Question

我有默认的laravel通知数据字段和默认的通知表只尝试根据用户的通知数据值为用户选择一些通知，我已经在用户模型中创建了此功能

public function notifications_data($col)
{
$notifications = $this->notifications()->where('data' , function ($q) use ($col){
            $q->where('appointment_id','0'); // query data as table
        })->get();

return ($notifications);

}

我已在通知表col数据中保存了值{“ type”：“ Appointment”，“ appointment_id”：“ 0”，“ date”：null，“ updated_by”：“”，“ status”：“ 0”}

如何获取状态为0或约会ID = 0的所有通知

Answer 1

也许可行：

sc %>% spark_session() %>% invoke("catalog") %>% invoke("dropTempView", "iris")

Answer 2

使用Laravel的查询生成器：

public function notifications_data()
{
    $notifications = DB::table('notifications')  //Specify the table you want to query
        ->where('status',0)    //Where status = 0
        ->orWhere('appointment_id',0)   //or appointment_id = 0
        ->get();

    return $notifications;
}

Answer 3

您还可以使用：

public function notifications_data($col)
{
  $notifications = $this->notifications()
    ->where('data->appointment_id', 0)
    ->orWhere('data->status', 0)
    ->get();

  return ($notifications);
}

laravel通过数据字段为用户选择通知
