The casting attribute in laravel provides similar functionality to use all that call without defining any additional methods. Instead $casts attribute provides in model common database in eloquent query model. Also, you can make it manually as you want to make it with your self logic.

$casts will use for common database attributes for the whole model in the laravel, There you don't need to define and additional method for it, Once define that attribute will apply in whole class's attribute as its matching attributes in casts key.

How To Use Casts?

The $casts property should always be in an array while the key is the name of the attribute being cast the value of the column will change in a different database.

Example 1:

Simple determine casts in the model.

protected $casts = [
    'email_verified_at' => 'datetime',
    'create_at' => 'datetime:Y-m-d H:i:s',
    'updated_at' => 'datetime:Y-m-d H:i:s',
    'status' => 'boolean',
    'password' => 'encrypted',

Above exmaple to determine the status attribute as boolean,create_at and updated_at attribute date format will datetime:Y-m-d H:i:s.

Example 2:

Simple exmaple casts use in model with protected.

namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class User extends Model
     * The attributes that should be cast.
     * @var array

    protected $casts = [
        'is_admin' => 'boolean',

After defining is_admin attribute in cast, So the is_admin attribute will alwasy be cast as boolean, When you will access the is_admin attribute it will return boolean always.

$user = App\Models\User::find(1);
if ($user->is_admin) {

But sometimes you don't wise to collection data with a cast, That time using mergeCasts for that query result the casts will not apply from the model for the temporary base.

    'is_admin' => 'integer',

if ($user->is_admin == 1) {

Example 3:

Also, you can use eloquent queries too:

$user = App\Models\User::query()
    'is_admin' => 'boolean',

    // TRUE

Using able example you will just get only for that query result. Casts attribute will apply for that query only. while the protected $casts will apply in whole model.
