Include ActionView::Helpers in Rails 3?

Rails

How do you do the equivalent of:

module MyLibrary
include ActionView::Helpers::AssetTagHelper
end

…in Rails 3?

I’m trying to upgrade my app from 2.3.9 to 3.0.1 and I have some stuff
in /lib that needs to include these helpers from ActionView. It works
fine in 2.3.x, but in 3.x it’s giving me the error:

undefined local variable or method `config’

One of the methods in AssetTagHelper now tries to access
controller.config.perform_caching, but since no controller exists in
my library, it flips out. Any way around this?

Thanks!

Ok, here’s my solution, but it feels dirty… it’d be nice if somebody
knew if there was a “proper” solution.

Anyway, I added the following methods to my module. I used extend so
I’m using self on these, but since you’re using include, you can drop
the self part.

def self.config=(controller)
@controller = controller
end
def self.config
@controller
end
def self.controller
@controller
end

I just call call the config= method with a controller object; if you
don’t have one, you’ll have to gain access to it somehow.
