Hello everybody,

I found a cool helper for generating dependant select controls by  
Dimitrij Denissenko, which I don’t quite know how to install it. The  
structure of the helper is as follows:

module ActionView  
module Helpers  
module RelatedSelectFormOptionsHelper  
…  
end  
end  
end

So, I tried to stick it in my app/helpers and do  
“helper :related\_select\_form\_options” in a controller, which produces  
exactly this: “app/helpers/related\_select\_form\_options\_helper.rb to  
define RelatedSelectFormOptionsHelper”

If I put the thing into the site helpers directory, I get “couldn’t  
find related\_select\_form\_options\_helper.rb”.

So, I don’t quite know how to proceed from here. What’s the best way  
to do it?

Solved. Hope it will help somebody. Basically, after some extensive  
research  
I found out that the way to do it is to put the code in a file and then  
“require” it from environment.rb. Found the answer here:
