How to use route model binding in Laravel

Laravel's routing model binding can automatically inject model instances into routes to avoid manual query of databases. 1. Implicit binding: When the routing parameter name such as {user} matches the User$user in the controller, Laravel automatically finds the model according to the ID and injects it. If it is not found, it will return 404. 2. Custom routing key: Rewrite the getRouteKeyName method in the model to specify that the binding is used for fields such as slug. For example, after the Post model returns 'slug', access to /posts/laravel-tutorial will automatically find the records of the corresponding slug. 3. Explicit binding: Boot method in RouteServiceProvider

Add a check box with name remember in the login form to provide the "Remember Me" option; 3. Pass the remember parameter to the Auth::attempt() method during manual authentication to enable persistent login; 4.
