Now we modify our/users route as follows: Copy the Code code as follows:Route::get (' Users ', function (){$users = User::all (); Return View::make (' users ')->with (' users ', $users);}); Let's take a look at the route. First, the all method of the User model will get all the records from the Users table. Next, we pass these records to the view through the With method. The With method accepts a key and a value, and the value can b
