Using Twig functions in admin panel

With CMS 2.0+, you can use some Twig functions in the admin panel content. It's extremely helpful if you wish to render a block within a page, or what's even more common - a media, for instance an image or video.

So far, only following functions are allowed:

parameters:
    bitbag_cms.twig.admin_functions:
        - bitbag_cms_render_block
        - bitbag_cms_render_media

As this is a parameter, you can easily customize its value in your config.yml.

Note:

With the parser, you are supposed to use the function with {{ function_name('foo', 'bar') }} format. All characters, including spaces and apostrophes are recognized. Only string parameters are allowed.

If for some reason the function would not be able to execute, an empty string result will be returned.

To render the interpretable content, you need to use a special {{ bitbag_cms_render_content([resource]) }} Twig function. The resource needs to implement ContentableInterface. For an example, take a look at the Block's show.html.twig file.
