链接时缺少必需的键
链接时缺少必需的键
提问于 2014-09-14 17:03:20
因此，我有一个应用程序，电影制片厂，电影和剪辑。每个工作室都有一个相关的电影，每个电影都有相关的剪辑。此内容仅由网站管理员上传。现在，用户可以观看来自电影的各种剪辑，每一次用户观看一个剪辑，都会产生“印象”。我使用印象派宝石跟踪每个剪辑的视图。这与我的下一个观点有关。
在管理后端，我希望允许管理员选择一个剪辑并选择一个日期范围，然后当他们单击filter时，它将显示在给定范围内查看该剪辑的所有用户。
我有一个表格格式的工作，然而，我不能显示一个链接到实际的电影或剪辑，我能够显示一个链接到工作室与np。
我做错了什么？

如果你看到自己的错误，他们会说：
缺少所需密钥：:id 缺少所需密钥：:film_id
因此，问题是您的路由是嵌套的，并且您没有传递完整的信息来形成正确的路由。尝试以下链接：
<%= link_to @clip.film.name, saas_admin_studio_film_path(@clip.film.studio, @clip.film) %>
<%= link_to @clip.name, saas_admin_studio_film_clips_path(@clip.film.studio ,@clip.film) %>页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
