Is there a templating system for generating PDFs?

[Ottavio]

I'm looking for a templating system for generating pdf files from pyramid.

Is there something?

Or, in case it does not exist, where can I find information about implementing a new template system?

You can use Chameleon to generate HTML which you'll then give to a PDF
formatter such as the CSS3-capable PrinceXML – that's a commercial
offering though.

An alternative is Apache FOP – that's free, but input is XML, not HTML.

what I'm thinking about is more ore less wrapping reportlab or some other library in a renderer.

FOP is a java program, I don't have java on my servers...

Hi,
I have a solution for this using wkhtmltopdf.

Firstly, render the template, then create a temporaty file, convert it into PDF with wkhtmltopdf, and return the PDF content of the generated file (temporary too) modifying the header list.

...
s = render('myproject:templates/mytemplate.pt',
                   dict(foo=1, bar=2), request=request)
       
# "topdf" gets the template, creates the temporary file, calls "wkhtmltopdf" and returns the pdf content
pdf = topdf(s.encode('utf-8'), page_size='A3', orientation='landscape')
       
response = Response(pdf)
response.content_type = 'application/pdf'
response.headerlist.append(('Content-Disposition', 'attachment;filename=prueba.pdf'))

Regards,
León Domingo

how do you attach it to chameleon?

[Simon Oram]

from cStringIO import StringIO

from pyramid.chameleon_zpt import render_template

from ho import pisa

import mimetypes

def pdf(request):

    buffer = StringIO()

    template = render_template('../templates/invoice.pt')

    template = template.encode('utf-8')

    pisa.CreatePDF(template, buffer)

    type, encoding = mimetypes.guess_type('*.pdf')

    response = Response(content_type=type)

    response.body = buffer.getvalue()

    response.headers.add('Content-Disposition',\

        'attachment; filename=blah.pdf' )

    return response

interesting. I'll try to make it work it with cStringIO because I don't like temporary files :-)

I worked with z3c.rml a while back without problems. I don't think
there is an integration with pyramid, but it's not difficult to work with.

Hi
I just completed a project using both z3c.rml and Chameleon.

I would suggest them for sure.

I use xhtml2pdf  ( http://www.xhtml2pdf.com/ ) and it works well with simple templates. For more advances layouts I create the PDF imperatively using reportlab, but its much easier to use xhtml2pdf. I'm planning to try using a ReST to PDF converter like whatever is used in Sphinx, but I haven't gotten there yet.

You may look into

http://pypi.python.org/pypi/zopyx.convert2/2.4.2.1

which provides a unified API around several PDF converters.

The functionality is also exposed as a web-service through

http://pypi.python.org/pypi/zopyx.smartprintng.server/1.1.1

You use the conversion service from a Python client through

http://pypi.python.org/pypi/zopyx.smartprintng.client/
