FindOrFail laravel 5 function for specific feed

Question

This is my code:

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

Using this query, laraveltry to find the identifier specified in the table.

I do not have an identifier, for the primary key I have a mail column.

So, how to set the function to search the value in the mail column, and not to search from the id column?

Thank,

You can create the behavior you are looking for with the following:

Geo_Postal_us::where('postal', $postal)->firstOrFail();
