshot.val().quantity;
this.userObj = $firebaseObject(refUsers.child(this.userId));
if (oldTitle == this.title && oldPrice == this.price &&
oldQuantity.count == this.quantity.count && oldQuantity.type == this.quantity.type)
return false;
return true;
},
};
return Sales;
});
As you see, SalesFactory uses another factory called Sales. In that particular factory I retrieve all properties of Sales object and assign each of them to its corresponding property. And that is the case I am performing join to Users object by creating new property : this.userObj
One thing is missing that is just calling the new Factory instead of $firebaseArray
this.getAllSalesArray = function () {
var sales;
var refSales = firebase.database().ref('sales');
sales = SalesFactory(refSales);
return sales;
};
All in all, all Sales object joined with related User is printed to the view is,
[
{
"$id": "-KQlb5N6A9rclc5qcWGD",
"userId": "-KQ52OJd-lwoDIWzfYFT",
"title": "Patlicanli Borek",
"status": "sale",
"price": 12,
"quantity": {
"count": 11,
"type": "tabak"
},
"userObj": {
"$id": "-KQ52OJd-lwoDIWzfYFT",
"$priority": null,
"address": "İzmir kaynaklar",
"email": "ayse#gmail.com",
"name": "Ayşe Kahraman",
"nick": "Ayşe'nin Mutfağı"
}
},
{
"$id": "-KQlcScsq8cidk7Drs04",
"userId": "-KQ5-mZBt6MhYy401gGM",
"title": "Deneme",
"status": "sale",
"price": 12,
"quantity": {
"count": 10,
"type": "porsiyon"
},
"userObj": {
"$id": "-KQ5-mZBt6MhYy401gGM",
"$priority": null,
"address": "Halkalı küçükçekmece",
"email": "burak.kahraman#gmail.com",
"name": "Burak Hero",
"nick": "Burak'ın Mutfağı"
}
},
...
]

$filter with custom function in angular

How I can create a $filter with custom function to determining if match ?
This is a json sample with structure:
$scope.routes =[
{
"id": 0,
"name": "Rosa Barnes",
"origin": [
{
"address": [
{
"locality": "Madrid",
"country": "ES"
}
]
}
]
},
{
"id": 1,
"name": "Wright Montoya",
"origin": [
{
"address": [
{
"locality": "London",
"country": "UK"
}
]
}
]
},
{
"id": 2,
"name": "Pearson Johns",
"origin": [
{
"address": [
{
"locality": "London",
"country": "UK"
}
]
}
]
}
];
I want a $filter that passing one country, match in origin.address.country , is possible?
I proved this code but not works:
$scope.routesToShow = $filter('filter')($scope.routes, {origin.address.country: "UK"});
Here there are a demo:
http://jsfiddle.net/86U29/43/
Thanks
What you need is a custom filter. It also looks like you might need to tweak your data structure too.
Take a look at this:
app.filter('CustomFilter', function () {
function parseString(propertyString) {
return propertyString.split(".");
}
function getValue(element, propertyArray) {
var value = element;
propertyArray.forEach(function (property) {
value = value[property];
});
return value;
}
return function (input, propertyString, target) {
var properties = parseString(propertyString);
return input.filter(function (item) {
return getValue(item, properties) == target;
});
}
});
You could use this filter, like this:
$scope.routesToShow = $filter('CustomFilter')($scope.routes, 'origin.address.country', 'UK');
Here is an updated jsfiddle (notice the updated data structure): http://jsfiddle.net/moderndegree/86U29/44/
You can find more information on creating custom filters here:
https://docs.angularjs.org/guide/filter#creating-custom-filters
Simply.
var filter = function(obj){
return obj.origin[0].address[0].country === 'UK';
}
$scope.routesToShow = $filter('filter')($scope.routes, filter);
