由于某些原因我还没想到，我收到以下错误：

现在，一切都运转正常。输入字段工作正常，并发布到数据库中。重定向到另一个模板直到今天仍然有效。它看起来问题出现在我form_chapter_marks.html <a class="btn btn-primary box-shadow--6dp" href="{% url 'podfunnel:episodeshowlinks' %}" role="button"><i class="fa fa-chevron-right pull-right" aria-hidden="true"></i>&nbsp Next</a>下的url模板中，但我不知道为什么错误现在显示在我之前没有遇到问题时。

在此感谢一些帮助。

我不确定为什么你展示了所有剩下的代码; URL和模板片段就足够了。

在您引用的片段中，您显示您正在呼叫{% url 'podfunnel:episodeshowlinks' %}。但是您的网址 - 以及错误消息 - 显示名称为episodeshowlinks的唯一模式正在预期参数：production_id。您需要将其传递给url标记，以便它知道要生成的URL。

请注意，您的网址通常很破旧;我无法理解为什么你有两个带有前缀“episodeshowlinks /”的URL，一个带有production_id，一个带有show_id，第二个带有名字“episodeshowlinks_edit”。 Django无法区分它们，因此Django将始终调用第一个，并且永远不会在kwargs中获得“showlink_id”。
