我已经定义了不使用时间戳,但是laravel仍然强制使用时间戳...我使用的是laravel 5.6。
当我访问页面时,例如-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');
}
}
视频评论控制器
public function index(Video $video) {
return response()->json($video->comments()->with('member')->latest()->get());
}

按热度按时间ax6ht2ek1#
最新和最旧的方法允许您轻松地按日期对结果进行排序。默认情况下,结果将按
created_at
列排序。v2g6jxz62#
如果在查询中使用latest(),则必须在db表read more.中添加created_at

当您没有
created_at
列时,可以轻松地使用orderBy
和first()
来代替latest()
。
