Environment:- Ruby - 1.9.3 , Rails - 4.0.0

I am generating pdf using wicked_pdf gem.

For this, I used below code in my controller:-

respond_to do |format|
    format.html
    format.pdf do
        render :pdf => 'contractors_data',
               :javascript_delay => 5000,
               :disposition => 'attachment',
               :template => 'tiles/templates/pdf/contractors.pdf.erb',
               :header => { :right => 'Page [page] of [topage]' }

end

In this pdf, I am generating a graph using $.plot method of javascript/jquery. So I want to wait pdf generator to wait till $.plot not respond and not plot graph over pdf.

I am sure and confirmed that javascript and jquery are working on this page as I used using wicked_pdf_javascript_link_tag for this.

Now I used :javascript_delay => 5000 in respond_to format option. But it is throwing error in generating while :redirect_delay => 5000 are working properly.

I tries this in cmd prompt also. I am getting error on cmd similar to GUI working.

Please answer with good solution. If possible, please provide code also for reference.

• 1 wicked-pdf is just a thin wrapper for wkhtmltopdf. That error means that your version of wkthmtltopdf does not have the javascript-delay option. Check it's version, it's probably out of date. – Mark Commented Oct 18, 2013 at 12:45

As I said in my ment, your version of wkhtmltopdf is outdated. The javascript-delay option was introduced in version 0.10.0. Here's the manual for 0.9.9, you'll see no such option.
