Some time posted a question here about any plugin for helper content flash. I find the Flashobject_helper plugin, but it uses the library flashobject javascript to embed the flash in html and sincerely think this library is horrible.
Then decided to make a helper to use swfobject that is the best how to put flash content on your page and it still leaves compatible with the W3C validators, in addition to allowing you use the expressinstall to update the player to appropriate version.
Swfobject the future will be the standard way to add flash adopted by Adobe.
The plugin is ok and ready to install using the line: script/plugin install http://swfobjecthelper.googlecode.com/svn/trunk/swfobject_helper
To use the plugin is: <% Swfobject_tag = "/ source / of / your / flash.swf": div_id =>"id_of_div"%>
Anyone who wants to access the page of the plugin on google code is: Http://code.google.com/p/swfobjecthelper/
