javascript_delay throwing error in wicked_pdf

Question

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.

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 Check it's version, it's probably out of date. – Bronwynbronx

Answer 1

As I said in my comment, your version of wkhtmltopdf is outdated.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.

thanks Mark...I installed 0.11.0 rc2 version. It is working now perfectly with some more functionality that I was in need like "table of content" links....:) – Chaps
