Laravel - 在每个请求中更正 url 的最佳方法？

Question

what is the best way to correct the url in specific models? I have few models with a slug and the url schema is:

Route::get('/abc/{id}/{slug?}', 'AbcController@show')->name('abc.show');
Route::get('/abc/{id}/{slug?}/def-show', 'AbcDefController@show')->name('abc.def.show');
Route::get('/abc/{id}/{slug?}/def', 'AbcDefController@create')->name('abc.def.create');

On every controller I'm asking it like this:

if ($slug !== $abc->slug) {
    return redirect()->to(route([controller-function-specific], [$abc->id, $abc->slug]));
}

return view('[blade-template]', compact(['abc']))->withCanonical($abc->slug);

What is the better approach? I tried it with observers ("retrieved") but I don't need that for every function/action in the controller (eg "index" which only lists all elements and doesnt need slug) and also the route is different.

My solution works but it's redundant because I insert this specific part in a lot functions/actions. I could write it into the model but this doesn't solve the redundant calling like checkSlug('[ROUTE]').

Any ideas?

Use Explicit Route Model Binding in your RouteServiceProvider 's boot function

public function boot()
{
    parent::boot();

    Route::bind('abc', function($value) {
      return \App\Abc::where('id', $value)
                     ->where('slug', $value)->first() ?? 
                      redirect(); // Custom resolution logic here
    });
}

Note that this makes the slug required just like your if ($slug !== $abc->slug) check
