laravel model casts

1<?php
2
3namespace App\Models;
4
5use Illuminate\Database\Eloquent\Model;
6
7class User extends Model
8{
9    /**
10     * The attributes that should be cast.
11     *
12     * @var array
13     */
14    protected $casts = [
15        'options' => 'array',
16    ];
17}

1To define a mutator, define a setFooAttribute method on your model where Foo
2  is the "studly" cased name of the column you wish to access. So, again,
3lets define a mutator for the first_name attribute. This mutator will
4be automatically called when we attempt to set the value of the first_name
5attribute on the model:
6
7class User extends Model
8{
9    public function setFirstNameAttribute($value)
10    {
11        $this->attributes['first_name'] = strtolower($value);
12    }
13}

1Once the cast is defined, you may access
2  the options attribute and 
3  it will automatically be deserialized 
4  from JSON into a PHP array. When you set 
5  the value of the options attribute, the given 
6  array will automatically be serialized back into 
7  JSON for storage:
8
9
10use App\Models\User;
11
12$user = User::find(1);
13
14$options = $user->options;
15
16$options['key'] = 'value';
17
18$user->options = $options;
19
20$user->save();
