Why is Slug not working?

Question

Laravel

Err: Sorry, the page you are looking for could not be found.
Route: /posts/hello-world
What could be wrong?
web.php How to fix? :(
Route::resource('/posts', 'PostController');

Answer 1

If the database checks id instead of slug, then you need to specify in the model the key by which the search in the database should be performed. getRouteKeyName()

Answer 2

You don't need packages. Write this functionality yourself. Laravel has everything for this - route model binding and str_slug ().
Then it will immediately become clear what is wrong.
