Practical Django Projectsという本で演習を行うと、問題が発生します。記事の詳細についてURLをクリックすると、エラーが返されます。

ここで見るために間違ったデータが渡されstrptimeています：

>>> time.strptime('2012dec04','%Y%b%d')
time.struct_time(tm_year=2012, tm_mon=12, tm_mday=4, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=1, tm_yday=339, tm_isdst=-1)
>>> time.strptime('2012/dec/04/test22/dec04','%Y%b%d')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_strptime.py", line 454, in _strptime_time
    return _strptime(data_string, format)[0]
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_strptime.py", line 325, in _strptime
    (data_string, format))
ValueError: time data '2012/dec/04/test22/dec04' does not match format '%Y%b%d'

その理由は、最初のグループが閉じられていないためです。

# yours
url(r'^weblog/(?P<year>\d{4}/(?P<month>\w{3})/(P<day>\d{2})/(P<slug>[-\w]+)/$)',"blogCategory.views.entry_detail"),

# change to
url(r'^weblog/(?P<year>\d{4})/(?P<month>\w{3})/(P<day>\d{2})/(P<slug>[-\w]+)/$',"blogCategory.views.entry_detail"),

$最初のグループは、最初のグループの前ではなく、周りに閉じていました/
