不能有两个同名url路径。
您必须正确重命名URL:

path('', views.ContentHome, name='homepage'),
path('seasons', views.ContentSeasons),
path('seasons/<slug:seasonpost_slug>', views.ContentSeason, name='season-detail'),
path('seasons/<slug:seasonpost_slug>/<slug:episodepost_slug>', views.ContentEpisode, name='episode-detail'),

在HTML模板中,不需要使用逗号分隔参数:

{% if previous_episode %}
        <span class="span__bootons-navigatiom"><a href="{% url 'episode-detail' previous_episode.seasonpost.slug previous_episode.slug %}" title="previous">previous</a></span>
{% endif %}
{% if next_episode %}
        <span class="span__bootons-navigatiom"><a href="{% url 'episode-detail' next_episode.seasonpost.slug next_episode.slug %}" title="next">next</a></span>
{% endif %}

根据错误消息,href中的next_episode.seasonpost.slug似乎为空:

{% if previous_episode %}
        <span class="span__bootons-navigatiom"><a href="{% url 'episode-detail' previous_episode.seasonpost.slug previous_episode.slug, %}" title="previous">previous</a></span>
        {% endif %}
        {% if next_episode %}
        <span class="span__bootons-navigatiom"><a href="{% url 'episode-detail' next_episode.seasonpost.slug next_episode.slug, %}" title="next">next</a></span>
        {% endif %}

从你的帖子看,如果模特剧集有一个外键字段,那么它是不可见的。

  • 字段seasonpost为空或不存在
  • 字段seasonpost.slug为空或不存在
    在以下注解后编辑:

该错误消息

"....with arguments '('', 'episode-1')' not found ..."

指示您使用url标记

{% url 'name' arg1 arg2 %}

有两个参数,第一个是''(空),第二个是'episode-1'。Django url标签不允许空参数...所以请看看为什么第一个参数(previous_episode.seasonpost.slugnext_episode.seasonpost.slug)是空的。在上面的原始答案中,我在结尾给出了一些提示,为什么它们可以是空的。
