Appy

Beginners issue with nested dos

Asked by David Björkevik

Hi! I'm trying out appy.pod as a report generator. I try to set up a really minimal example with a ods template using conditional columns, which causes an exception in appy. Have I just got things very wrong or does this simple use case trigger a bug?

Code is below. appytest.ods is at http://www.bjorkevik.se/david/appytest.ods

#####################

from appy.pod.renderer import Renderer

staff = [{'firstName': 'Delannay', 'name': 'Gaetan', 'age': 112},
         {'firstName': 'Gauthier', 'name': 'Bastien', 'age': 5},
         {'firstName': 'Jean-Michel', 'name': 'Abe', 'age': 79}]

renderer = Renderer('appytest.ods', {
                                     "staff":staff,
                                     "print_age": False
                                     }, 'result.ods',
                    overwriteExisting=True)
renderer.run()

Forgot to add the traceback I get from running this:
Traceback (most recent call last):

    if hasattr(mainElem, 'OD'): mainElem = mainElem.OD.elem
AttributeError: 'NoneType' object has no attribute 'elem'

The template file is made using LibreOffice 4.1.6.2. For the above test i use the bzr trunk head, but it crashes in a similar way with latest stable release.

Hi David,
The conditional inclusion of columns is a tricky thing and does not work yet. If you remove your 2 "do cell" statements, it should work.
Cheers,
Gaetan
