Laravel: Add [field] to fillable property to allow mass assignment

The error

Error

Add [title] to fillable property to allow mass assignment on [App\Models\Post].

Why it happens

Model::create() and fill() only accept attributes listed in the model's $fillable array. This protects you from users setting fields like is_admin through a form.

How to fix it

  1. Add the field to $fillable in the model.
  2. Only list fields users may set; pass validated data, e.g. Post::create($request->validated()).
class Post extends Model
{
    protected $fillable = ['title', 'slug', 'body'];
}
