Probably, include them into the controller you need, or into  
ApplicationController to make them available everywhere.

But I don’t know, haven’t touched Rails in awhile. Ask the Rails list.

You can specify “helper :all” in ApplicationController.rb, which will  
make  
all helpers available to all controllers and views.

They are available in views already.

For a method to be available both in controllers and views, define it as  
a method in the ApplicationController instead:

private  
def my\_helper(foo)  
return “#{foo}!!”  
end  
helper\_method :my\_helper
