Adding Images to Wicked_pdf cover (rails)

Question

I'm trying to create a cover page that has an image

Using wicked_pdf the cover just renders the absolute path of the image. Any help greatly appreciated.

Here's the code snippet in the controller

      format.pdf do
      render pdf: "MNAZ_Directory", template: '/members/directory.pdf.erb',
              :cover =>'/members/cover.pdf.erb',

              :show_as_html => params[:debug].present?,
              :orientation => 'landscape', 
              :layout => 'pdf',

Answer 1

您可以在cover.pdf.erb文件中尝试此操作

<%= wicked_pdf_image_tag('foo') %>

Answer 2

I had the same issue and fixed it by adding render_to_string() . Please see the sample code below.

respond_to do |format|
  format.pdf do 
    render  pdf: "MNAZ_Directory",  
            template: '/members/directory.pdf.erb',
            layout: "pdf",
            cover: render_to_string("/members/cover.pdf.erb"),
            show_as_html: params[:debug].present?
  end
end
