函数 get_absolute_url() 中 url reverse() 出错
无法反转每个模型（serial_slug）中的 url，但 url 本身存在！
这是主 url.py
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^series/', include("serials.urls", namespace='series')),
url(r'^', include("serials.urls", namespace='homeview')),
]
这是我的应用程序中的 urls.py
from django.conf.urls import include, url
from .views import homeview, post_of_serial, post_of_season, post_of_serie
urlpatterns = [
url(r'^$', homeview, name='homeview'), # /series/
url(r'^(?P<serial_slug>[\w-]+)/$', post_of_serial, name='post_of_serial'), # /series/Prison_Break/
url(r'^(?P<serial_slug>[\w-]+)/(?P<season_slug>[\w-]+)/$', post_of_season, name='post_of_season'), # /series/Prison_Break/season_5/
url(r'^(?P<serial_slug>[\w-]+)/(?P<season_slug>[\w-]+)/(?P<series_slug>[\w-]+)/$', post_of_serie, name='post_of_serie'), # /series/Prison_Break/season_5/2/
]
这是 models.py

使用参数“()”和关键字参数反转“post_of_serial”
'{'serial_slug': ''}' 未找到。尝试了 1 个模式：
['系列/(?P[\w-]+)/$']
（lookup_view_s、args、kwargs、len（模式）、模式）
django.urls.exceptions.NoReverseMatch：“post_of_serial”的反向
使用参数 '()' 和关键字参数 '{'serial_slug': ''}' 不
成立。尝试了 1 个模式：['series/(?P[\w-]+)/$']
