Great, thank you very much, this got me started. However, its not
working yet. This is the code i have right now:
def generate_pdf(request):
response = HttpResponse(mimetype='application/pdf')
response['Content-Disposition'] = 'attachment; filename=somefilename.pdf'
styles = getSampleStyleSheet()
Document = [Paragraph('rd', styles["Title"])]
Document.append(Spacer(1,50))
date_now = unicode(datetime.now().strftime("%B %d, %Y"))
Document.append(Paragraph("PDF created on " + date_now, styles["Normal"]))
Document.append(Spacer(1,10))
doc.build(Document)
return response
But instead of showing the pdf i get the error:
Exception Type: IndexError
Exception Value: list index out of range
I cannot imagine what may be wrong there? From my point of view it
should work like that?
Greetings
Sven
