django - pisa : adding images to PDF output

Question

I\'m using a standard example from the web (http://www.20seven.org/journal/2008/11/pdf-generation-with-pisa-in-django.html) to convert a django view / template into a PDF.

Answer 1

I could not get images to appear despite trying every solution I could find on google. But this fudge worked for me as the command line version of pisa displays images ok:

    from tempfile import mkstemp

    # write html to a temporary file
    # can used NamedTemporaryFile if using python 2.6+
    fid, fname = mkstemp(dir='/tmp')
    f = open(fname, 'w+b')
    f.write(html)
    f.close()


    # now create pdf from the html 
    cmd = 'xhtml2pdf "%s"' % fname
    os.system(cmd)
    os.unlink(fname)

    # get the content of the pdf
    filename = fname+'.pdf'
    pdf = open(filename, 'r')
    content = pdf.read()

    pdf.close()
    os.unlink(pdf.name)

    # return content
    response = HttpResponse(content, mimetype='application/pdf')
    response['Content-Disposition'] = 'attachment; filename=draft.pdf'

This worked where the images had either a url or the full path name, eg.
