Dear list,

A client of ours requested a site which has a different background for  
each page(don’t flame me, I just build it). The background depends on  
stuff I pull from the DB. I planned on using an after\_filter to set an  
instance variable containing the background. Can’t do it in a before  
filter as the background depends on stuff that happens in the actual  
action.

But, as I figured out and in retrospect it makes perfect sense, the  
after\_filter is ran after the action is already rendered. No good for  
me.

So my question really is; how can I made a method which is ran after  
all actions?

With kind regards,  
Harm

you could override render().

def render(\*args)  
some\_after\_filter()  
super(args)  
end

Thats what I came up with last night(sleeping is overrated)! I think  
I’ll implement that. Thanks a lot!
