06. Deleting Chirps

Sometimes no amount of editing can fix a message, so let's give our users the ability to delete their Chirps.

Hopefully you're starting to get the hang of things now. We think you'll be impressed how quickly we can add this feature.

Routing

We'll start again by updating our routes to enable the chirps.destroy route:

routes/web.php
<?php
 ...
use App\Http\Controllers\ChirpController;
use Illuminate\Support\Facades\Route;
 
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
 
Route::get('/', function () {
return view('welcome');
});
 
Route::get('/dashboard', function () {
return view('dashboard');
})->middleware(['auth'])->name('dashboard');
 
Route::resource('chirps', ChirpController::class)
->only(['index', 'store', 'edit', 'update'])
->only(['index', 'store', 'edit', 'update', 'destroy'])
->middleware(['auth', 'verified']);
 ...
require __DIR__.'/auth.php';
 

Our route table for this controller now looks like this:

Verb URI Action Route Name
GET /chirps index chirps.index
POST /chirps store chirps.store
GET /chirps/{chirp}/edit edit chirps.edit
PUT/PATCH /chirps/{chirp} update chirps.update
DELETE /chirps/{chirp} destroy chirps.destroy

Updating our controller

Now we can update the destroy method on our ChirpController class to perform the deletion and return to the Chirp index:

app/Http/Controllers/ChirpController.php
<?php
 ...
namespace App\Http\Controllers;
 
use App\Models\Chirp;
use Illuminate\Http\Request;
 
class ChirpController extends Controller
{
 ...
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
return view('chirps.index', [
'chirps' => Chirp::with('user')->latest()->get(),
]);
}
 
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
//
}
 
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$validated = $request->validate([
'message' => 'required|string|max:255',
]);
 
$request->user()->chirps()->create($validated);
 
return redirect(route('chirps.index'));
}
 
/**
* Display the specified resource.
*
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Http\Response
*/
public function show(Chirp $chirp)
{
//
}
 
/**
* Show the form for editing the specified resource.
*
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Http\Response
*/
public function edit(Chirp $chirp)
{
$this->authorize('update', $chirp);
 
return view('chirps.edit', [
'chirp' => $chirp,
]);
{
 
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Http\Response
*/
public function update(Request $request, Chirp $chirp)
{
$this->authorize('update', $chirp);
 
$validated = $request->validate([
'message' => 'required|string|max:255',
]);
 
$chirp->update($validated);
 
return redirect(route('chirps.index'));
}
 
/**
* Remove the specified resource from storage.
*
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Http\Response
*/
public function destroy(Chirp $chirp)
{
//
$this->authorize('delete', $chirp);
 
$chirp->delete();
 
return redirect(route('chirps.index'));
}
}

Authorization

As with editing, we only want our Chirp authors to be able to delete their Chirps, so let's update the delete method our ChirpPolicy class:

app/Policies/ChirpPolicy.php
<?php
 ...
namespace App\Policies;
 
use App\Models\Chirp;
use App\Models\User;
use Illuminate\Auth\Access\HandlesAuthorization;
 
class ChirpPolicy
{
 ...
use HandlesAuthorization;
 
/**
* Determine whether the user can view any models.
*
* @param \App\Models\User $user
* @return \Illuminate\Auth\Access\Response|bool
*/
public function viewAny(User $user)
{
//
}
 
/**
* Determine whether the user can view the model.
*
* @param \App\Models\User $user
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Auth\Access\Response|bool
*/
public function view(User $user, Chirp $chirp)
{
//
}
 
/**
* Determine whether the user can create models.
*
* @param \App\Models\User $user
* @return \Illuminate\Auth\Access\Response|bool
*/
public function create(User $user)
{
//
}
 
/**
* Determine whether the user can update the model.
*
* @param \App\Models\User $user
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Auth\Access\Response|bool
*/
public function update(User $user, Chirp $chirp)
{
return $chirp->user()->is($user);
}
 
/**
* Determine whether the user can delete the model.
*
* @param \App\Models\User $user
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Auth\Access\Response|bool
*/
public function delete(User $user, Chirp $chirp)
{
//
return $this->update($user, $chirp);
}
 ...
/**
* Determine whether the user can restore the model.
*
* @param \App\Models\User $user
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Auth\Access\Response|bool
*/
public function restore(User $user, Chirp $chirp)
{
//
}
 
/**
* Determine whether the user can permanently delete the model.
*
* @param \App\Models\User $user
* @param \App\Models\Chirp $chirp
* @return \Illuminate\Auth\Access\Response|bool
*/
public function forceDelete(User $user, Chirp $chirp)
{
//
}
 
}

Rather than repeating the logic from the update method, we can define the same logic by calling the update method from our destroy method. Anyone that is authorized to update a Chirp will now be authorized to delete it as well.

Updating our view

Finally, we can add a delete button to the dropdown menu we created earlier in our chirps.index view:

resources/views/chirps/index.blade.php
<x-app-layout>
<div class="max-w-2xl mx-auto p-4 sm:p-6 lg:p-8">

Testing it out

If you Chirped anything you weren't happy with, try deleting it!
