whats the difference between fillable and guard in laravel?

Question

I am newbie in Laravel and want to understand this with example. what are main difference between fillable and guard in laravel? How those are differentiated? Please share one basic example.

Answer 1

Example 1

protected $fillable = ['name', 'email'];

It means we want to insert only name,and email colmn values

Example 2

protected $guarded = ['name', 'email'];

It means we want to ignore only name & email we don't want to insert values of name & email colmn

Example 3

protected $guarded = [];

We want to insert all columns values

Answer 2

First as a newbie refer the documentation on laravel site. I suppose you are asking about fillable vs guarded.

Fillable is ready for mass assignments i.e. you can use fill() with array of value sets instead of one-one assignments. Below name and email are fillable.

 class User extends Eloquent{
  public $timestamps = false;
  protected $fillable = ['name', 'email'];
}  

....
    $user = User::create($request->all);

Guarded is just opposite of fillable.

keep in mind there is one more "hidden" which means its not available for json parsing. so if you use

 return User::all();

the returned json will skip all fields mentioned in hidden. Also the hidden doesn't explicitly means guarded.

In Laravel, $fillable attribute is used to specify those fields which are to be mass assignable. $guarded attribute is used to specify those fields which are to be made non mass assignable.

$fillable serves as a "white list" of attributes that should be mass assignable and $guarded acts just the opposite of it as a "black list" of attributes that should not be mass assignable.

If we want to block all the fields from being mass-assigned, we can use:

protected $guarded = ['*'];

If we want to make all the fields mass assignable, we can use:

protected $guarded [];

If we want to make a particular field mass assignable, we can use:

protected $fillable = ['fieldName'];

Lastly, if we want to block a particular field from being mass assignable, we can use:

protected $guarded = ['fieldName'];
