所以，我有一个应用程序，有电影制片厂，电影和剪辑。每个工作室都有一个相关的电影，每部电影都有相关的片段。此内容仅由网站管理员上传。现在，用户能够从电影中查看各种剪辑，并且每次用户观看剪辑时，都会创建“印象”。我正在使用印象派宝石来跟踪每个剪辑的视图。这与我的下一点有关。
在管理员后端我想让管理员选择一个剪辑并选择一个日期范围，然后当他们点击过滤器时，它将显示在该给定范围内查看剪辑的所有用户。
我以表格格式工作，但是，我无法显示实际电影或剪辑的链接，我能够用np显示指向Studio的链接。
我做错了什么？
<% if @impressions %>
<table>

<% @impressions.each do |impression| -%>
<% @clip = Clip.where(id: impression.impressionable_id).first %>

错误＃1 ：

我做错了什么？
谢谢！
修改：
Studio.rb：
class Studio < ActiveRecord::Base
# attr_accessible :name, :code, :active, :trackable
after_save ThinkingSphinx::RealTime.callback_for(:studio)
has_many :films, :dependent => :destroy
has_many :clips, :through => :films
end
Film.rb：
class Film < ActiveRecord::Base
after_save ThinkingSphinx::RealTime.callback_for(:film)
belongs_to :studio
has_many :clips, :dependent => :destroy
has_many :film_countries
has_many :countries, :through => :film_countries, :source => :fcountry
end
Clip.rb：
class Clip < ActiveRecord::Base
after_save ThinkingSphinx::RealTime.callback_for(:clip)
is_impressionable :counter_cache => true, :unique => :request_hash
the impressionist gem is tracking all of the views for us. And what do u want to render ?
a list of results, between the two dates of usofe rwhat of users who viewed the clip u selected
belongs_to :film
has_one :video, :dependent => :destroy
has_many :playlist_item
end

如果你看错了，他们会说：
缺少必需的密钥：[：id]
缺少必需的密钥：[：film_id]
所以问题是您的路由是嵌套的，并且您没有传递完整信息以形成正确的路由。试试这些链接：
<%= 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) %>
