每个相关页面都有效，但只有索引页面可以获取
NoReverseMatch位于/ 找不到带有关键字参数'{'slug'：''}'的'series_detail'。尝试了1个模式：['（？P [^ /] +）\ / $']
我真的不明白。每个页面的URL，包括series_detail的作品。...
问题是这一行： {{all_episode.series}}
这是我的代码（任何帮助将不胜感激）

答案 0 :(得分：1)
您应该在series_pg视图中检查对象是否存在。它给出Series.DoesNotExist。因此，如果找不到，请显示404页面。
from django.shortcuts import get_object_or_404
# ...
def series_pg(request, slug):
series = get_object_or_404(Series, slug=slug)
season = Season.objects.filter(series=series).order_by("season_nr")
episode = Episode.objects.filter(series=series).order_by("date")
content_dict = {
'series':series,
'season':season,
'episode':episode,
}
return render(request, 'series.html', content_dict)
