Cannot access image_path in library class

Rails
#1

Hi @ all,

In a rails application I have a nested module in my library:

module Foo
  module Bar
    def foo_bar
      image_path("my_asset.png")
    end
  end
end

Within foo_bar i can use image_path, a rails helper, without any
problems. It finds the asset int the asset-pipeline and constructs the
path.

When I now add a class inside this module, I cannot access image_path,
and therefore my asset, anymore like shown in the following example:

module Foo
  module Bar
    class FooBar
      def foo_bar
        image_path("my_asset.png")
      end
    end
  end
end

I get a NoMethodError as shown below.

NoMethodError - undefined method `image_url' for

#Foo::Bar::FooBar:0x007fe279d08280:

Why can’t I access image_path anymore, or what changes do I need to
get this working?

Thanks in advance,
Martin

Might be a typo? Your second code snippet has my_assset.png

Sorry, it’s not the typo. I changed the example.
However, that would not be the problem. The problem is that it can’t
access the helper function.
