Helper methods from controller

Hi,

I'm not sure i'm my design is correct, but i have around_filter in the
controller, where i want to add a small javascript at the end of the
page. Is there someway i can use the javascript_tag from the controller?
i though there where a helpers proxy available.

Maybe Im not understanding your situation, but filters are more used for
application logic and typical cases like logging, benchmarking etc.
Wouldnt it be better to use the layouts folder and stick the javascript
in there ?

This will be a plugin that enable auto-refresh with ajax, and the
after_filter is starting the javascript-update-check-script for the
configured actions.

This isn't really how you'd use the before/after filters. What it
sounds like is that you need to be able to trigger js to be called on
specific actions? You might consider adding the js code to your
application layout view... and use a before filter on the specific
actions you want this to run and have that show the corresponding js.

For example:

before_filter :trigger_js_stuff

def trigger_js_stuff
  @reload_page = true
end

In your view...

<% if @reload_page %>
  // trigger your js code here
<% end %>

Good luck!
