为什么这段 HTML 代码被呈现为一个巨大的字符串而不是被评估的代码？

部分代码：

<div class ="vote_updated">
    <p><%= event.actor %> <% case event.subject.value
        when 1
            puts " upvoted"
        when -1
            puts " downvoted"
        when 0
            puts " removed a vote from"  
        end %> a song. </p>
    <div class="video_div">
        <%= render 'videos/video', :video => event.secondary_subject %>
    </div>
</div>

被渲染为一个大字符串，而不是从正在评估的嵌入式 ruby 中生成的 HTML 代码。

这是渲染部分的代码：

<div id="feed_div">
    <%= render_timeline current_user.recent_events %>
</div>

这是 application_helper.rb 中的 render_timeline 方法：

def timeline(events)
  events.map do |event|
    render(:partial => "timeline_events/#{event.event_type}", :locals => {:event => event})
 end.join
end

This code in a partial:

<div class ="vote_updated">
    <p><%= event.actor %> <% case event.subject.value
        when 1
            puts " upvoted"
        when -1
            puts " downvoted"
        when 0
            puts " removed a vote from"  
        end %> a song. </p>
    <div class="video_div">
        <%= render 'videos/video', :video => event.secondary_subject %>
    </div>
</div>

is being rendered as one big string instead of the resulting HTML code from the embedded ruby being evaluated.

This is the code that renders the partial:

<div id="feed_div">
    <%= render_timeline current_user.recent_events %>
</div>

and this is the render_timeline method in application_helper.rb:

def timeline(events)
  events.map do |event|
    render(:partial => "timeline_events/#{event.event_type}", :locals => {:event => event})
 end.join
end

可能是您在 timeline 中对 .join 的调用将字符串标记为不安全 - 也许尝试将其更改为：

def timeline(events)
  events.map do |event|
    render(:partial => "timeline_events/#{event.event_type}", :locals => {:event => event})
 end.join.html_safe
end

看看是否有帮助:-)

It might be that your call to .join in timeline is marking the string as unsafe - maybe try altering it to:

def timeline(events)
  events.map do |event|
    render(:partial => "timeline_events/#{event.event_type}", :locals => {:event => event})
 end.join.html_safe
end

and see if that helps :-)
