findOrFail laravel 5功能针对特定领域

This is my code:

这是我的代码：

$get_all = Geo_Postal_us::findOrFail($postal);

With this query,laravel try to find ID filed in table.

通过此查询，laravel尝试在表中查找ID。

I don't have id filed, for primary key i have postal column.

我没有id提交，对于主键我有邮政专栏。

So, how to set function to find value in postal column, not to search from id column ?

那么，如何设置函数在邮政列中查找值，而不是从id列中搜索？

Thanks,

谢谢，
