django generate pdf with tables and charts

[Jaimin Patel]

I am trying to generate pdf using django template, also need some support of javascript code. I have tried PISA, ReportLib and wkhtmltopdf but it seems that it doesn't wait for Javascript. 

Can someone suggest good solution or example?

Django doesn’t run Javascript, that’s done in the browser. If you really want to have JS processing you’ll have to open a web browser and then print to PDF.

You could send a request using Ajax, to a cgi program on the server, and include the URL. The program would pull the content and convert to pdf, then return the URL of the document. If the user has to be authenticated to view the content, then you would have to pass the authentication key to the CGI program. You may find something like html2pdf will do the conversion, there are free and non-free programs available.

Hello, can you explain us better what you means with *does not wait for JS* ? 

I understand you say: pdf is rendered w/o running JS code.

Sure.

I had tried to render PDF with pisa,

    template = get_template(template_src)

    context = Context(context_dict)

    html  = template.render(context)

    result = StringIO.StringIO()

    pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), result, link_callback=fetch_resources)

    if not pdf.err:

        return HttpResponse(result.getvalue(), mimetype='application/pdf')

    return HttpResponse('Errors<pre>%s</pre>' % escape(html))

Also tried with wkhtmltopdf -

from wkhtmltopdf.views import PDFTemplateResponse

......

return PDFTemplateResponse(request, 'pdf/pdftemplate.html', {

            'pagesize':'A4',

           'user': results['user'],

           'question': results['question_obj'],

       })

In both cases it doesn't render the elements which I am populating with help of onload javascript function.
