wicked_pdf doesn't work after rails update

Question

Hi this is not a question, but a solution for a problem :)

I updated rails from 5.1.x to 5.2.x, at this new rails version by default updates sprockets from 3.x.x to 4.x.x version. Therefor if you are using wicked_pdf gem older version you might encounter problem like this:

ActionView::Template::Error:
       undefined method `pathname' for #<Sprockets::Asset:0x0000564070ad65e0>

I was using wicked_pdf version 1.1.x. And i didnt found any similar issues. So after some time going trough the code i found out that older wickedpdf gem tries to get pathname from the asset and sprockets => 4.0.0 doesn't support pathname and uses filename

old gem code:

  asset ? asset.pathname : File.join(Rails.public_path, source)

new gem code:

if asset
  # older versions need pathname, Sprockets 4 supports only filename
  asset.respond_to?(:filename) ? asset.filename : asset.pathname
else
  File.join(Rails.public_path, source)
end

So in conclusion if you updated your sprockets to v4 you must update your old wicked_pdf gem also.
