What's this?

image_path(source) public

Computes the path to an image asset in the public images directory. Full paths from the document root will be passed through. Used internally by image_tag to build the image path. Passing a filename without an extension is deprecated.

  image_path("edit.png")  # => /images/edit.png
  image_path("icons/edit.png")  # => /images/icons/edit.png
  image_path("/icons/edit.png")  # => /icons/edit.png

      def image_path(source)
        unless (source.split("/").last || source).include?(".") || source.blank?
          ActiveSupport::Deprecation.warn(
            "You've called image_path with a source that doesn't include an extension. " +
            "In Rails 2.0, that will not result in .png automatically being appended. " +
            "So you should call image_path('#{source}.png') instead", caller
          )
        end

        compute_public_path(source, 'images', 'png')
      end

I would just use the path_to_image. I find that this is what works best. As it says above it can create problems.

Here is my code

Code example

def background_path(background)
  if background
    path_to_image background.file_name.normal
  else
    path_to_image "background_preview.jpg"
  end
end

def flavor_path(flavor)
  if flavor
    path_to_image flavor.file_name.normal
  else
    path_to_image("flavor_preview.jpg")
  end
end

basic but gets the job done and it does not have problem with my pre built paths which are called image_path

image_path
