Wicked_pdf stylesheet not working on Heroku

Question

I have a Rails app where I use wicked_pdf to generate PDF's. This is all fine and working locally, but when pushed to heroku the PDF does render, but without applying the stylesheet.

Especially for PDF rendering I have a CSS file: app/assets/stylesheets/pdf.css.scss. And in form.pdf.haml I load the stylesheet like this:

  !!!
  %html{lang: "en", "xml:lang" => "en", xmlns: "http://www.w3.org/1999/xhtml"}
    %head
      %meta{content: "text/html; charset=UTF-8", "http-equiv" => "Content-Type"}/
      = wicked_pdf_stylesheet_link_tag "pdf"

As said, it works great locally, but when pushed to heroku, I get this error:

ActionView::Template::Error (No such file or directory - /app/public/pdf.css)

What do I have to do to make this work on heroku?

Edit: I found this Gihub repo https://github.com/jordan-brough/heroku-pdf, which is an example app for using wicked_pdf on heroku. It really helped by adapting the environment.rb to serve a css file from the public folder when requesting a PDF.

I had a similar problem and it took me a while to crack. I ended up using the wkhtmltopdf-heroku gem and the following setup which works both locally and on heroku in addition to proper handling of the debug option:

In controller:

respond_to do |format|
  format.html
  format.pdf do
    render pdf: @profile.name + Date.today.to_s(:number),
           background: true,
           encoding: 'utf8',
           :show_as_html => params[:debug].present?
  end
end

In show.pdf.erb:

<% if params[:debug].present? %>
  <%= stylesheet_link_tag 'documents' %>
<% else %>
  <%= wicked_pdf_stylesheet_link_tag 'documents' %>
<% end %>
... rest of view ...

In config/environments/production.rb:

config.assets.precompile += ['documents.css.scss.erb']

In config/initializers/assets.rb

Rails.application.config.assets.precompile += %w( documents.css )

Hope that this will be of help to someone.

Incredibly helpful. This should be on wicked_pdf's `README.md`. — sambecker, May 10 '18 at 04:36

I tried this solution and wicked_pdf works. But the comment:

"Activating runtime compilation is not the solution, because of the performance hit we take" @David Tuite

and found answer in this comment with non-stupid-digest-assets gem, and works perfectly.

There is a GEM for the wkhtmltopdf binaries to work on heroku without you having to install any binaries in your own repository. It also comes packed with the OSX ( darwin ) binary for development. It worked with PDFKit and probably should work with WickedPDF as well

https://github.com/bradphelan/wkhtmltopdf-heroku

  or in your Gemfile as
    gem "wkhtmltopdf-heroku"

The binary is not the issue here, it renders a PDF fine, only without the css file. This gem only adds the binary. – John Dec 12 '13 at 07:11
