我想知道,创建具有固定宽度和可变数量项目的水平菜单的最佳方法是什么？

要调整菜单以使菜单条上的项目等间距,似乎唯一的方法是使用表格宽度= 100%作为菜单包装,项目作为td.所以他们会自动调整.

是否有其他解决方案(没有td),考虑到我们不知道物品的数量,而且,它可以变化？

我想用Eloquent创建产品过滤器.

我是这样开始的

$query = Product::whereHas('variants')
        ->with('variants')
        ->with('reviews')

$query = $this->addOrderConstraints($request, $query);

$products = $query->paginate(20);

哪里

private function addOrderConstraints($request, $query)
{
    $order = $request->input('sort');

    if ($order === 'new') {
        $query->orderBy('products.created_at', 'DESC');
    }

    if ($order === 'price') {
        $query->orderBy('variants.price', 'ASC');
    }

    return $query;
}

但是,这不起作用,因为Eloquent正在执行此查询(来自Laravel DebugBar的信息)

select count(*) as aggregate from `products` where exists 
(select * from `variants` where `products`.`id` = `variants`.`product_id`)

select * from `products` where exists 
(select * from `variants` where `products`.`id` = `variants`.`product_id`)

select * from `variants` where `variants`.`product_id` …

我正在尝试按照本指南http://toroid.org/ams/git-website-howto将git推送到网站.

我已经迈出了推动网站的所有步骤,但后来我收到了错误.
