Concurrency checking data in request form

[MostafaRabia]

HI

What about you need to checking if data is exist with your additional where and make sure that there are no race condition?
like:
'item' => [ Rule::exists('items', 'id')->where('is_available', true) ]
and you are using lockForUpdate in your code for making sure that there is no one showing this item until it release
If there are 2 choosed the same item, they are both will pass the request form, and one of them will be stuck waiting the another to be finished

So, what about using lockForUpdate in the Rule itself? so he won't pass the request form and showing that the item is not available anymore

Thanks
