Laravel collection 不包含

Question

我有一个幼虫 collection，我正试图让它显示不包含值的结果。

我知道 $data->contains(key, value)，它基本上需要与此相反。我正在尝试在 blade 模板中使用这样的代码；

    @if(!$orders->contains('order_status', 'Complete'))

和

    @if($orders->contains('order_status', 'Complete') === false)

但两者都没有达到预期效果。

有什么想法或替代方法（如果可能，想尝试保持 blade 中的逻辑）？

谢谢

Answer 1

原来这只是一个逻辑错误as discussed in chat。

@if(!$orders->contains('order_status', 'Complete'))

这是说只有在没有使用 order_status 'Complete' 而不是预期的 "show this if there are any orders that are not 'Complete'".

的订单时才显示 table

Answer 2

我会添加一些东西来避免 ! 以使其更漂亮：

@unless($orders->contains('order_status', 'Complete'))
