Laravel数据库通知在数据库

所以我想在数据库中保存通知。但是,一旦将带有值的模型的对象传递给Notification类,数据就不会保留在其中,并且我会收到以下消息

  

Illuminate \ Database \ QueryException(HY000)       SQLSTATE [HY000]:常规错误:1364字段'post_title'没有默认值(SQL:插入postsupdated_at,   created_at)值(2017-09-21 15:58:01,2017-09-21 15:58:01))

现在我有 Post_title和Post_description ,但这里没有显示。

以下是我的通知类,奇怪的是,如果我转储发布对象

,我会在构造函数中获取所有与帖子相关的信息
<?php

namespace App\Notifications;

use Carbon\Carbon;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notifiable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;

class PostCreated extends Notification
{
    use Queueable,Notifiable;

    protected $post;
    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct($post)
    {
        $this->post = $post;
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['database'];
    }
    /**
     * Get the array representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            'post_id' => $this->post->id,
            'user_id' => $this->post->user_id,
        ];
    }
}

如果需要更多信息,请与我们联系。 编辑:发布模型

根据你的需要,有几个解决方案。

如果您总是想要post_titlepost_description的值,那么您需要添加一些验证并检查值是否已传递到您的控制器以在db中设置并且您的模型将填补这些价值。

请参阅https://laravel.com/docs/5.5/validation

但是,如果标题和说明始终未设置,那么这可能是您的数据库,而不是您的代码。如果这些字段有时可能未被使用,那么您希望将每个字段的默认值设置为&#39;&#39;&#39;&#39;或者是NULL。

有点像

ALTER TABLE <table> ALTER j SET DEFAULT '';

<强>最后

Tbh我认为你不需要那个构造函数,但我可能错了。

答案 1 :(得分:0)

post_title的值设为空白或更新架构,将默认值设置为空白->default("");

如果未设置为默认值,则始终需要列post_title任何值。

还要确保在模型中添加了post_title

protected $fillable = ['post_title',....];// all columns
