在缓存中包装 laravel 查询::remember

Question

我想将我的 laravel 查询包装在 cache::remember() 方法中，这不是什么大问题。我的问题是我的查询首先从控制器调用该函数，并且该文件中有一个文件 transaction.php。我正在调用这个函数，在它之后，我在这个函数返回查询的最后放置了一些 where() 条件。最终查询给出结果，我将其传递到 Yajra 数据表中。 简而言之，我的查询不在同一个文件上，因此我可以包装在 cache::remember() 函数中。

我如何包装我的查询，它放在两个文件中，controller 和 transaction.php。希望你能理解。

这是控制器内部的一个函数：

你可以看到附加的图片我的目标是如何在这个查询上使用 cache::remember。

Controller file

transactions.php file

Answer 1

扩展 transactionUtil 文件以执行整个查询。您还需要收集用于构造查询的所有部分，以形成它们的唯一组合的唯一键。例如，这可能是事务实用程序中的一个函数：

function getFullResult($business_id, $sale_type) {
        $queryParameters = array_merge(compact('business_id, sale_type'), request()->all()); // You can filter these into the ones that are used for the query only
        $cacheDurationSeconds = 3600;
        return Cache::remember('getFullResult'.md5(json_encode($queryParameters)), $cacheDurationSeconds, function () use ($business_id, $sale_type) {      
             $sells = $this->getListSells($business_id, $sale_type, request()->customer_id);
            if (request()->only_subscriptions) {
                $sells->where(function ($q) {
                    $q->whereNotNull('transactions.recur_parent_id')
                    ->orWhere('transactions.is_recurring', 1);
                 });
            }

            if (!empty(request()->list_for) && request()->list_for == 'service_staff_report') {
                $sells->whereNotNull('transactions.res_waiter_id');
            }
            // ....
             return $sells->where('transactions.is_suspend', 1)
                        ->with($with)
                        ->addSelect('transactions.is_suspend', 'transactions.res_table_id', 'transactions.res_waiter_id', 'transactions.additional_notes')
                        ->get();   
       });

}

这里我使用md5 生成唯一密钥，因为它速度快，并且对于这个特定用例而言，哈希冲突的可能性很低。

但是，鉴于查询的复杂性，您需要质疑在请求中获得多个相同参数的可能性，因为如果您不这样做，那么缓存将无济于事。
