php - Laravel error: Call to a member function format() on string

Question

I am using Laravel 5.3.

There is a field expired_at in table articles：

public function store(Request $request)
{
    $data=[
         'expired_at'=>Carbon::now()->addDays(30)->endOfDay()
    ];
    $article=Article::create(array_merge($request->all(),$data));

    return redirect('/artilces');
}

view:

{{$article->expired_at->format('Y-m-d')}}

error:

Call to a member function format() on string (View: D:wnmpwwwlaravel-5-3-dev esourcesviewsartilesindex.blade.php)

Why is it？

Answer 1

In your Article class add following property:

/**
 * The attributes that should be mutated to dates.
 *
 * @var array
 */
protected $dates = ['expired_at'];
