Custom Controller & Generating Admin URLs

Yo! @Bernd

Thanks for the feedback! Yeah sometimes creating something custom in EA is a challenge and it's easy to get lost, however it's cool that you found a way to achieve what you need!

Cheers!

Hey Rudi-T,

Yeah, that's tricky. It's not something that could be done easily, unfortunately. But there're some workarounds. If you're on the PAGE_DETAIL of a User, you can fetch the related User from AdminContext, e.g:

        /** @var User $user */
        $user = $adminContext->getEntity()->getInstance();

just add dd($user) to debug that you get what you need at that point. You should be able to get that AdminContext instance by injecting the EasyCorp\Bundle\EasyAdminBundle\Context\AdminContext service into your controller (or custom action). Or, in theory, it should be fetched from $this->getContext() call in the CRUD controller, but be aware that it may return null sometimes.

I hope this helps :)

Cheers!

Hey Speedyschmid,

Thanks for your feedback! We're really happy to hear you love the tutorial, and moreover the EasyAdminBundle :)

About your question, there's no easy way for this. Well, first of all because menu item and filter are different concepts, though they might provide a similar result. But if you want to do some shortcuts for the filters - you can do it I think, just build the proper URL with corresponding query parameters. To know which query params to use - go to the index page and apply the filter you want, then, look closer to the URL - you would need to build the same query params for the submenu link.

And it should work this way, though it's still not perfect probably, because if you're referencing to topics by ID - it won't work on both: production and local. Because most probably you will have different IDs on production :) But you can try and see if it fits your needs.

I hope this helps!

Cheers!

Just wanted to reply myself, that I found a solution that works for my case - not with a preset filter, but a sort of nested Controller.

If anyone else is interested, here is how I do it:

1. I first inject the TopicRepository inside the DashboardController with DI,
2. I query for the Topics inside configureMenuItems()
3. foreach ($topics as topic) and build an array for the SubMenuItems
   `
   $topics = $this->topicRepository->findAll();
   $questionTopicSubItems = [];
   foreach ($topics as $topic) {
   $questionTopicSubItems[] =

    MenuItem::linkToCrud($topic->getName(), 'fas fa-question-circle', Question::class)
        ->setController(QuestionCrudController::class)
        ->setQueryParameter('topicId', $topic->getId());
   

   }
   `

4. Inside the QuestionCrudController inside createIndexQueryBuilder() i look for the query param and if exists, add the where condition
   `
   public function createIndexQueryBuilder(SearchDto $searchDto, EntityDto $entityDto, FieldCollection $fields, FilterCollection $filters): QueryBuilder
   {

    $queryBuilder = parent::createIndexQueryBuilder($searchDto, $entityDto, $fields, $filters);
   
    $request = $this->requestStack->getCurrentRequest();
    $topicId = $request?->query->get('topicId');
   
    if ($topicId) {
        $queryBuilder->andWhere('entity.topic = :topicId')
            ->setParameter('topicId', $topicId);
    }
   
    return $queryBuilder;
   

   }
   `

Hey Speedyschmid,

Good job finding the solution yourself! Well done! And thanks for sharing it with others ;)

Cheers!
