First, this is my code :
/**
*
* #Route("/delete", name="team_delete_v4")
*/
public function deleteTeam(Request $request, BaseEquipe $team, $id)
{
$entityManager = $this->getDoctrine()->getManager();
$repository = $this->getDoctrine()->getRepository(BaseEquipe::class);
$equipe = $repository->find($team->getId());
$entityManager->remove($equipe);
return $this->redirectToRoute('equipe_index_v4');
}
I've a function in my controller where I try to get/find an object by his ID and delete this object. For some reason Symfony is telling me "Unable to guess how to get a Doctrine instance from the request information for parameter "team"." and I can't guess how to resolve it. Please could you help me guys ?
PS : My version is actually 3.4
Thank you very much
In your controller you get 3 parameters, the $request, the $team and an id, but how symfony know witch $team are you sending to your controller. You have to pass the id in the url:
/**
* #Route("/delete/{id}", name="team_delete_v4")
*/
public function deleteTeam(Request $request, BaseEquipe $team)
{
$entityManager = $this->getDoctrine()->getManager();
$entityManager->remove($team);
return $this->redirectToRoute('equipe_index_v4');
}
Note that the url now is /delete/{id}, when you declare an id in a controller, symfony will find the object with this id. Take a look at the docs.
So in your template, you have to pass the id of the object that you want to delete:
path("team_delete_v4", {id: team.id})
Sorry for my english, hope this help.

Thanks in advance for helpful advice. I am using Laravel Livewire for creating components and Jetstrap for authentication for those routes that require it.
At the moment I only have one route set up for testing authentication, yet after I have logged in to view that route, I get the following error:
Too few arguments to function Livewire\LivewireManager::mount(), 0 passed in /var/www/mvp/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php on line 261 and at least 1 expected
This seems to be originating from the LivewireManager class, inside the getInstance() function:
public function getInstance($component, $id)
{
$componentClass = $this->getClass($component);
throw_unless(class_exists($componentClass), new ComponentNotFoundException(
"Component [{$component}] class not found: [{$componentClass}]"
));
return new $componentClass($id);
}
It seems to be expecting a component argument from the Facade class in /vendor/laravel/framework/src/Illuminate/Support/Facades/, but isn't getting the component it needs. I checked the page code, and there is definitely a component there.
The Facade function creating the error:
/**
* Handle dynamic, static calls to the object.
*
* #param string $method
* #param array $args
* #return mixed
*
* #throws \RuntimeException
*/
public static function __callStatic($method, $args)
{
$instance = static::getFacadeRoot();
if (! $instance) {
throw new RuntimeException('A facade root has not been set.');
}
return $instance->$method(...$args);
}
And the page that's supposed to be loading its component:
#extends('layouts.app')
#section('content')
#livewire('component')
#stop
Is there a simple way to fix the problem? Or am I missing something?
I got same error like what you get when i try to passing parameter and then i'm solving the problem by following the documentation with changing the way to render livewire component from using blade directive #livewire() into <livewire: >
I'm trying to create my first component in Joomla but I can't understand how it works really :D
I create a basic component with "Component Creator". (I saved a lot of time...).
Now, I have a table in my DB where I've put my data:
id = 1
name = Andrea
note = Ciao
Now, I want to call it from the page using Joomla Language.
On my models/component.php i wrote:
class Variabili extends JModelLegacy
{
function estraivariabili()
{
$db =& JFactory::getDBO();
$db->setQuery("SELECT * FROM #__table")->loadObjectList();
return $value;
}
}
and on my default.php I wrote
$model=$this->Variabili();
//call the method
$items=$model->estraivariabili();
//print
print_r($items);
But on the page I have this error:
0 Call to undefined method Calcolo_imposteViewCalcoloonline::Variabili()
Where is a mistake?
Please be gentle with me because I'm a beginner: D
Thanks in advance
Andrea
You have committed a few wrongs. I've rewritten your functions so that you can get it. Let's have a look-
The model, it looks almost okay. Just change it like-
class Variabili extends JModelLegacy
{
// Make the function public
public function estraivariabili()
{
$db = &JFactory::getDBO();
// Put the result into a variable first, then return it.
$value = $db->setQuery("SELECT * FROM #__table")->loadObjectList();
return $value;
}
}
And now call the model functions not from default.php, rather than write your code inside view.html.php file.
Inside the display function of view.html.php file first, get the model instance by using getModel() function.
$model = $this->getModel();
Now you can get the items by using this $model class instance.
$this->items = $model->estraivariabili();
This will bring you the data from the database table. And you can use the data at default.php file.
Just try at default.php file-
print_r($this->items);
I have a link I am sending via email. For example, www.swings.com/worker?id=3382&tok=jfli3uf
In this case I want the person to click the link, get sent to the login page(which it does) and then be directed to a controller method WITH the $id and $tok variables. I can't get that part to work. Any ideas? I am only using the RedirectIfAuthenticated class and this is what it looks like:
public function handle($request, Closure $next)
{
$user = $request->user();
if ($this->auth->check()) {
if($user && $user->hasRole('worker'))
{
return redirect('worker');
}
return redirect('home');
}
return $next($request);
}
hasRole is a method I created in the User model that checks the role of the logged in user
You can flash data to the session when redirecting by chaining the with() method:
// in your handle() method:
return redirect('home')->with($request->only('id', 'tok'));
// then in home controller method:
$id = session('id');
$tok = session('tok');
AFTER SOME HOURS I WAS ABLE TO HAVE A SOLUTION:
ReturnIfAuthenticated wasn't changed. I just added the following within my controller that this link should go to:
for instance, the route would be:
Route::get('worker', 'WorkerController#methodINeed');
Within this method:
public function methodINeed() {
$id = Input::get('id');
$tok = Input::get('tok');
// Do what I need this variables to do
}
What I didn't understand and what could not be properly understood is that the auth controller in Laravel 5 is triggered when a user is a guest it will still redirect to the actual method with all its original data once auth is successful. Hope this is helpful.
I am using in project Zend Framework 2 with Doctrine 2 ORM.
I am trying to persist a many to many relation. I followed th documentation described here (manytomany).
While trying to persist data: $em->persist($form->getData()); I got the error:
"The class 'Doctrine\ORM\PersistentCollection' was not found in the chain configured namespaces".
Any suggestions ?
To be more clear I added below some code:
First I annotated entities like documentation said, for many to many relation:
/**
* #ORM\ManyToMany(targetEntity="\User\Entity\Client", mappedBy="reportSettings")
*/
private $client;
public function __construct() {
$this->client = new ArrayCollection();
}
and
/**
* #ORM\ManyToMany(targetEntity="\Statistics\Entity\ReportSettings", inversedBy="client")
* #ORM\JoinTable(name="report_client_settings",
* joinColumns={#ORM\JoinColumn(name="client_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="report_setting_id", referencedColumnName="id")})
*/
private $reportSettings;
public function __construct() {
$this->reportSettings = new ArrayCollection();
}
And in the controller
$form = new UpdateReportSettingsForm();
$form->bind($reportSettings);
$request = new Request();
if ($request->isPost()) {
$form->setData($request->getPost());
if ($form->isValid()) {
$data = $form->getData();
$em->persist($data); // here I got the error - The class 'Doctrine\ORM\PersistentCollection' was not found in the chain configured namespaces
$em->flush();
}
I also use in the form DoctrineModule\Form\Element\ObjectMultiCheckbox.
An simple var_dump($data) - return a persistent collection.
The error appear because the form was not defined correctly. The right way how to do a many to many relation i founded here - http://laundry.unixslayer.pl/2013/zf2-quest-zendform-many-to-many/
Have you added this piece of code in the beginning of your entity where you are mapping
use Doctrine\Common\Collections\ArrayCollection;
Ok, I have a User entity as follows
<?php
class User
{
/**
* #var integer
* #Id
* #Column(type="integer")
* #GeneratedValue
*/
protected $id;
/**
* #var \Application\Entity\Url[]
* #OneToMany(targetEntity="Url", mappedBy="user", cascade={"persist", "remove"})
*/
protected $urls;
public function __construct()
{
$this->urls = new \Doctrine\Common\Collections\ArrayCollection();
}
public function addUrl($url)
{
// This is where I have a problem
}
}
Now, what I want to do is check if the User has already the $url in the $urls ArrayCollection before persisting the $url.
Now some of the examples I found says we should do something like
if (!$this->getUrls()->contains($url)) {
// add url
}
but this doesn't work as this compares the element values. As the $url doesn't have id value yet, this will always fail and $url will be dublicated.
So I'd really appreciate if someone could explain how I can add an element to the ArrayCollection without persisting it and avoiding the duplication?
Edit
I have managed to achive this via
$p = function ($key, $element) use ($url)
{
if ($element->getUrlHash() == $url->getUrlHash()) {
return true;
} else {
return false;
}
};
But doesn't this still load all urls and then performs the check? I don't think this is efficient as there might be thousands of urls per user.
This is not yet possible in a "domain driven" way, ie. just using objects. You should execute a query to check for the existance:
SELECT count(u.id) FROM User u WHERE ?1 IN u.urls AND u.id = ?2
With Doctrine 2.1 this will be possible using a combination of two new features:
Extra Lazy Collections
#IndexBy for collections, so you would define #OneToMany(targetEntity="Url", indexBy="location")
ExtraLazy Collection Support for index by using ->contains().
Points 1 and 2 are already implemented in Doctrine 2 master, but 3 is still missing.
You should try using the exists method on the collection and manually compare values.
