php - 找不到 laravel 列 : 1054 Unknown column 'created_at' in 'order clause'

Question

我已定义不使用时间戳，但 laravel 仍然强制使用时间戳...我使用的是 laravel 5.6。

例如，当我访问页面时 - http://mypage/api/videos/21/comments 我收到一个错误 - “SQLSTATE[42S22]:未找到列:1054 ‘order 子句’中的未知列‘created_at’(SQL:从 videos_comments 中选择 *，其中 videos_comments。 video_id = ▶"

app/Providers/VideoComment.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class VideoComment extends Model
{
protected $table = 'videos_comments';
public $timestamps = false;
protected $fillable = [
  'text', 'userid', 'date'
];
public function videos() {
  return $this->belongsTo('App\Video', 'id', 'video_id');
}
public function member() {
  return $this->belongsTo('App\Member', 'userid', 'member_id');
}
}

app/Providers/Video.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Cviebrock\EloquentSluggable\Sluggable;

class Video extends Model
{
protected $table = 'videos';
public $timestamps = false;
use Sluggable;

public function sluggable() {
  return [
      'slug' => [
          'source' => 'title'
      ]
    ];
}
public function comments() {
  return $this->hasMany('App\VideoComment', 'video_id', 'id');
}
public function member() {
  return $this->belongsTo('App\Member', 'userid', 'member_id');
}
}

VideoCommentController.php 函数

   public function index(Video $video) {
    return response()->json($video->comments()->with('member')->latest()->get());
   }

如果您在查询中使用 latest()，那么您必须在数据库表中添加 created_at，read more.
