ReportLab and Django - templates? ; FK object has no attribute split


Depending on what you need to do....
You could shell down and run FOP from Apache foundation which is xml,
xslt to pdf
Or if you are filling in a form, you can use Adobe LiveCycle to define a
form and use code like below to fill in the form

def getPDFContent(id):
values = getAllValues(id)
code = values
completedfdf = getCompletedForm(values)
pdffilename = PDFTemplateMapper.get(code, None)
if pdffilename==None:
raise "No PDF Template defined for %s" % code
pdfpath = os.path.join(ThisDirectory, 'forms')
pdfpath = os.path.join(pdfpath, pdffilename)
pdftk =
cmd = '%s %s fill_form - output - flatten' % (pdftk, pdfpath)
proc = Popen(cmd, stdin=PIPE, stdout=PIPE, stderr=PIPE,
shell=True, bufsize=100000000)
cmdout,cmderr = proc.communicate(completedfdf)
if cmderr != '':
raise cmderr
return cmdout

Hi Victor,

It really depends on complexity of your PDF. I needed to do
something similar some time ago and used ReportLab addon called "pisa"
and used standard Django template language to define the PDF contents.

You might want to take a look, it worked well enough for simple PDF
pages.

Cheers

Jirka
