I have a common failure page that I may need to render to upon failing some test that occurs in an after_filter method. I''d like to use the after_filter to take over the control of the rendering, like so: def test_for_validity some_boolean = my_test return render(:action => ''disqualified'') unless some_boolean @success_controller ||= controller_name @success_action ||= action_name return render(:controller => @success_controller, :action => @success_action) end In my action, if I do nothing unusual, then I expect to render to the regular place. If I override @success_controller and/or @success_action, then my action code can set up the success target. Unfortunately, when I try to do this, I get a DoubleRenderError, which I am sure is because the default render is already done in my action before I attempt to do either render in the after filter. Can this be done, or do I have to resign myself to only _setting_ the target in the after_filter, and then doing the rendering in the action method itself?

Can I just modify the response somehow in my after filter perhaps?

It looks like theoretically, at least, I could manipulate the response body directly, which I think implies that I would be rewriting render to a degree. Of course, it''s all a non-issue unless I could override the default rendering behavior.

In AWDWR v.1, p. 326, there''s an example of directly manipulating the response body. Has anyone else done this and can you vouch for the safety of the process? I would have to process whichever template content that I wanted to return and then put that result of that rendering into the response body, right?

As it turns out, this is a non-issue. But one way that you _could_ get similar behavior would be to use redirect_to in a before filter to respond to the test, whatever it is. But in order to do this, you would have to always redirect_to every action that the before filter was applied to, in order to get the before filter to run. Bottom line: It would be nice to have the ability to control/impact rendering for an action outside of the action method itself.

Re: Using after_filter to control rendering on actions
You can definitely modify the response in an after_filter: we have a bunch of actions that produce xml, and an after filter that runs the xml through an xslt filter (and the user only ever sees the resulting html) Fred -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Right, but I can''t control _what_ is rendered into HTML/XML whatever easily. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
