提交表单

Question

我在Laravel中创建了一个费用表单并尝试提交它以便将数据插入到数据库中，但在提交后显示此错误：

屏幕截图显示错误

  C:\xampp\htdocs\Tailor\core\vendor\nesbot\carbon\src\Carbon\Carbon.php

    public static function createFromFormat($format, $time, $tz = null)
    {
        if ($tz !== null) {
            $dt = parent::createFromFormat($format, $time, static::safeCreateDateTimeZone($tz));
        } else {
            $dt = parent::createFromFormat($format, $time);
        }

        static::setLastErrors($lastErrors = parent::getLastErrors());

        if ($dt instanceof DateTime) {
            return static::instance($dt);
        }

        throw new InvalidArgumentException(implode(PHP_EOL, $lastErrors['errors']));
    }

    /**

    private static function setLastErrors(array $lastErrors)
    {
        static::$lastErrors = $lastErrors;
    }

    /**

    public static function getLastErrors()
    {
        return static::$lastErrors;

"Trailing data"

我已经尝试了所有可能的方式，我知道我甚至可以通过网络搜索仍然无法找到解决此问题的方法。

过去几个小时我一直在这里。

这是create.blade

费用模型

<?php

use Illuminate\Database\Eloquent\Model;
use Carbon\Carbon;

/**

Answer 1

我不知道为什么，但是有时html表单会以...example 2020-01-01T10:10:10...结尾的秒数返回数据，有时不是example 2020-01-01T10:10。

为解决此问题，我制作了substr($date,0,16).":00"，因此避免了Carbon所需的格式大小溢出。

Answer 2

就我而言，我通过将以下方法添加到我的（基础）模型中来修复 Carbon 错误。

public function getDateFormat()
{
     return 'Y-m-d H:i:s.u';
}

如果你在 Postgres 中使用 TIME WITH TIMEZONE 那么格式应该是：

Y-m-d H:i:s.uO
