ReportLabs is a great tool, but you have to watch your permissions.
I would put a sample bit of code into createPdf.py, and try running it
firstly as root
to confirm the createPdf.py works, and then as your apache user;
su -u www-data python createPdf.py
I would suspect that the line c.save() throws an error due to write
permissions.
Another thing you may look at - you can pass anything that looks like
a file into Canvas.
I use a fileobject which i leave up to the python temp file code to
handle.
Once i have my temporary file, i pass that to Canvas like this;
myCanvas = canvas.Canvas(self.fileobject, pagesize=self.pagesize)
(self.pagesize is set somewhere else)
then i do all my drawing, and then save and rewind the file ;
myCanvas.save()
self.fileobject.seek(0)
then i can do this (django-specific code here);
response = HttpResponse(label.fileobject.read(),
mimetype =
'application/x-pdf')
