Thanks - that makes sense. I might have even done that previously, but
I am still getting errors - I must have mistakenly attributed the
error.

New error is:
Exception Type: NoReverseMatch
Exception Value: Reverse for 'student-reports' with arguments '()' and
keyword arguments '{'year': 2013}' not found.

but my urls.py includes these lines:
url(r'^students/reports/$', student_reports, name='student_reports'),
url(r'^students/reports/(?P<year>\d{4})/$', student_reports,
name='student_reports'),


and the view:
def student_reports(request, year=None):
year = year or datetime.date.today().year
...

What am I doing wrong now?

Cheers
L.
