Wicked-PDF not showing images, 'wicked_pdf_image_tag' undefined

Use the wicked_pdf_image_tag helper in your view and reference the image with asset_url if your image is in public/images or use asset_pack_url if the image is in public/packs/media/images

<%= wicked_pdf_image_tag asset_url('/images/footer_logo.png') %>

or

<%= wicked_pdf_image_tag asset_pack_url('media/images/footer_logo.png') %>

First thing create a pdf template to render and use your wicked_pdf tags in that template.. for example-

app/views/layout/application.pdf.erb-

<!doctype html>
<html>
  <head>
    <meta charset='utf-8' />
  </head>
  <body onload='number_pages'>
    <div id="content">
      <%= yield %>
    </div>
  </body>
</html>

app/views/pdf/pdf_view.pdf.erb-

<div>
  <%= wicked_pdf_image_tag 'logo.jpg' %>
</div>

use this template instead

def save
  pdf = WickedPdf.new.pdf_from_string(
                        render_to_string(
                          template: 'example/pdf_view.pdf.erb',
                          layout: 'layouts/application.pdf.erb'))
  send_data(pdf,
            filename: 'file_name.pdf',
            type: 'application/pdf',
            disposition: 'attachment') 
end
