Question

I couldn’t find much information on this.

I want to compile all css (and js indeed) files into something like this:

css/all-c498dsfbc.css

Right now I’m only able to get these:

css/all.css
css/c498dsfbc.css
css/all.css?v=123

The first one sucks, because it has no cache busting at all.

The second one generates a hash which could be used for cache busting, but for some reason it doesn’t change when I change something in my .css files and then run again this:

$ php app/console assetic:dump --env=prod --no-debug

The third one sucks too because I’m required to change the version manually, as explained here: http://symfony.com/doc/current/reference/configuration/framework.html#ref-framework-assets-version. Also, I don’t think using queries for this is a good idea (I think some browsers or CDN might not like that). It would be much better if the filename was changed: ‘all-c498dsfbc.css’. This is how it’s done in Rails if I remember correctly.

Any thoughts?

EDIT

Seem like this feature is missing, I can’t believe it: https://github.com/kriswallsmith/assetic/pull/190

In our project to ensure that new content won’t be cached by Varnish for each deployment we manually change version – and assets pick that one. I think, it is a common practice. But in our case – it saves it in folder such as web/version-1.2.3/css/all.css.

Our config for framework section:

    templating:
        engines: ['twig']
        assets_version: %release_version%
        assets_version_format: "version-%%2$s/%%1$s"
