RE: Webservice return pdf

Here's how I merge .fdf with pdf

def getPDFContent(assessment):
completedfdf = getCompletedForm(assessment)
pdffilename = getFilename(assessment, 'forms') +".pdf"
pdftk = ["/usr/bin/pdftk" ,'pdftk'][os.name=='nt']
cmd = '%s %s fill_form - output - flatten' % (pdftk,
pdffilename)
proc = Popen(cmd, stdin=PIPE, stdout=PIPE, stderr=PIPE,
shell=True, bufsize=100000000)
cmdout,cmderr = proc.communicate(completedfdf)
if cmderr != '':
raise cmderr
return cmdout

and here's how I do my response (from views.py)
def getpdf(request, *args, **kwargs):
qs = extract_querystring_from_request(request)
parameters = Parameters(**qs)
assessment = models.Assessment.objects.get(pk=parameters.id)
pdfbuffer = pdfgenerator.getPDF(assessment)
response = HttpResponse(mimetype='application/pdf')
response['Content-Disposition'] = 'inline; filename=filename.pdf'
response.write(pdfbuffer)
return response

I'm no expert, but this works consistently.
