Ruby on rails 如何创建要与render一起使用的类'；部分'；，：收集

我尝试创建包含枚举的ruby类 所以在DE视图中，我尝试使用render类，该类具有每个方法，并且应该返回为特定内容id构建的对象

下面是使用此代码的视图一些文件.haml

.
.
.
%table{:border => "0"}
  %thead
    %tr
      %td Files
      %td Views
      %td Comments
      %td Likes 
  %tbody
    - render 'content_stats_row', :collection => @graphs.content_stats_table, :as => :row
.
.
.

这是我的@graphs

module FusionGraphs
  class ContentStatsTable
    include Enumerable

    def initialize(content_ids, start_date, end_date)
      @content_ids, @start_date, @end_date = content_ids, start_date, end_date 
    end

    def summarized_content
      @summarized_content ||= Hash[ Content.where(:id => @content_ids).value_of(:id, :name) ]
    end

    def summarized_comments
      @summarized_comments ||= Comment.where(:content_id => @content_ids)
                                  .where('date(created_at) between ? and ? ', @start_date, @end_date)
                                  .group(:content_id)
                                  .count
    end

    def summarized_views
      @summarized_views ||= View.where(:viewable_type => 'Content', :viewable_id => @content_ids)
                            .where('date(created_at) between ? and ? ', @start_date, @end_date)
                            .group(:viewable_id)
                            .count

    end

    def summarized_likes
      @summarized_likes ||= Like.where(:content_id => @content_ids)
                            .where('date(created_at) between ? and ? ', @start_date, @end_date)
                            .group(:content_id)
                            .count
    end

    def each
      @rows ||= @content_ids.map do |content_id|
              OpenStruct.new( :content_name => summarized_content[content_id],
                              :views => summarized_views[content_id] || 0,
                              :comments => summarized_comments[content_id] || 0,
                              :likes => summarized_likes[content_id] || 0
                            )
             end
    @rows.each {|row| yield row }
    end

  end
end

我无法从**呈现'content\u stats\u row'，：collection=>graphs.content\u stats\u table，：as=>：row获得结果** 它不起作用

我做错了什么？

在haml视图文件中，您在渲染之前放置了（-）连字符，它应该是（=）相等的。

将

-render

替换为

=render

谢谢。我觉得自己像个白痴：(
