AssetVersion¶ ↑

Has the Rails asset versioning let you down? AssetVersion ensures your users NEVER load out of date assets. Cached assets include this version in the file name so a version change guarantees a new request from the client.

This works only for javascript and stylesheets referenced with the :cache option.

Example¶ ↑

If you’re using capistrano, AssetVersion will automatically grab version information from your SCM on deploy. Otherwise you can manually set the AssetVersion in your environment.rb or an initializer like so:

AssetVersion.version = 'version_one'

Now when you use javascript_include_tag or stylesheet_link_tag with the :cache option, it will automatically include the version in the filename.

javascript_include_tag('application', 'extra', :cache => 'all')
#=> <script type="text/javascript" src="/javascripts/all_version_one?123456789"></script>

If necessary, you can override the version information on a per call basis by supplying a :version option.

stylesheet_link_tag('application', 'blueprint', :cache => 'all', :version => 'version_two')
#=> <script type="text/javascript" src="/stylesheets/all_version_two?123456789"></script>
