Das Routenmuster kann nicht mehr als einmal den variablen Namen referenzieren. Laravel
When you define a route as a resource then Laravel seems to create all the
routes necessary for your resource: GET, POST, PATCH, DELETE.
So you would just need to define
Route::resource('taxonomy','TaxonomyController');
or
Route::resource('taxonomy.post','TaxonomyPostController');
