AttributeError
'NoneType' object has no attribute 'year'
Exception Type: AttributeError
Exception Value: 'NoneType' object has no attribute 'year'
Exception Location: /usr/lib/python2.5/site-packages/django/contrib/admin/templatetags/admin_list.py in date_hierarchy, line 271
In the following, years is getting set to [None]. That seems to happen when there are null values in the date field, as best I can tell:
years = cl.query_set.dates(field_name, 'year')
return {
'show': True,
'choices': [{
'link': link({year_field: year.year}),
'title': year.year
} for year in years]
}
Local vars:
_[3] []
cl <django.contrib.admin.views.main.ChangeList object at 0x89c628c>
day_field 'date_paid__day'
day_lookup None
field_generic 'date_paid__'
field_name 'date_paid'
link <function <lambda> at 0x8b5af44>
month_day_format u'F j'
month_field 'date_paid__month'
month_lookup None
year None
year_field 'date_paid__year'
year_lookup None
year_month_format u'F Y'
years [None]
My temporary work around is to not use date_hierarchy in the admin ui.
