url method raises an error if I don't have the root method in my model - padrino framework

[ipoval]

def url
if file.respond_to?(:url) and not file.url.blank?
file.url
elsif current_path
File.expand_path(current_path).gsub(File.expand_path(root), '')
end
end

File.expand_path(root) raises an error since root is nil, if I don't define the root method in my model.

I was using the padrino framework + sequel. I suspect that I need to supply some additional configuration hash, but it was not obvious for me why it didn't work by default. If this is my configuration issue, probably, it worth mentioning in the docs the need for some additional config. options.

Thanks, Ivan Povalyukhin
