I'm attempting to convert html to pdf on the fly with HTMLDOC.
The fly in the ointment appears to be that the generated pdf is not
viewable in that it opens Adobe Reader and gives a warning This PDF
document might not be displayed correctly.
The model creates the filename as a slug appended with pdf creates a dict
of the variables and calls
def generate_or_serve_pdf( self, saving = False ):
"""
Return a link to the PDF of this CV, generating one only if
necessary.
"""
self.filename = "%s.pdf" % self.slug
pdfurl = os.path.join( settings.MEDIA_URL, "pdf", self.filename )
pdfpath = os.path.join( settings.MEDIA_ROOT, "pdf", self.filename )
if saving == True or not os.path.exists( pdfpath ):
super( CVMask, self ).save()
url = """%s/%s/""" % ( settings.CVBASE, self.slug )
pdfgen( url, pdfpath )
#return pdfurl
else:
return pdfurl
pdfgen is
def pdfgen( url, outputfile = None, testing = False ):
"""
Generate a PDF file from the supplied URL and write
it to outputfile when complete:
>>> pdfgen("http://www.google.com";, "testpdfgen.pdf", testing = True )
"""
if os.path.exists( outputfile ):
os.unlink( outputfile )
worker = subprocess.Popen( """htmldoc --webpage "%s" --linkstyle plain
--footer ... --no-compression -t pdf14 > %s_tmp""" % ( url, outputfile ),
shell = True, stdout = subprocess.PIPE, stderr = subprocess.STDOUT )
worker.wait()
os.rename( outputfile+"_tmp", outputfile )
and then saves the result to a pdf file in /media/pdf
but somewhere it would appear that the html is being lost and therefore not
being converted or something.
Using XHTML2PDF it all works fine but with some horrible inconstencies in
the rendering and just want to try this to see if it is better but if the
pdf isn;t generated in the first place I can't do that.
