How to make cnc on laravel?

Question

Laravel

Now the pages go like this: /watch/1
You need to add a slug to the page address, i.e. something like this: /watch/1-slug
And there are a few questions:
Do I need to do (for SEO?) what would when going to /watch/1, it threw a 301 redirect to /watch/1-slug?
Do I need to do (for SEO?) so that when I visit /watch/1-random-string, it will throw a 301 redirect to /watch/1-slug?
What is the right way to do this in laravel itself?
Now I have done this:

Route::get('/watch/{id}-{slug}', '[email protected]');

public function get($id, $slug)
{
        $watch = Watch::findOrFail($id);
        if ($slug != $watch->slug)
            return redirect('/watch/'.$watch->id.'-'.$watch->slug, 301);
}

But there are two problems:
When accessing /watch/1, it throws a 404 error
When accessing /watch/1- it throws a 404 error
How to do it right?

Answer 1

From an SEO point of view, the redirect is done so that there are no duplicates. If you don't use "/watch/1" and don't return a duplicate of the "/watch/1-slug" page, but 404, then everything is OK and nothing else is needed.
It's probably best to uniqueize the slug

Answer 2

1. what prevents the entire line from being made as a slug and parsing or giving it to the model in the controller so that it decides what to do with such a slug?
2. yes, it's better to redirect to the desired URL, i.e. if you know id then ask model current url is equal or not
