Filter Tabs in Sonata Admin

When working regularly with Sonata bundles, you’ve might come accross their MediaBundle, which integrates a media management module. You certainly recognized that there is something different in the list view: A tabbed navigation to filter media items. This is how it looks like in the current 2.3 branch:

I think this is very useful, because you can filter very quickly – literally with one click – instead of wasting three steps on the datagrid (focus widget, select/type value, click filter button). Unfortunately the tab feature is not documented, so I tried to figure out how it works. Here is a tutorial how you can add filter tabs to your own Sonata Admin modules.

Some custom Capifony tasks

Here are some custom made tasks for Capistrano, which might be helpful in the Symfony2 context. First, some cache clearing tasks, that don’t clear the whole cache but only translations or the Twig template cache.

namespace :foo do

  # Clear only translation cache
  task :clear_translation_cache do
      now =
      timestamp = now.strftime("%Y%m%d%H%M%S")
      run "[ -d #{latest_release}/app/cache/prod/translations ] && mv #{latest_release}/app/cache/prod/translations #{latest_release}/app/cache/prod/translations_#{timestamp} || echo 'no translation dir'"

  # Clear only twig cache
  task :clear_twig_cache do
      now =
      timestamp = now.strftime("%Y%m%d%H%M%S")
      run "[ -d #{latest_release}/app/cache/prod/twig ] && mv #{latest_release}/app/cache/prod/twig #{latest_release}/app/cache/prod/twig_#{timestamp} || echo 'no translation dir'"


The folder is accually not removed but renamed to not interfere with current processes. The folder is then automatically rebuilt by the framework.

Symfony2 has that great “assets version” feature, which adds a parameter to the URL of all assets. Then by changing the value, you can make sure that everyone has to load the latest version from the server. If you want to update the asset version automatically on every deploy, you might use the following setup:

Add a file app/config/assets_version.yml to your project containing:

    assets_version: AsSeTvErSiOn

Add that file to the import section of your config.yml and use the parameter %assets_version% in the configuration.

Call that Capistrano task in your deployment process. It replaces the assets version with a value generated from the release name. It is the hexadecimal representation of the YYMMDDHHII timestamp.

namespace :foo do

  # Update asset version
  task :update_version, :roles => :web, :except => { :no_release => true } do
    capifony_pretty_print " --> Update assets version"
    file_path = "#{release_path}/app/config/assets_version.yml"
    assets_version = release_name[2, 10] # Extract YYMMDDHHII only
    assets_version = assets_version.to_i.to_s(16) # Convert to int, convert to hex
    capifony_pretty_print "     Assets version is #{assets_version}"
    run "echo 'parameters:\n    assets_version: #{assets_version}' > #{file_path}"
