Creating a PDF in memory from within a web application
Example Django web application view which generates a PDF in memory and returns it as the result of an HTTP request. This example uses RML as the document source.
RML2PDF is a central component of ReportLab PLUS: a translator which converts high level XML markup into PDF documents. Report Markup Language describes the precise layout of a printed document, and RML2PDF converts this to a finished document in one step.
See the RML User Guide for more information about RML.
from django.http import HttpResponse from rlextra.rml2pdf import rml2pdf import cStringIO def getPDF(request): """Returns PDF as a binary stream.""" # Use your favourite templating language here to create the RML string. # The generated document might depend on the web request parameters, # database lookups and so on - we'll leave that up to you. rml = getRML(request) buf = cStringIO.StringIO() rml2pdf.go(rml, outputFileName=buf) buf.reset() pdfData = buf.read() response = HttpResponse(mimetype='application/pdf') response.write(pdfData) response['Content-Disposition'] = 'attachment; filename=output.pdf' return response
