Hi all,

I have a shared partial that calls a helper function render\_foo.

I also have render\_foo defined in Control1Helper and Control2Helper  
(each slightly different)

However, rails seems to only use the render\_foo version in  
Controller1Helper even when I am responding from Controller2.

Is this a correct behavior?

Thanks.

By default on rails 2.0 you’ll get helper :all in your application.rb  
So all helpers get loaded up into all views in all controllers, if 2  
of those modules end up defining a function with the same name then 1  
of those will win, and it will be the same thing for all controllers.  
You can get back the pre rails 2 behaviour by removing the helper :all
