Error with Header and footer options on Windows platform

[mperez123]

I have the next problem.

I am working with RoR 2.3.8 on Windows platform. Also the server run on windows.

I am trying to create a pdf from html template, layout and partials.

briefly i will try to explain what i am trying to do:

My site is a shopping site, so I need generate a voucher.pdf

This voucher could have many items.therefore the voucher could have many pages.

I need to create a header and footer for each page in the voucher. There's mention that without these options (header and / or footer) works perfectly

I try this in my controller

def generate_voucher
@order = Order.find(params[:id])

unless @order.blank?

 pdf = render_to_string_with_wicked_pdf({:pdf    => 'generate_voucher.html.erb',
                                          :layout => 'voucher.html',
                                          :header => {:html => { :template => 'shared/voucher_header.html.erb'} 
                                                                                                          # Also i try voucher_header.pdf.erb
                                         })

  @order.save_pdf(pdf)

  redirect_to :action => "payment", :id => order.id
end

end

This message throw:

'Template is missing

Missing template shared/voucher_header.html.erb in view path app/views'

I need to use a header and footer on every pages of the pdf file and not display it.

Also when i render a image with wicked_pdf_image_tag diaplay a empty frame with grey border.

Thanks in advance and excuse me.

The header line looks good to me, is shared/voucher_header.html.erb right? or is it shared/_voucher_header.html.erb?
Usually shared is a place to put partials. Passing :template assumes a full correct filename, not the magic stripping of the leading underscore like render :partial does.

Not sure about your issue with images, does windows not work with file:// descriptors?
You can check what is actually being rendered in the html by passing :debug => true in your render.

Thank you very much.

When I paste the url generated in browser this show the image correctly. However in image tag don´t show the image.

Are you using wicked_pdf_image_tag or just image_tag? You can try defining a new helper as mentioned here:
#1

def pdf_image_tag(image, options = {})
  options[:src] = File.expand_path(RAILS_ROOT) + '/public/images/' + image_tag(:img, options)
end

I guess I should really try and get a windows computer together to test this stuff better on that platform

Thanks. I am using pdf_image_tag on windows. My problem now is how could i generate multipages pdf with a standard header and footer (I need repeat these).

You have a lot of flexibility in specifying your headers and footers.
Here, the header is a template, and the footer is built up with some standard text.

render :pdf => 'file',
            :header =>  { :html => { :template => 'shared/header.pdf.erb' } },
            :footer   => {:left => 'REPORT',
                                 :center => Time.now.to_s(:db),
                                 :right => '[page] of [topage]'}
