py3o is an elegant and scalable solution to design reports using LibreOffice or OpenOffice. py3o.template is the templating component that takes care of merging your data sets with a corresponding templated OpenOffice document.

It is plateform independent and does not require LibreOffice/OpenOffice itself to generate an ODF file.

If you want to generate a PDF or any other supported output format you will then need to have a server with either LibreOffice or OpenOffice and to install the py3o.renderserver on it. We also provide a docker image on the docker hub

If you want to have templating fusion & document conversion in one single web service usable from any language with just HTTP/POST you can install py3o.fusion server. Which also exists as a docker image

Python 3 support

py3o.fusion is python3 ready. But, yes there is a but... alas!, you'll need

to install a trunk version of Genshi:

$ # activate your python env...
$ svn checkout genshi_trunk
$ cd genshi_trunk
$ python build
$ python install

We tested this with revision 1271. When genshi 0.8 is released we can officially say we support Python3 out of the box.

Example Usage

Below is an example that you can find in the source code inside the examples directory.

from py3o.template import Template

t = Template("py3o_example_template.odt", "py3o_example_output.odt")

t.set_image_path('logo', 'images/new_logo.png')

class Item(object):

items = list()

item1 = Item()
item1.val1 = 'Item1 Value1'
item1.val2 = 'Item1 Value2'
item1.val3 = 'Item1 Value3'
item1.Currency = 'EUR'
item1.Amount = '12345.35'
item1.InvoiceRef = '#1234'

for i in xrange(1000):
    item = Item()
    item.val1 = 'Item%s Value1' % i
    item.val2 = 'Item%s Value2' % i
    item.val3 = 'Item%s Value3' % i
    item.Currency = 'EUR'
    item.Amount = '6666.77'
    item.InvoiceRef = 'Reference #%04d' % i

document = Item() = '9999999999999.999'

data = dict(items=items, document=document)
