Laravel - transform field name with uppercase capital in json response - laravel

Question

I'm working with Laravel 6.x, I have an "Item" class like :
Schema::create('items', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('type');
$table->string('subtype');
});
In a controller, I have a route for get all items and return a json response like :
public function getItems()
{
return response()->json([
'datas' => Item::all()
]);
}
This function return this json :
{
"datas": [
{
"id": 1,
"name": "FIRE",
"type": "9",
"subtype": "5"
},
{
"id": 2,
"name": "FIRE",
"type": "9",
"subtype": "5"
}
]
}
I need to dynamically add an uppercase on the first letter of each field before returning the json response, without change the laravel field name and the migration. I need to keep the field in lowercase in Laravel.
What I need is :
{
"datas": [
{
"Id": 1,
"Name": "FIRE",
"Type": "9",
"Subtype": "5"
},
{
"Id": 1,
"Name": "FIRE",
"Type": "9",
"Subtype": "5"
}
]
}
How can I do that simply ? I have a lots of class with a lots of fields in real. Thanks !

Answer 1

You could use the Eloquent: API Resources like this:
php artisan make:resource Item
then you will get a class in the Resources folder. That's where you edit the keys
Resources/Item.php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class Item extends JsonResource
{
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
return [
'Id' => $this->id,
'Name' => $this->name,
'Type' => $this->type,
'Subtype' => $this->subtype,
];
}
}
In your controller, import the newly created resource and use it.
Controllers/ItemController.php
use App\Http\Resources\Client as ClientResource;
public function getItems()
{
return response()->json([
'datas' => ItemResource::collection(Item::all());
]);
}
There you go!

You can define an additional getter in the model for the name attribute (with a new name). So you can have both name and the new attribute that you define. Use ucfirst along with strtolower.
public function getUCFirstNameAttribute($value)
{
return ucfirst(strtolower($value));
}
OR
You can define an Items Resource. Inside the toArray method, you can use ucfirst on the name field.
return [
...
'name' => ucfirst($this->name),
...
];
Both ways you can keep the original field as is.

Simple and Generic solution :
public function toArray() {
$array = parent::toArray();
$newArray = array();
foreach($array as $name => $value){
$newArray[str_replace('_', '', ucwords($name, '_'))] = $value;
}
return $newArray;
}
Put this in a Model class, and after that just do : Item::all()->toArray()
This function transorm my_awesome_field to MyAwesomeField
