我讨厌成为回答自己问题的人，但我讨厌成为不分享更有效的方法的人。
我最终创建了一个在数据级别执行连接和检查的视图。这使它成为一个简单的join 和ifnull，然后更改我的模型以使用该表而不是基础。这非常适合读取和查询，但显然不适用于 CRUD 操作。
由于此视图不可更新，我最终在准备进行任何写入时利用模型事件系统将模型切换到基表，然后在完成后返回。我选择了观察者模式，因为它让一切都保持整洁。
观察者：

class PersistToObserver
{
protected function useReadTable(IPersistTo $model)
{
$model->setTable($model->getReadTable());
}

{
$model->setTable($model->getWriteTable());

IPersistTo 合约/接口
<?php
namespace App\Models\Contracts;
interface IPersistTo
{
/**
* @return string - the name of the table to read from (should be the same as the default $table)
*/
public function getReadTable();
/**
* @return string - the name of the table to write to
*/
public function getWriteTable();
/**
* Set the table associated with the model. Fulfilled by Model.
*
* @param string $table
* @return $this
*/
public function setTable($table);
}
我的模型中的设置（被截断为相关信息）
class Game extends Model implements IPersistTo {
protected $table = 'game_with_album_fallback';
/**
* @return string - the name of the table to read from (should be the same as the default $table)
*/
public function getReadTable()
{
return 'game_with_album_fallback';
}
/**
* @return string - the name of the table to write to
*/
public function getWriteTable()
{
return 'games';
}
}
最后将所有这些连接在一起，将以下行添加到 AppServiceProvider 的启动方法中：
Game::Observe(PersistToObserver::class);
