Configure output dir for Assetic in Symfony2

Question

I'd like to globally configure the output dir of where assetic dumps my JS files. Currently, they always go to web/js/*. I want to change this to web/js/compiled/*.

It's possible to specify this at a per-file level: http://symfony.com/doc/2.0/cookbook/assetic/asset_management.html#dumping-asset-files

Can't seem to find a way to set this globally across my Symfony app. Any config parameter I'm missing?

UPDATE

Found an assetic config parameter called write_to. Setting this in config.yml causes the command line assetic:dump to dump files to the new dir, but within twig files the asset_url var still points to the original path.

Answer 1

You should use the property write_to.

in my configuration for exemple I use

# Assetic Configuration
assetic:
    debug:          %kernel.debug%
    use_controller: %kernel.debug%
    read_from:      %kernel.root_dir%/Resources/views/
    write_to:       %kernel.root_dir%/../web/static/

Your ouput string start where ends write_to

for exemple

{% javascripts filter="closure" output='js/main.js'

...

 {% stylesheets filter='compass,?cssrewrite' 
     'default/static/sass/screen.scss' 
     output='css/screen.css' 
 %} 

both will placed respectively in /web/static/js/main.js and /web/static/css/screen.css

assets_base_urls is used to specify base URL's to be used for assets referenced from http and ssl (https) pages.

!! assets_base_urls is also used by {% images %} as the root before output value, but {% images %} doesn't consider write_to when rendering html (only when dumping) so better not using write_to and rely only on output value. More about it in my other post on stackoverflow and in this post on AsseticBundle's github.

Answer 2

You can set the asset path ( assets_base_urls ) for twig to a static path, instead of using the relative path. In your config.yml file, it would look similar to this:

framework:
   templating:
      engines: ['twig']
         assets_base_urls:
            http: [http://path.to-cdn.com]

This will effect asset_url from assetic as well as twig's asset() method. The latter may or may not be desired.
