I have this route defined:

Route::get('/categories/{category}/{country}/{state?}/{county?}/{city?}', ['App\Http\Controllers\LocationController', 'show'])->withScopedBindings();

public function show(Category $category, Country $country, State $state = null, County $county = null, City $city = null) {
   echo 'ok';
}

It’s fine, automatically checks for relationships, works with 1, 2 or 3 of optional parameters. But… I want to extend it so it that the COUNTY is not always mandatory. Cause there are some cities that have direct relationship to state without county_id in the middle. Cities table has county_id and also state_id and always only one of them is present. If I add:

Route::get('/categories/{category}/{country}/{state?}/{city?}', ['App\Http\Controllers\LocationController', 'show'])->withScopedBindings();

Only one of the routes are working.

How can I fix this? Thanks.
