I actually generate PDF with WickedPDF on my app. And now I just want to include an image "logo.jpg" on the header of my PDF.

I tried lot of things, and I think my problem come from assets.

My Controller :

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

layouts/application.pdf.erb :

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

pdf/pdf_view.pdf.erb :

<div>
    <p>Just a simple text on my pdf that is correctly displayed</p>
  <%= wicked_pdf_image_tag "images/logo.jpg", :width=>"250", :height=>"200" %>
</div>

And in my console :

Rendering pdf/pdf_view.pdf.erb within layouts/application.pdf.erb
  Rendered pdf/pdf_view.pdf.erb within layouts/application.pdf.erb (2.7ms)
[wicked_pdf]: ["/home/vincent/.rvm/gems/ruby-2.7.1/bin/wkhtmltopdf", "file:////tmp/wicked_pdf20210503-14279-o2q5ol.html", "/tmp/wicked_pdf_generated_file20210503-14279-1om4oam.pdf"]

  Rendered text template (0.1ms)

So my question is : Do you have an other method to display an image on a generated pdf ? Or is my method wrong ?

Problem solved, the right command to display my images on the pdf is :

image_tag wicked_pdf_asset_base64
