How to display an item list from a twig template

[Richard]

Hi,

I designed my homepage/layout to show :

- my logo/app title/sidebar

- a href in this sidebar routing to my admin page (standard Sonata:Core:Dashboard) to manage all my items ("Book", "Category", "Reader" for example)

- and I want to display in the center of this homepage, the sonata list of my item "Book"

=> In my twig template, I have to know specifically the route to my item Book/list. How can I do this ?

Is there a better way to do what I want ?

Thanks for your help ;-)

Nobody can help me ? :-(

Perhaps I'm not clear enough with my explanations. If so, I can explain a bit more.

In some templates, i use soemthing like :

{{ path('admin_yourapp_yourbundle_yourentity_routename', {'id': object.id}) }}

For AcmeDemoBundle the route could be admin_acme_demo_book_list

I find this out by trying this in the console, it gives all routes registered, including thos of sonata admin :

php app/console router:debug

Thanks for your answer.

In twig templates, the use of {{ path('my_route') }} returns the url. It's a good way when I want to add a href in my template.

But I have to display the content instead of the hyperlink.

I found the render twig function, which can be used to call a controller's action, like {% render "MyAppBookBundle:Book:list" %}

And so, the listAction in my controller could be :

public function listAction()

    {

        return $this->redirect($this->generateUrl('admin_myapp_bookbundle_book_list'));

    }

But I got the above error :

An exception has been thrown during the rendering of a template ("Error when rendering "http://dev.localhost/app_dev.php/" (Status code is 302).")

Any idea ? or another way ?

Another info :

In an another AdminController (which extends CRUDController instead of Controller), the same type of call just works well :

public function saveAction()

    {

        ......

        return $this->redirect($this->generateUrl('admin_myapp_bookbundle_book_edit', array('id' => $book->getIdbook())));

    }

So I tried to implement my listAction function in a similar controller, but I got this error now :

An exception has been thrown during the rendering of a template ("There is no `_sonata_admin` defined for the controller `MyApp\BookBundle\Controller\BookAdminController` and the current route `_internal`")

[Richard]

In fact, this error is fired even if my saveAction function is not implemented.

I think that the twig cannot communicate with my BookAdminController, but why ?

I don't understand this error message :-(

Any help would be appreciate.
