Does anyone know if there is a method to execute a target method on a  
controller, through the filter logic.

Say I want to execute the “list” method, but first have it go through  
the all the filter logic. Is there a method on ActionController::Filters  
to do this?

Thanks

More info::

I’m developing a rails plugin and I need to hijack the filter chain. I  
load a Controller dynamically and need to be able to execute the filter  
chain.

Ex:

load(‘my\_controller’)  
@clazz = Object.const\_get(‘MyController’)  
@clazz.filter\_chain.each do |filter|  
res = filter.call(@clazz, ?)  
if !res  
return  
else  
@clazz.myAction()  
end  
end

So I’m wondering if looping through the filter\_chain is the best way to  
do this? Is there a method to handle this for me? I don’t really see one  
in the source, but maybe somebody knows how…

Any ideas?

Thanks
