找不到sqlstate 42s22列1054“字段列表”中的未知列

Question

朋友，收到错误消息sqlstate 42s22 column activity_post_comments not found 1054 unknown column in 'field list'

但是此列名称存在于我的数据库中。

我已经检查了我的数据库，并且检查了拼写错误，但是我仍然收到此错误

public function storecomments(Request $request, $id)
{
    // Create Comment
    $activity_post = new ActivityPost;
    $activity_post->activity_post_comments = $request->input('activity_post_comments');
    $activity_post->activity_post_id = $id;
    $activity_post->user_id = auth()->user()->id;
    $activity_post->save();

    return redirect()->back()->with('success', 'Comment Added');
}

不确定为什么会收到此错误，所以我无法将这些值保存在数据库中

型号：

class ActivityPostComment extends Model
{
	use SoftDeletes;

    // Table Name
    protected $table = 'activity_post_comments';
    // Primary Key
    public $primaryKey = 'id';
    // Timestamps
    public $timestamps = true;

    /**
     * The attributes that should be mutated to dates.
     *
     * @var array
     */
    protected $dates = ['deleted_at'];

    public function post(){
        return $this->belongsTo('App\ActivityPost');
    }
}
