429 too many requests laravel 8

I stumbled upon the same problem today and did some debugging. When registering the /login route, Fortify applies the Illuminate\Routing\Middleware\ThrottleRequests:login middleware to it. This means, for every request to that route, the ThrottleRequests middleware will call the RateLimiter instance for that specified key. Apparently, Fortify doesn’t register a RateLimiter for the login key.

Due to the missing key in the $limiters property of the RateLimiter instance, the ThrottleRequests middleware uses its default fallback, which doesn’t handle the edge case “there SHOULD be a rate limiter for that key, but there isn’t.” really well. The $maxAttempts variable is set to 0 and will result in flaky rate limiting behaviour.

I feel like this is a bug in Fortify, because rate limiting is also happening in the \Laravel\Fortify\Actions\EnsureLoginIsNotThrottled action, which is invoked in the \Laravel\Fortify\Http\Controllers\AuthenticatedSessionController controller. I didn’t check this on a fresh Laravel installation, though, so I don’t want to jump to conclusions here.

Anyway, long story short: As a workaround, you can simply register a rate limiter for the “login” key in some of your providers, e. g. AppServiceProvider or AuthServiceProvider:

public function boot()
{
    RateLimiter::for("login", function () {
        Limit::perMinute(5);
    });
}

Edit: I just realized that the rate limiter for the “login” key is indeed provided by Fortify within the FortifyServiceProvider class. If you happen to have a problem similar to the one discussed above, make sure that you added the FortifyServiceProvider class to your providers array in the config/app.php.

use of binding in kernel laravel 8

Route Model Binding

When injecting a model ID to a route or controller action, you will often query the database to retrieve the model that corresponds to that ID. Laravel route model binding provides a convenient way to automatically inject the model instances directly into your routes. For example, instead of injecting a user’s ID, you can inject the entire User model instance that matches the given ID.

Implicit Binding

Laravel automatically resolves Eloquent models defined in routes or controller actions whose type-hinted variable names match a route segment name. For example:

use App\Models\User;
 
Route::get('/users/{user}', function (User $user) {
    return $user->email;
});

Since the $user variable is type-hinted as the App\Models\User Eloquent model and the variable name matches the {user} URI segment, Laravel will automatically inject the model instance that has an ID matching the corresponding value from the request URI. If a matching model instance is not found in the database, a 404 HTTP response will automatically be generated.

Of course, implicit binding is also possible when using controller methods. Again, note the {user} URI segment matches the $user variable in the controller which contains an App\Models\User type-hint:

use App\Http\Controllers\UserController;
use App\Models\User;
 
// Route definition...
Route::get('/users/{user}', [UserController::class, 'show']);
 
// Controller method definition...
public function show(User $user)
{
    return view('user.profile', ['user' => $user]);
}

check logged in users linux

  1. w command : Show who is logged on and what they are doing on Linux
  2. who command : Display information about Linux users who are currently logged in
  3. whoami command : Find out who you are currently logged in as on Linux
  4. id command : See user and group information for the specified USER account on Linux

How to show current logged in users in Linux

Open the terminal window and type:
w

The w command shows information about the Linux users currently on the server, and their running processes. The first line displays, in this order:

  • The current time ( 22:11:17 )
  • How long the Linux server has been running (18 days)
  • How many users are currently logged on Linux (2 users)
  • The system load averages for the past 1, 5, and 15 minutes (1.01, 1.04, 1.05)

The following info displayed for each current logged in user:

sweta    pts/10   minitx           22:11    5.00s  0.04s  0.02s vim replicant.py

Where,

  • sweta – Login name
  • pts/10 – The tty name
  • minitx – The remote host/desktop/laptop name
  • 22:11 – Login time
  • 5.00s – Idle time
  • 0.04s – JCPU (it the time used by all processes attached to the tty. It does not include past background jobs, but does include currently running background jobs.)
  • 0.02s – PCPU (it is the time used by the current process, named in the “what” field.)
  • vim replicant.py – The command line of their current process

ignore time in datetime mysql in select in laravel 8

They do the SQL DATE() work for you, and manage the differences of SQLite.

Your result can be achieved as so:

->whereDate('date', '<=', '2014-07-10')

Though the above method is convenient, as noted by Arth it is inefficient on large datasets, because the DATE() SQL function has to be applied on each record, thus discarding the possible index.

Here are some ways to make the comparison (but please read notes below):

->where('date', '<=', '2014-07-10 23:59:59')

->where('date', '<', '2014-07-11')

// '2014-07-11'
$dayAfter = (new DateTime('2014-07-10'))->modify('+1 day')->format('Y-m-d');

->where('date', '<', $dayAfter)
->whereDate('date','=','2014-07-10')

->whereDate('date', '<=', '2014-07-10')
