Symfony 2可捕获的致命错误：传递给Sg \\ DatatablesBundle \\ Datatable \\ :: __ construct（）的参数1必须是的实例

Question

I'm using stwe/DatatablesBundle for symfony 2 ( http://github.com/stwe/DatatablesBundle ) (stable version v0.6.1) and getting the following error:

Catchable Fatal Error: Argument 1 passed to Sg\\DatatablesBundle\\Datatable\\View\\AbstractDatatableView::__construct() must be an instance of Symfony\\Bundle\\TwigBundle\\TwigEngine, none given, called in G:\\server\\www\\bongoapp\\app\\cache\\dev\\appDevDebugProjectContainer.php on line 418 and defined

I have tried following the answer here , but it is not working for me. What am I doing wrong? Code below and thanks in advance:

    return $datatable->getResponse();

  bbd_datatables.artist:

     tags:

and index.html.twig

{% block javascripts %}
{{ parent() }}
{{ datatable_render_js(datatable) }}

Answer 1

It seems like you've used the wrong tag.

bbd_datatables.artist:
   class: Bbd\BongoAppBundle\Datatables\ArtistDatatable
   tags:
      - { name: sg.datatable.view }

Look: https://github.com/stwe/DatatablesBundle/blob/master/Resources/doc/example.md#step-3-registering-your-datatables-class-as-a-service

Answer 2

I could fix this by using the parent argument in the config:

bbd_datatables.artist:
    class: Bbd\BongoAppBundle\Datatables\ArtistDatatable
    parent: sg_datatables.datatable.abstract
    tags:
        - { name: sg.datatable.view }

This pulls the argument declaration required for the AbstractDatatableView .
