I am finding a way to somewhat fire an event after the Eloquent has finished creating.
Here's my code in Branch model:
class Branch extends Model
{
//some code here
public static function boot() {
parent::boot();
self::created(function (HistoryLog $model) {
$model->tag = 'Created';
$model->description = 'This branch was created by '. ucwords(auth()->user()->name());
$model->save();
});
}
}
What I'm trying to do is, I want to create a history_log after branch was created.
But this code returns an error:
Symfony\Component\Debug\Exception\FatalThrowableError : Argument 1 passed to
App\Vehicle::App{closure}() must be an instance of App\HistoryLog, instance of
App\Vehicle given, called in D:\document\My Documents\optodph\vendor\laravel\fr
amework\src\Illuminate\Events\Dispatcher.php on line 347
Can someone point out to me what's wrong with that code? And what's the right way to achieve this?
Laravel way to do this.
Create an Observer:
php artisan make:observer BranchObserver --model=Branch
Add your logic to the Observer:
<?php
namespace App\Observers;
use App\Branch;
class BranchObserver
{
/**
* Handle the Branch "created" event.
*
* #param \App\Branch $branch
* #return void
*/
public function created(Branch $branch)
{
// Add your logic here
}
}
Register it in AppServiceProvider:
<?php
namespace App\Providers;
use App\Branch;
use App\Observers\BranchObserver;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
Branch::observe(BranchObserver::class);
}
}
$model is a new record created. Is an instance of App\Vehicle not a App\HistoryLog.
Working code might look like this:
class Vehicle extends Model
{
//some code here
public static function boot() {
parent::boot();
self::created(function ($model) {
App\HistoryLog::create([...]);
});
}
}
You can also achieve this with Eloquent Observers https://laravel.com/docs/5.8/eloquent#observers

I try to import a file with Laravel Command. The import works well. After the import, Laravel triggers an event. This works also well.
With a listener, I catch the event. It works well when I do as example dd('it works')!
<?php
namespace App\Listeners;
use App\EventsNew\Notifiables\ConsignmentCreatedViaApi;
class ConsignmentCreatedListener
{
public function __construct()
{
}
public function handle($event)
{
dd('it works');
}
}
But if I try to save some values into the db, it doesn't work, neighter it returns an error:
<?php
namespace App\Listeners;
use App\Models\Settlement;
class ConsignmentCreatedListener
{
/**
* Create the event listener.
*
* #return void
*/
public function __construct()
{
}
/**
* Handle the event.
*
* #param object $event
* #return void
*/
public function handle( $event)
{
Settlement::create([
'consignment_id'=> 1
]);
}
}
I tried to execute Settlement::create in the console command and it works.
Isn't it possible to insert something into the db after an avent? Or is there another way to do it?
I have a very simple example to show the problem:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
class VendorCounts extends Command
{
/**
* The name and signature of the console command.
*
* #var string
*/
protected $signature = 'vendor:counts
{year : The year of vendor counts}';
/**
* The console command description.
*
* #var string
*/
protected $description = 'Runs vendor counts';
/**
* Create a new command instance.
*
* #return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* #return mixed
*/
public function handle()
{
$this->info('Starting Vendor Counts');
}
}
<?php
namespace Tests\Feature\Console\Vendor;
use Tests\TestCase;
class VendorCountsTest extends TestCase {
public function testVendorCounts()
{
$this->artisan('vendor:counts', ['year' => 2019])
->expectsOutput('Starting Vendor Counts')
->assertExitCode(0);
}
}
I get the following error:
1) Tests\Feature\Console\Vendor\VendorCountsTest::testVendorCounts
Error: Call to a member function expectsOutput() on integer
/Users/albertski/Sites/vrs/tests/Feature/Console/Vendor/VendorCountsTest.php:12
I know the command definitely runs because if I put a dump statement in it shows the debug output.
I am using Laravel 6.3. Is there a different way to test this?
The problem I was using was that TestCase was using Laravel\BrowserKitTesting\TestCase as BaseTestCase. I ended up creating another Base just for console commands.
<?php
namespace Tests;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;
abstract class ConsoleTestCase extends BaseTestCase
{
use CreatesApplication;
}
Can you add this to your VendorCountsTest class:
public $mockConsoleOutput = true;
This is set by a trait but just making sure something hasn't changed the value. When $mockConsoleOutput is false it will directly run the artisan commmand. When it is true it will wrap it in a PendingCommand object that has those methods you are trying to call.
I had an issue where the use of expectedOutput() on my Artisan class would fail all the time, which turned out to be because I had used exit() and/or die() in a method, which really did not work well with phpunit test methods.
So if you want to stop processing the "script" at some point, just use an empty return and not exit() or die() if you want to utilize the built-in ->artisan() testing in Laravel.
Working example:
<?php
// app/Console/Commands/FooCommand.php
public function handle()
{
$file = $this->argument('file');
if (! file_exists($file)) {
$this->line('Error! File does not exist!');
return;
}
}
// tests/Feature/FooCommandTest.php
public function testFoo() {
$this->artisan('foo', ['file' => 'foo.txt'])->expectsOutput('Something');
}
Non-working example:
<?php
// app/Console/Commands/FooCommand.php
public function handle()
{
$file = $this->argument('file');
if (! file_exists($file)) {
$this->line('Error! File does not exist!');
exit;
}
}
// tests/Feature/FooCommandTest.php
public function testFoo() {
$this->artisan('foo', ['file' => 'foo.txt'])->expectsOutput('Something');
}
i want to display the counter in my app.blade which being called in all pages like the screenshot below
I only have this function in my controller
class ReportsController extends Controller
{
public function invoiceTransaction()
{
$salespayments = Salespayments::where('type','=','check')->get();
$countUnread = Salespayments::select(DB::raw("SUM(unread) as unread"))->get();
return view('reports.invoiceTransactions')
->with('salespayments', $salespayments)
->with('countUnread', $countUnread);
}
}
And I am calling the counter in my blade by this {{$countUnread[0]->unread}}
How can I make that function be readable in my app.blade.php? thanks a lot!
In your AppServiceProvider you can share the sum result across all views by using view()->share();
Like this:
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot() {
$countUnread = Salespayments::sum('unread');
view()->share('countUnread', $countUnread);
}
Make a service provider first,
php artisan make:provider CounterServiceProvider
Then in your CounterServiceProvider file.
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Views\Composers;
class CounterServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
// here define your master layout
$this->app['view']->composer(['master'], Composers\Counter::class);
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
//
}
}
Now in your App\Views\Composers folder add Counter class.
<?php
namespace App\Views\Composers;
use Illuminate\View\View;
class Counter {
public function compose(View $view)
{
$view->with('countUnread', session('countUnread'));
}
}
Make sure you add your CounterServiceProvider in config/app.php file's providers array.
Most of my db table contain create_user_id and update_user_id
How can l update this two field automatic when l use save(), update(), insert(), createOrUpdate() and etc method.
For example, l execute this script:
$model = Model::find(1);
$model->model_f = 'update';
$model->save();
then this record's model_f updated, and update_user_id updated, too.
l know eloquent can manage update_time automatic and l have use it already. But l want to do something else when update or insert or delete
PS: l have a constant named USERID to remember current user's id
You could make use of Observers.
You can hook to the following events on your Model:
retrieved
creating
created
updating
updated
saving
saved
deleting
deleted
restoring
restored
Let me give you an example where we are trying to hook into the events emitted by the App/User model. You can change this to match your particular Model later on.
To create an observer, run the following command:
php artisan make:observer UserObserver --model=User
Then you can hook to specific events in your observer.
<?php
namespace App\Observers;
use App\User;
class UserObserver
{
/**
* Handle the User "saved" event.
*
* #param \App\User $user
* #return void
*/
public function saved(User $user)
{
//
}
/**
* Handle the User "created" event.
*
* #param \App\User $user
* #return void
*/
public function created(User $user)
{
//
}
/**
* Handle the User "updated" event.
*
* #param \App\User $user
* #return void
*/
public function updated(User $user)
{
//
}
}
Since, in your particular case, you want to hook into these 3 events, you can define the events above and perform additional operations to your model when those events are called.
Don't forget to register this observer in your AppServiceProvider.
<?php
namespace App\Providers;
use App\User;
use App\Observers\UserObserver;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
User::observe(UserObserver::class);
}
/**
* Register the service provider.
*
* #return void
*/
public function register()
{
//
}
}
There is pretty simple way to automatically update the create_user_id and update_user_id
Step1:
Open you app folder and create the new file named as UserStampsTrait.php
Step:2
and paste the following code
<?php
namespace App;
use Illuminate\Support\Facades\Auth;
trait UserStampsTrait
{
public static function boot()
{
parent::boot();
// first we tell the model what to do on a creating event
static::creating(function($modelName='')
{
$createdByColumnName = 'create_user_id ';
$modelName->$createdByColumnName = Auth::id();
});
// // then we tell the model what to do on an updating event
static::updating(function($modelName='')
{
$updatedByColumnName = 'update_user_id';
$modelName->$updatedByColumnName = Auth::id();
});
}
}
Thats it
Step:3
Open you model which needs to updated the corresponding models automatically
for Example it may be Post
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use App\UserStampsTrait;
class Post extends Model
{
use UserStampsTrait;
}
Thats it
Im working on a Laravel 5 app and im trying to set up a ComposerServiceProvider to pass data to a couple of views (im trying now to add it to the layout/app.blade.php).
I did this following the documentation but the data im trying to add is still undefined..
In my config/app.php I added to the providers:
App\Providers\ComposerServiceProvider::class,
On ComposerServiceProvider.php
boot method:
View::composer(['layouts.app'], 'App\ViewComposers\LayoutAppComposer');
On the new created LayoutAppComposer.php
compose(View $view) method:
$metaTitle = 'MetaTitle';
$view->with('metaTitle', $metaTitle)
But When i access the url I still get:
Undefined variable: metaTitle (View: .../resources/views/layouts/app.blade.php)
Am I missing something here??
ServiceProvider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\View;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
View::composer(['layouts.app'], 'App\ViewComposers\LayoutAppComposer');
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
}
}
LayoutAppComposer
<?php
namespace App\ViewComposers;
use Illuminate\Support\Facades\Session;
use Illuminate\View\View;
class LayoutAppComposer {
protected $metaTitle;
public function __construct($metaTitle)
{
$this->metaTitle = $metaTitle;
}
/**
* Bind data to the view.
*
* #param View $view
* #return void
*/
public function compose(View $view) {
$this->metaTitle = 'MetaTitle';
$view->with('metaTitle', $this->metaTitle);
}
}
Try changing:
$metaTitle = 'MetaTitle';
$view->with('metaTitle', $metaTitle)
to
$this->metaTitle = 'metaTitle';
$view->with('metaTitle', $this->metaTitle)
setup $this->metaTitle as a protected class member and assign it in the composer constructor. it may be that $metaTitle is getting garbage collected before you use it since this being resolved at the service provider level.
Since you're registering the composer with your app layout, instead you may need to use the wildcard character in place of app.layout like such:
View::composer('*', function ($view) {
//
});
To resolve $metaTile for the View Composer, try binding in your AppServiceProvider:
$this->app->bind('metaTitle', 'the string i want displayed across all views');
