** Summary changed: - utils.calculate_cloud can leave font_size unset for most frequent tag + utils.calculate_cloud() can leave font_size unset for most frequent tag
** Description changed: Binary package hint: python-django-tagging - This is a long standing issue on Google Code, issue 91: + Current version of package ``python-django-tagging'' has a long standing + bug in a _calculate_tag_weight() method. - http://code.google.com/p/django-tagging/issues/detail?id=91 + When a programmer creates tag cloud using method util.calculate_cloud() + or Tag.objects.cloud_for_model() and sets distribution argument to + ``LOGARITHMIC'' (or leave it empty as it is default value) + _calculate_tag_weight() in some cases may return result which is greater + than max_weight - because of that Tag object (the one most frequently + used in model) will be missing argument ``font_size'' and throw + AttributeError exception. It happens because of the way a floating point + division is done in Python. - This issue has been reported on Google Code quite some time ago, and - although there has been a patch available for well over a year, the - patch just doesn't seem to get applied. Without this patch, many - websites written in Django will often crash when generating a tag cloud, - because the font_size field does not always get set, and this does seem - to happen quite a lot. + The proposed patch address this issue by returning ``max_weight'' in + case when result of computation is greater than it. - I am not sure why this patch has not been applied for so long, maybe the - upstream author will need to be contacted about this. + I'm attaching a testcase in a form of a django project. To use it you + must install python-django-tagging and then from project root execute + ``./manage.py test''. AssertionError will be thrown. After fixing this + issue test passes. - I have created a package myself with this patch applied in my own PPA - should anyone need it for the time being: - - https://launchpad.net/~robvdl/+archive/ppa + A link to upstream bugreport: http://code.google.com/p/django- + tagging/issues/detail?id=91 ** Attachment added: "testcase_367214.tgz" http://launchpadlibrarian.net/26012610/testcase_367214.tgz -- utils.calculate_cloud() can leave font_size unset for most frequent tag https://bugs.launchpad.net/bugs/367214 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
