What is name () in Laravel
Named routing is a great feature of the Laravel framework. Named routes allow you to refer to routes when generating redirects or URLs, which makes your life a lot easier.
You can specify named routes by chaining the name method onto the route definition:

//
})->name(‘profile’);
This will allow you to generate a URL or redirect to this route using the nameprofile route:
$url = route(‘profile’);
$redirect = redirect()->route(‘profile’);
When naming models in Laravel, they should be in singular, with no spaces between words, and capitalized. For example: User ( AppUser or AppModelsUser , etc), ForumThread , Comment . Bad examples: Users , ForumPosts , blogpost , blog_post , Blog_posts . But of course you can just set $this->table in your model.
