NoReverseMatch Django错误多个URL相同的方法

Question

error message:

ExceptionType: NoReverseMatch
Exception Value: Reverse for 'darts.teams.views.expanded_details' with arguments '(u'RightFlights',)' and keyword arguments '{}' not found.

in the template:

<a href="{{ lib.url(expanded_details, team.name) }}" class="btn btn-cog">Expanded Details</a>

in urls.py

urlpatterns = patterns('darts.teams.views',
    url(r'^(?P<teamname>.*?)/expanded_details/$', 'team_details', {'expanded': True}, "expanded_details"),
    url(r'^(?P<teamname>.*?)/details/$', 'team_details', name="team_details"),

    url(r'^(?P<teamname>.*?)/add_player/$', 'team_add_player', name="team_add_player"),
    url(r'^(?P<teamname>.*?)/add_player/confirm/$', 'team_add_player',"team_add_player_confirm"),
)

The additional URLs in urls.py all render fine, but the 'expanded_details' one is throwing the error.

Why is this one different than the others? Am I missing something blatant?

update

The error says "Reverse for 'darts.teams.views.expanded_details' failed", but it should be 'darts.teams.views.team_details' or 'expanded_details' . The first form is the path to view, the latter is the name of the named URL.
You could check the value of expanded_details inside the templatetag to ensure it is resolved to one of the correct values above, or follow slackjake's suggestion: use 'expanded_details' (note the single quote) directly.

(?P<teamname>.*? is invalid, maybe you mean (?P<teamname>.*?) ?
Also, what does lib.url do?
