python - URLconf 不适用于类似的 URL

Question

这是我的 URLconf:

urlpatterns = patterns('',
    url(r'^new_player/$', new_player, name="new_player"),
    url(r'^new_player/player_added/$', player_added, name="player_added"),
    url(r'^(\d+)/new_avatar/$', new_avatar, name='new_avatar' ),
    url(r'^(?P<user_name>[-\w]+)/new_game/$', new_game, name='new_game' ),
    url(r'^$', 'django.views.generic.list_detail.object_list', { 'queryset': Player.objects.all(),'extra_context': {'players' : Player.objects.annotate(total_amount_won=Sum('avatar__games__profit'))}}, 'stakeme_player_list'),
    url(r'^(?P<real_name>[\w|\W]+)/', usernames_by_player),
    url(r'^(?P<user_name>[\w|\W]+)/', avatars_by_username),
)

如上所述，url(r'^(?P<real_name>[\w|\W]+)/', usernames_by_player),将显示其关联的模板，但是 url(r'^(?P<user_name>[\w|\W]+)/', avatars_by_username),将 404。

如果我颠倒最后两个 URL 的顺序，则 usernames_by_player 将显示 404而不是avatars_by_username

我可以看到，由于相似的 URL 模式，这可能会导致问题，但有人可以解释一下原因以及如何解决吗？

Answer 1

这些 URL 会按照您定义的顺序进行查找。所以这一行 url(r'^(?P<real_name>[\w|\W]+)/', usernames_by_player)获取请求 url 中的所有输入。您应该区分这些网址，例如:

url(r'^realname/(?P<real_name>[\w|\W]+)/', usernames_by_player),
url(r'^username/(?P<user_name>[\w|\W]+)/', avatars_by_username),

希望这能引导我们走向正确的方向。
