Version	2.1.1

Summary

I've upgraded VichUploaderBundle from 2.0.1 to 2.1.1. After this upgrade, when I try to show an image with vich_uploader_asset I got this error: "Attempted to call an undefined method named "asset" of class "Vich\UploaderBundle\Twig\Extension\UploaderExtension"."

Previous behavior

Using vich_uploader_asset the url of an image is written in a Twig template

Current behavior

It crashes with an error: "Attempted to call an undefined method named "asset" of class "Vich\UploaderBundle\Twig\Extension\UploaderExtension"."

How to reproduce

My configuration is really simple:

vich_uploader.yaml

vich_uploader:
    db_driver: orm

    mappings:
      logo_event:
        uri_prefix: /images
        upload_destination: '%kernel.project_dir%/public/images'
        namer: Vich\UploaderBundle\Naming\UniqidNamer
        directory_namer:
          service: Vich\UploaderBundle\Naming\SubdirDirectoryNamer
          options: { chars_per_dir: 1, dirs: 2}

base/index.html:

{% if prova.logotipProva %}
    <img src="{{ vich_uploader_asset(prova, 'imatgeLogotip') }}" alt="{{ prova.nom }}" class="img-responsive"/>
{% endif %}

All is working correctly with VichUploaderBundle 2.0.1. If I upgrade to 2.1.1, reloading the index page I got this error:

Attempted to call an undefined method named "asset" of class "Vich\UploaderBundle\Twig\Extension\UploaderExtension".

Offending code:

        return $this->render('base/index.html.twig', [
            'properesProves' => $properesProves,
        ]);

The asset method is not in that class anymore, so I guess you messed up something.
Feel free to re-open if you can provide a project in which it's possible to reproduce the exception.
