How to prepend assets version to css and js?

问题

I want assetic to output compressed js and css to something like this: v2.3.1/css/whatever.css

Currently this is how I dump my css and js for production: $ php app/console assetic:dump --env=prod --no-debug. But they get dumped into css/ and js/, without the version.

I have read this but it seems to refer to images only, not css/js.

An important reason for doing this is for cache busting/invalidation.

Yes, known issue... In our production workflow we ended up with such block in bin/vendors script:

if (in_array('--env=dev', $argv)) {
    system(sprintf('%s %s assets:install --symlink %s', $interpreter, escapeshellarg($rootDir . '/app/console'), escapeshellarg($rootDir . '/web/')));
    system(sprintf('%s %s assetic:dump --env=dev', $interpreter, escapeshellarg($rootDir . '/app/console')));
    system(sprintf('%s %s myVendor:assets:install --symlink ', $interpreter, escapeshellarg($rootDir . '/app/console')));
} else {
    system(sprintf('%s %s assets:install %s', $interpreter, escapeshellarg($rootDir . '/app/console'), escapeshellarg($rootDir . '/web/')));
    system(sprintf('%s %s assetic:dump --env=prod --no-debug', $interpreter, escapeshellarg($rootDir . '/app/console')));
    system(sprintf('%s %s myVendor:assets:install ', $interpreter, escapeshellarg($rootDir . '/app/console')));
}

As you can see, we defined our console command, which installs assets into web folder after installing and dumping of Symfony's assets. In the MyVendorCommand script we do something like this:

$version = $this->getContainer()->getParameter('your_version_parameter');
$assetsInstallCommand = $this->getApplication()->find('assets:install');

$commandOptions = $input->getOptions();

$assetsInstallArguments = array(
    'command' => 'assets:install',
    'target' => 'web/version-' . $version,
    '--symlink' => $commandOptions['symlink']
);

$assetsInstallInput = new ArrayInput($assetsInstallArguments);
$returnCode = $assetsInstallCommand->run($assetsInstallInput, $output);

Ho, its a big Symfony2 bug ! I am not sure anyone reported it !

My solution was to add an alias in the Nginx config, but your is def. cleaner & better.

My workaround is to make a rewriteRule in .htaccess file in order to serve the real file, but accepting the full url with version number. Something like this ...

app/config/config.yml

[...]
engines: ['twig']
assets_version: 20140523  # numeric version
assets_version_format: "assets-%%2$s/%%1$s"
[...]

web/.htaccess

[...]
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^assets-([0-9]*)/(.*)$ ./$2 [L]
[...]
