Rails - May 2007 - Ruby script that uses rails views?

Hi All,

    I want to write a ruby script that I can launch via a cron job
once a night.

    This script would need to access a rails app that''ve created, it
would need to render a xml builder view in the app to text and save
the text as a xml file.

    I''ve already written the rails view and and I have corresponding
controller action.

    Is it possible to run a rails controller action from a ruby file
and saves its output to a file? Does anyone have any examples of how
one might do this? If you can''t run a controller action, is there
anyway to render a rails view to text from a ruby script?

    Thanks in advance,
    Janak

For running an action from a script take a look at script/runner.

To save the contents of a rendered view to a file you can either turn on 
caching for that action and grab that resulting view or you can use 
render_to_string and then save that string to a file explicitly.
