In controller get data from db like this, I want to pass whole of $request to another function in this controller to get price it calculating price based of many things from $request:
$user = Auth::user();
$query = Post::query();
$query
->where('province', '=', $user->province)
->where('city', '=', $user->city);
$customers = $query->get();
$customers['calculator'] = $this->calculator($request); // call function
my problem is it return like this:
{
"0": {
"id": 1,
"hash": "RqH29tkfm1dwGrXp4ZCV",
},
"1": {
"id": 3,
"hash": "RqH29tkfm1dwGsXp4ZCV",
},
"calculator": {
"price": 1
}
}
But I need to use that function for each data, and result should be like this:
{
"0": {
"id": 1,
"hash": "RqH29tkfm1dwGrXp4ZCV",
"calculator": {
"price": 1
}
},
"1": {
"id": 3,
"hash": "RqH29tkfm1dwGsXp4ZCV",
"calculator": {
"price": 1
}
}
}
What you want is to set a calculator key for each item in the $customers collection. So you need to loop over it:
foreach ($customers as $customer) {
$customer->calculator = $this->calculator($request);
}
Notice that since the $customer is a Model you should set the calculator as a property. Internally it will be set to the attributes array.

I have some struggles how to map infinite object in Laravel.
So I have one table Categories that I'm getting in controller like:
$find_parent = Category::where('slug', $slug)->with('childrenRecursive')->first();
childrenRecursive() works fine in that case.
And return of this object would be like (minified):
{
"id": "1cbd459a-ccc0-435b-b9a9-0433e2e9285b",
"parent_id": "f0d29100-d2bc-48c8-89cf-985e0c03b8ac",
"children_recursive": [
{
"id": "30bf23a7-b28c-4s78-b873-1df589eebcb1",
"parent_id": "1cbd459a-ccc0-435b-b9a9-0433e2e9285b",
"children_recursive": [
{
"id": "32312a7-b28c-4s78-b873-1df589eebcb1",
"parent_id": "30bf23a7-b28c-4s78-b873-1df589eebcb1",
}
]
},
{
"id": "32bf23a7-b28c-4s78-b873-1df589eebcb1",
"parent_id": "1cbd459a-ccc0-435b-b9a9-0433e2e9285b",
"children_recursive": []
}
]
}
So from this, I have to get all id's in every object. So I have foreach function in controller that looks like:
$find_parent = Category::where('slug', $slug)->with('childrenRecursive')->first();
$array = [];
foreach($find_parent->childrenRecursive as $l){
array_push($array, $l->id);
if($l->childrenRecursive){
$result = array_merge($array, $this->catTree($l->childrenRecursive));
}
}
return $result;
And catTree would look like:
public function catTree($list){
$tree = [];
foreach($list as $l){
array_push($tree, $l->id);
if($l->childrenRecursive){
array_merge($tree, $this->catTree($l->childrenRecursive));
}
}
return $tree;
}
So this is returning some of the objects, but not everything. What am I doing wrong here?
I have the following which I would like to order alphabetically by the Key i.e first for each array group would be "bname", followed by "created_at".
{
"leads": [
{
"lead_id": 1,
"zoho_lead": null,
"bname": "ABC Limited",
"tname": "ABC",
"source_id": 11,
"industry_id": 1,
"user_id": 1,
"created_at": "2017-09-06 15:54:21",
"updated_at": "2017-09-06 15:54:21",
"user": "Sean McCabe",
"source": "Unknown",
"industry": "None"
},
{
"lead_id": 2,
"zoho_lead": 51186111981,
"bname": "Business Name Limited",
"tname": "Trading Name",
"source_id": 11,
"industry_id": 1,
"user_id": 1,
"created_at": "2017-06-01 12:34:56",
"updated_at": null,
"user": "John Doe",
"source": "Unknown",
"industry": "None"
}
]
}
I'm trying to use ksort like so in the foreach loop:
class LeadController extends Controller
{
use Helpers;
public function index(Lead $leads)
{
$leads = $leads->all();
foreach($leads as $key => $lead){
$lead->user = User::where('id', $lead->user_id)->first()->name;
$lead->source = Source::where('id', $lead->source_id)->first()->name;
$lead->industry = Industry::where('id', $lead->industry_id)->first()->name;
$lead->ksort();
}
return $leads;
}
But I get the following error:
Call to undefined method Illuminate\\Database\\Query\\Builder::ksort()
How do I use this function, or is there a Laravel way of doing this, or a better way altogether?
Thanks.
Managed to get it to return with the Keys in alphabetical order, so below is the solution in-case someone else should require it:
public function index(Lead $leads)
{
$leadOut = Array();
$leads = $leads->all();
foreach($leads as $key => $lead){
$lead->user = User::where('id', $lead->user_id)->first()->name;
$lead->source = Source::where('id', $lead->source_id)->first()->name;
$lead->industry = Industry::where('id', $lead->industry_id)->first()->name;
//Convert to Array
$leadOrder = $lead->toArray();
//Sort as desired
ksort($leadOrder);
//Add to array
$leadOut[] = $leadOrder;
}
return $leadOut;
}
There is likely a cleaner way to do this, but it works for my instance, and perhaps additional answers may be posted that are better.
You could do something like:
return Lead::with('user', 'source', 'industry')->get()->map(function ($lead) {
$item = $lead->toArray();
$item['user'] = $lead->user->name;
$item['source'] = $lead->source->name;
$item['industry'] = $lead->industry->name;
ksort($item);
return $item;
});
This should be much more efficient as it will eager load the relationships rather than make 3 extra queries for each iteration.
I have a laravel query builder result that looks like this
{
"data": [
{
"id": "",
"awardID": 2,
"title": "Dummy title",
"status": "active",
"raceStart":"",
"raceEnd:":""
}
]
}
What i want to output is something like this
{
"data": [
{
"id": "",
"awardID": 2,
"title": "Dummy title",
"status": "active",
"period": {
"raceStart":"",
"raceEnd:":""
}
}
]
}
This would have been much easier if the period was a table with a 1 to 1 relationship with parent table but this is not the case here.
How can this be achieved?
Check if this will work. I haven't tried though but according to documentation we can add accessor and mutators. But it will change every response you are doing with the model.
Using Eloquent
// Your Model
class Race extends Model
{
{...}
protected $appends = ['period'];
// accessor
public function getPeriodAttribute($value)
{
$this->attributes['period'] = (object)[];
$this->attributes['period']['raceStart'] = $this->attributes['raceStart'];
$this->attributes['period']['raceEnd'] = $this->attributes['raceEnd'];
unset($this->attributes['raceStart']); = $value;
unset($this->attributes['raceEnd']);
return $this->attributes['period'];
}
}
Now when you will access $race->period will give the raceStart and raceEnd value.
Ref: https://laravel.com/docs/5.4/eloquent-mutators#accessors-and-mutators
else another option is after query, do a map
{...}
->map(function($data) {
$data->period = (object)[];
$data->period['raceStart'] = $data->raceStart;
$data->period['raceEnd'] = $data->raceEnd;
unset($data->raceStart);
unset($data->raceEnd);
return $data;
});
Ref: https://laravel.com/docs/5.4/eloquent-collections#introduction
Using QueryBuilder
$races = DB::table('races')->get();
$races = array_map(function ($data) {
$data->period = (object)[
"raceStart" => $data->raceStart,
"raceEnd" => $data->raceEnd
];
unset($data->raceStart);
unset($data->raceEnd);
return $data;
}, $races->data);
I working on an API for my app.
I'm trying to pull items from the database and return them in JSON object,
my items table looks like this:
Items
-id
-name
-description
-price
-currency_id
-company_id
this is how I'm getting the items:
$rows = Company::where('guid',$guid)
->first()
->items()
->orderBy('name', $sort_order);
I want to replace the currency_id with a currency object that contains all the columns of currency table
so my result will be like this:
[
{
'id':'1',
'name':'name',
'description': 'example',
'price':'100',
'currency':{
'id':'1',
'name':'usd',
'symbol': '$'
}
}
]
update:
This is my currencies table:
id
name
symbol
code
Edit 2: The user's problem was more complex than this since there was pagination and search integration with the query. Helped with https://pastebin.com/ppRH3eyx
Edit : I've tested the code. So here.
In Company model
public function items()
{
return $this->hasMany(Item::class);
}
In Item model
public function currency()
{
return $this->belongsTo(Currency::class);
}
Controller logic
$items = Company::with(['items' => function($query) use ($sort_order) {
$query->with('currency')->orderBy('name', $sort_order);
}])
->where('guid', $guid)
->first()
->items;
Result with test data
[
{
"id": 2,
"name": "Toy",
"description": "Random text 2",
"price": 150,
"company_id": 1,
"currency_id": 1,
"currency": {
"id": 1,
"name": "usd",
"symbol": "$",
"code": "USD"
}
},
{
"id": 1,
"name": "Phone",
"description": "Random text",
"price": 100,
"company_id": 1,
"currency_id": 1,
"currency": {
"id": 1,
"name": "usd",
"symbol": "$",
"code": "USD"
}
}
]
Try this.
$rows = Company::with('items.currency')
->where('guid', $guid)
->first()
->items()
->orderBy('name', $sort_order);
Try below
Make one relationship in Item Model
public function currencies() {
return $this->hasMany('App\Currency');
}
then do below in your controller
$row=Items::All()->with('currencies');
I would like to flatten an object. This is what I've got so far:
{
"1": {
"id": 1,
"name": "parent",
"children": {
"4": {
"id": 4,
"name": "child1",
"parent": 1
},
"5": {
"id": 5,
"name": "child2",
"parent": 1
}
}
},
"2":{
"id": 2,
"name": "parent2"
}
}
And this is what I would like to accomplish. So keep the same order but flatten the object:
{
"1": {
"id": 1,
"name": "parent",
},
"4": {
"id": 4,
"name": "child1",
"parent": 1
},
"5": {
"id": 5,
"name": "child2",
"parent": 1
},
"2": {
"id": 2,
"name": "parent2"
}
}
So far I haven't found a solution to this. I've tried a function without much success:
protected function _flattenObject($array)
{
static $flattened = [];
if(is_object($array) && count($array) > 0)
{
foreach ($array as $key => $member) {
if(!is_object($member))
{
$flattened[$key] = $member;
} else
{
$this->_flattenObject($member);
}
}
}
return $flattened;
}
The tough part for me is to keep the same order (children below its parent). And the function mentioned above also removes all objects and almost only keeps the keys with its value, so it wasn't a great success at all.
Hopefully somebody over here knows a good solution for this.
By the way, the reason I want such flatten structure is because the system I have to work with, has trouble handling multidimensional arrays and objects. And I still want to display an hierarchy, which is possible with the flatten structure I described, because the objects actually contain a "level" key as well so I can give them some padding based on the "level" while still showing up below their parent.
EDIT:
The JSON didn't seem to be valid, so I modified it a bit.
The main problem seems to be that you are not doing anything with the returned results of your recursive function. Unless using static inside a method does some magic that I don't know of...
So this section:
if(!is_object($member))
{
$flattened[$key] = $member;
} else
{
// What happens with the returned value?
$this->_flattenObject($member);
}
Should probably be more like this:
if(!is_object($member))
{
$flattened[$key] = $member;
} else
{
// Add the returned array to the array you already have
$flattened += $this->_flattenObject($member);
}
Here is code that works. It adds a field "level" to your objects, to represent how many levels deep in the original hierarchy they were.
<?php
$obj = json_decode('[{
"id": 1,
"name": "parent",
"children": [{
"id": 4,
"name": "child1",
"parent": 1
}, {
"id": 5,
"name": "child2",
"parent": 1
}]
}, {
"id": 2,
"name": "parent2"
}]');
function _flattenRecursive($array, &$flattened, &$level)
{
foreach ($array as $key => $member) {
$insert = $member;
$children = null;
if (is_array($insert->children)) {
$children = $insert->children;
$insert->children = array();
}
$insert->level = $level;
$flattened[] = $insert;
if ($children !== null) {
$level++;
_flattenRecursive($children, $flattened, $level);
$level--;
}
}
}
function flattenObject($array)
{
$flattened = [];
$level = 0;
_flattenRecursive($array, $flattened, $level);
return $flattened;
}
$flat = flattenObject($obj);
var_dump($flat);
?>
