I am beginner in sylius work and i would like to create adjustement on order item before it will be persist in database. So i create a listener base on sylius.order_item.pre_create event as it is said in the documentation https://docs.sylius.com/en/1.5/book/architecture/events.html
All Sylius bundles are using SyliusResourceBundle, which has some built-in events on this format for exemple
sylius.resource.pre_create
Her is my Listener Config
services:
app.listener.order_item:
class: App\EventListener\OrderItemListener
tags:
- { name: kernel.event_listener, event: sylius.order_item.pre_create, method: onSyliusOrderItemPreCreate }
Her is my Listener Class
<?php
namespace App\EventListener;
use Symfony\Component\EventDispatcher\GenericEvent;
use Sylius\Component\Core\Model\ShopUserInterface;
use App\Entity\Order\OrderItem;
use App\Entity\Order\Order;
use App\Entity\Order\Adjustement;
use App\Repository\Channel\ChannelPricingRepository;
use Sylius\Component\Channel\Context\ChannelContextInterface;
use Sylius\Component\Order\Factory\AdjustmentFactoryInterface;
class OrderItemListener
{
public function onSyliusOrderItemPreCreate(GenericEvent $event)
{
var_dump(''); die;
$orderItem = $event->getSubject();
Assert::isInstanceOf($orderItem, OrderItem::class);
}
}
But nothing happens when i add a new product to card. What i miss? May be i don't understand well concept or i make thing in wrong way. Please help me.
I have found solution for my problem. In fact when adding product to card route sylius_shop_ajax_cart_add_item is called with post method. Doing bin/console debug:router sylius_shop_ajax_cart_add_item show that Sylius\Bundle\OrderBundle\Controller\OrderItemController::addAction method is excecuted. In this one $this->eventDispatcher->dispatchPreEvent(CartActions::ADD, $configuration, $orderItem); is called and CartActions::ADD = 'add'.
So the event her is sylius.order_item.pre_add not sylius.order_item.pre_create as i made it.
services:
app.listener.order_item:
class: App\EventListener\OrderItemListener
tags:
- { name: kernel.event_listener, event: sylius.order_item.pre_add, method: onSyliusOrderItemPreAdd }
thanks.

FYI: Products is my cms element name.
As shown in shopware 6 guides, I have created a file
DataResolver/ProductsCmsElementResolver.php
which has an enrich method which helps to extend data. In there I try to access the configs of my custom cms element with:
$config = $slot->getFieldConfig();
$productListType = $config->get('products')->getValue();
That, however always returns the default value that was set during the registration of the element:
Shopware.Service('cmsService').registerCmsElement({
name: 'products',
label: 'das.elements.customProductsElement.label',
component: 'sw-cms-el-products',
configComponent: 'sw-cms-el-config-products',
previewComponent: 'sw-cms-el-preview-products',
defaultConfig: {
products: {
source: 'static',
value: ''
}
}
});
I did it exactly as it is shown in the following guides:
https://developer.shopware.com/docs/guides/plugins/plugins/content/cms/add-cms-element
https://developer.shopware.com/docs/guides/plugins/plugins/content/cms/add-data-to-cms-elements#create-a-data-resolver
Could anyone share a sample of code where you get the value of config as a variable and not static value?
What I was doing wrong was that I forgot to write the .value in computed methods:
computed: {
products() {
return this.element.config.products.value;
}
},
However I also found such function call in shopware source codes which was not mentioned in the docs:
methods: {
createdComponent() {
this.initElementConfig('youtube-video');
this.initElementData('youtube-video'); // this line was not present in docs
}
}
I assume you haven't done any further handling of the product data in your config component, as you do not mention it.
I suggest having a look at the default cms components like for example shopware/administration/Resources/app/administration/src/module/sw-cms/elements/product-slider/config/index.js where you can see how product data is handled :)
I have an Api controller with two different actions that take different parameter types.
// GET: users/sample%40email.com
[Route("users/{emailAddress}")]
public IHttpActionResult GetUser(string emailAddress)
// GET: users/1D8F6B90-9BD9-4CDD-BABB-372242AD9960
[Route("users/{reference}")]
public IHttpActionResult GetUserByReference(Guid reference)
Problem is multiple actions are found matching when I make a request to either. Looking at other answers I thought I needed to setup routes in the WebApiConfig like so...
config.Routes.MapHttpRoute(
name: "apiEmail",
routeTemplate: "api/{controller}/{action}/{email}"
);
config.Routes.MapHttpRoute(
name: "apiReference",
routeTemplate: "api/{controller}/{action}/{reference}"
);
What do I need to do so that each action is called based on the parameter type I pass in?
I'm very new to Web.Api any additional explanation text would be appreciated.
You do like below method declaration with attribute routing enabled:
//declare method with guid 1st
// GET: users/1D8F6B90-9BD9-4CDD-BABB-372242AD9960
[Route("users/{reference:guid}")]
public IHttpActionResult GetUserByReference(Guid reference)
and declare other method like below
// GET: users/sample%40email.com
[Route("users/{emailAddress}")]
public IHttpActionResult GetUser(string emailAddress)
Please let me know, is this work for you ?
I'm trying to create a small EmberJS application, but I'm struggling about how to architecture it correctly. I have a main view called "library" which displays on a sidebar a list of folders. User can click on each folder and display the content at the center (while the sidebar is still active).
I therefore have a library resource, and nested resources to display the folders in this specific context:
this.resource('library', function() {
this.resource('libraryFolders', {path: 'folders'}, function() {
this.resource('libraryFolder', {path: ':folder_id'};
}
};
To be able to access the folders in the parent root, I set up a dependency:
App.LibraryController = Ember.Controller.extend({
needs: ["libraryFolders"],
folders: null,
foldersBinding: "controllers.libraryFolders"
});
App.LibraryRoute = Ember.Route.extend({
setupController: function(controller) {
controller.set('controllers.libraryFolders.model', App.Folder.find());
}
});
First question: is this a good way? I feel it a bit strange that a parent controller have a dependency to its children.
Now, another problem arises: what if I want to reuse folders in another context? All the methods I would write in LibraryFoldersController would be specific to this one, not really DRY. What I came up is adding a root "folders" resource, and add the dependency to this one instead:
this.resources('folders');
App.LibraryController = Ember.Controller.extend({
needs: ["Folders"],
folders: null,
foldersBinding: "controllers.folders"
});
App.LibraryRoute = Ember.Route.extend({
setupController: function(controller) {
controller.set('controllers.folders.model', App.Folder.find());
}
});
What do you think? Am I doing it wrong?
IMO it looks good so far. You are using the needs API which is the correct (ember) way to setup dependencies between controllers.
Maybe if you find yourself writing repeating code you could consider creating a Mixin for a more general controller an put there your logic, that should be agnostic to the use cases it handles.
For example defined a mixin:
App.ControllerMixin = Ember.Mixin.create({
// "use case" agnostic logic here
});
You mix mixins into classes by passing them as the first arguments to .extend.
App.LibraryController = Ember.ObjectController.extend(App.ControllerMixin, {
// now you can use here the logic defined in your mixin
// and add custom code as you please
});
Another possibility is to write a super class and then extend from it to inherit common logic:
Snippet taken from the docs:
App.Person = Ember.Object.extend({
helloWorld: function() {
alert("Hi, my name is " + this.get('name'));
}
});
var tom = App.Person.create({
name: 'Tom Dale'
});
tom.helloWorld(); // alerts "Hi, my name is Tom Dale".
One thing worth mentioning (though I think it's simply a typo) is: needs: ["Folders"] should be needs: ["folders"],
Hope it helps.
I want to use a Voter to only allow owners to edit a project object in my application.
I have a route /project/42/edit that invokes my action ProjectController.editAction(Project $project). I use a type hint (Project $project) to automatically invoke the ParamConverter to convert the ID 42 from the URI into a project object. This works nicely for the controller action, however it seems to be invoked too late for the voter. Its vote() method gets called with the request as 2nd parameter, not my project.
Is there a way to pass the project to the voter without having to retrieve it from the database again?
UPDATE: I learned that I have to manually call isGranted() on the security context in the edit method. This is very similar in approach to this answer.
Here is my Voter:
namespace FUxCon2013\ProjectsBundle\Security;
use FUxCon2013\ProjectsBundle\Entity\Project;
use Symfony\Component\BrowserKit\Request;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\Security\Core\Authorization\Voter\VoterInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
class OwnerVoter implements VoterInterface
{
public function __construct(ContainerInterface $container)
{
$this->container = $container;
}
public function supportsAttribute($attribute)
{
return $attribute == 'MAY_EDIT';
}
public function supportsClass($class)
{
// your voter supports all type of token classes, so return true
return true;
}
function vote(TokenInterface $token, $object, array $attributes)
{
if (!in_array('MAY_EDIT', $attributes)) {
return self::ACCESS_ABSTAIN;
}
if (!($object instanceof Project)) {
return self::ACCESS_ABSTAIN;
}
$user = $token->getUser();
$securityContext = $this->container->get('security.context');
return $securityContext->isGranted('IS_AUTHENTICATED_FULLY')
&& $user->getId() == $object->getUser()->getId()
? self::ACCESS_GRANTED
: self::ACCESS_DENIED;
}
}
I register this in configure.yml so that it gets the service container as parameter:
services:
fuxcon2013.security.owner_voter:
class: FUxCon2013\ProjectsBundle\Security\OwnerVoter
public: false
arguments: [ #service_container ]
tags:
- { name: security.voter }
The last block is to configure the access decision manager in security.yml to unanimous:
security:
access_decision_manager:
# strategy can be: affirmative, unanimous or consensus
strategy: unanimous
allow_if_all_abstain: true
Please have a look at this answer i have written yesterday.
You can easily adapt it to your needs by checking for the owner of your object.
The current object doesn't get passed in the voter if you use the role security handler.
I had to extend the latter to get the former.
Don't hesitate to comment for details.
I am trying to get my security stuff setup for symfony2 and I have it working so far, but now I need to do some more fancy things. I am currently using everything dealing with PreAuthentication (I use a third party component for logging in and session management). That part is working great in tandem with the JMS security bundle.
Now I am to the point when I want to catch the users that are throwing 403s so I can just forward them to the login page of the third party component that I am using. I think my best bet is to add an exception handler to the exception listener. I am looking at the AccessDeniedHandlerInterface.
Is this the right direction for me to be going?
How do I add this handler to the exception listener?
EDIT:
I ended up doing something similar. I created a service that is prompted on the kernel.exception event. services.yml looks like this:
services:
kernel.listener.accessDenied:
class: Fully\Qualified\Namespace\Path\To\Class
tags:
- { name: kernel.event_listener, event: kernel.exception, method: onAccessDeniedException }
and the class it self:
<?php
namespace Fully\Qualified\Namespace\Path\To;
use Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent,
Symfony\Component\HttpFoundation\Response,
Symfony\Component\Security\Core\Exception\AccessDeniedException;
class Class
{
public function onAccessDeniedException(GetResponseForExceptionEvent $event)
{
$exception = $event->getException();
//Get the root cause of the exception.
while (null !== $exception->getPrevious()) {
$exception = $exception->getPrevious();
}
if ($exception instanceof AccessDeniedException) {
//Forward to third-party.
}
}
}
This sounds about right.
Or, if you're specifically interested in AccessDeniedException you could also define access_denied_handler within your firewall in security.yml:
security:
firewalls:
my_firewall:
# ...
access_denied_handler: kernel.listener.access_denied.handler
# ...
Then define your service in your services.xml or equivalent:
<parameters>
<parameter key="kernel.listener.security.class">Path\To\Your\Class</parameter>
</parameters>
<service id="kernel.listener.access_denied.handler" class="%kernel.listener.security.class%">
<tag name="kernel.event_listener" event="security.kernel_response" method="handle" />
</service>
The handler class:
use \Symfony\Component\Security\Http\Authorization\AccessDeniedHandlerInterface;
class MyAccessDeniedHandler implements AccessDeniedHandlerInterface
{
public function handle(Request $request, AccessDeniedException $accessDeniedException)
{
// do something with your exception and return Response object (plain message of rendered template)
}
}
