Your model is not at fault for producing the "maximum function nesting level of '100' reached" error. It's XDebug's configuration; increase your xdebug.max_nesting_level.

The following is from a 2015 post by @sitesense on laracasts.com:

This is not a bug in Laravel, Symfony or anything else. It only occurs when XDebug is installed.

It happens simply because 100 or more functions are called recursively. This is not a high figure as such and later versions of XDebug (>= 2.3.0) have raised this limit to 256. See here:

http://bugs.xdebug.org/bug_view_page.php?bug_id=00001100

EDIT: In fact the latest Homestead provisioning script already sets the limit to 250. See line 122 here:

https://github.com/laravel/settler/blob/master/scripts/provision.sh#L122

So the addition of xdebug.max_nesting_level = 250 to php.ini should do it.
