Okay, I've identified pdfkit but with the following code I get a blank pdf
downloaded, I must be doing something wrong...:
from pyramid.renderers import render
from pyramid.response import Response
import pdfkit
import StringIO
result = render('frontend:templates/student_pyp_report.pt',
dict(
title=title,
report=report,
student=student,
pdf=True
),
request=request)
pdffileio = StringIO.StringIO()
pdffileio.write(result)
pdf_as_string = pdfkit.from_file(pdffileio, False) # False means
return it as a string
response = Response(
pdf_as_string,
content_disposition="attachment; filename={}.pdf".format("test"
),
content_type = "application/pdf",
charset="utf-8"
)
#pdffileio.close()
return response
and the pdf_as_string is just this:
