Laravel：Carbon.php第425行中的InvalidArgumentException：数据丢失

Question

When I run the system, there is exist error like this :

InvalidArgumentException in Carbon.php line 425: Data missing

    in Carbon.php line 425
    at Carbon::createFromFormat('Y-m-d H:i:s', '10-12-2016') in Model.php line 2990
    at Model->asDateTime('10-12-2016') in Model.php line 2944
    at Model->fromDateTime('10-12-2016') in Model.php line 2872
    at Model->setAttribute('tglkop', '10-12-2016') in Model.php line 442

And my model is like this :

<?php

namespace App\Models;

use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class P3 extends Model
{
    use SoftDeletes;

    public $table = 'p3_s';

    protected $dateFormat = 'Y-m-d';

    protected $dates = ['deleted_at', 'tglkop', 'tglp3'];

    public $fillable = [
        'id_pagu',
        'id_p3',
        'kdbulan',
        'thang',
        'nokop',
        'tglkop',
        'tglp3'
    ];

    protected $casts = [
        'id_pagu' => 'string',
        'id_p3' => 'string',          
        'kdbulan' => 'string',
        'thang' => 'string',
        'nokop' => 'string'
    ];

    public static $rules = [
        'id_pagu' => 'required',
        'id_p3' => 'required',
        'kdbulan' => 'required',
        'thang' => 'required',
        'nokop' => 'required',
        'tglkop' => 'required',
        'tglp3' => 'required',
    ];


}

My table is like this :

id, int(10)
id_pagu, varchar(18)
id_p3, varchar(18)
kdbulan, varchar(2)
thang, varchar(4)
nokop, varchar(10)
tglkop, date
tglp3, date
created_at, timestamp
updated_at, timestamp
deleted_at, timestamp

I read some tutorial in stackoverflow and laravel docs, but I'm still confused to implement it

Is there any solution to solve my problem?

Answer 1

Just remove 'tglkop', 'tglp3' from your $casts array, and add this to '$dates' array. These properties will be automatically converted to Carbon instances

UPDATE

I guess that your db columns tglkop and tglp3 have DATE type instead of DATETIME.

This error

Carbon::createFromFormat('Y-m-d H:i:s', '10-12-2016') in blah blah blah

says that Carbon expects date with format Y-m-d H:i:s but you gives date in format d-m-Y (10-12-2016)

Solution 1: change type of these columns to DATETIME

Solution 2: add that in your model

protected $dateFormat = 'Y-m-d'; // this is expected format for `MySQL` `DATE` type field

UPDATE 2

I think you tries to create row in database. What data are you trying to pass into? I think tglkop and tglp3 fields in your input have wrong format.
