如何在雄辩模型中动态设置表名 [英] How to dynamically set table name in Eloquent Model

问题描述

我是Laravel的新手.我正在尝试使用Eloquent Model访问数据库中的数据.

I am new to Laravel. I am trying to use Eloquent Model to access data in DB.

我有一些共享相似之处的表，例如表名.

I have tables that shares similarities such as table name.

因此，我想使用一种模型来访问数据库中的多个表，如下所示，但没有运气.

So I want to use one Model to access several tables in DB like below but without luck.

有没有办法动态设置表名?

Is there any way to set table name dynamically?

任何建议都将不胜感激.预先谢谢你.

Any suggestion or advice would be appreciated. Thank you in advance.

型号:

class ProductLog extends Model
{

    public $timestamps = false;

    public function __construct($type = null) {

        parent::__construct();

        $this->setTable($type);
    }
}

控制器:

public function index($type, $id) {

    $productLog = new ProductLog($type);

    $contents = $productLog::all();

    return response($contents, 200);
}

解决方案对于遭受相同问题困扰的人:

我可以通过@Mahdi Younesi建议的方式更改表名.

I was able to change table name by the way @Mahdi Younesi suggested.

然后我可以通过以下方式添加条件

And I was able to add where conditions by like below

$productLog = new ProductLog;
$productLog->setTable('LogEmail');

$logInstance = $productLog->where('origin_id', $carrier_id)
                          ->where('origin_type', 2);

推荐答案

以下特征允许在水合期间传递表名.

The following trait allows for passing on the table name during hydration.

trait BindsDynamically
{
    protected $connection = null;
    protected $table = null;

    public function bind(string $connection, string $table)
    {
       $this->setConnection($connection);
       $this->setTable($table);
    }

    public function newInstance($attributes = [], $exists = false)
    {
       // Overridden in order to allow for late table binding.

       $model = parent::newInstance($attributes, $exists);
       $model->setTable($this->table);

       return $model;
    }

}

这里是使用方法:

class ProductLog extends Model
{
   use BindsDynamically;
}

像这样调用实例上的方法:

Call the method on instance like this:

public function index() 
{
   $productLog = new ProductLog;

   $productLog->setTable('anotherTableName');

   $productLog->get(); // select * from anotherTableName


   $productLog->myTestProp = 'test';
   $productLog->save(); // now saves into anotherTableName
}
