帮助红宝石与HTML标签

Question

我想写一个帮手来创建一个可折叠的Grop。 我转换

<div class="panel panel-default"> 
<div class="panel-heading" role="tab" id="headingOne"> 
    <h4 class="panel-title"> 
    <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne"> 
     Collapsible Group Item #1 
    </a> 
    </h4> 
</div> 
<div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne"> 
    <div class="panel-body"> 
    text to answer 
    </div> 
</div> 

要

def faqbox(question, answer, number) 
open :div, :class => "panel panel-default" do 
    open :div, :class => "panel-heading", :role => "tab", :id => "heading#{number}" do 
    open :h4, :class => "panel-title" do 
     open :a, :role => "button", :data-toggle => "collapse", :data-parent => "#accordion", :href => "#collapseOne", :aria-expanded => "true", :aria-controls => "collapse#{number}" do 
     "#{question}" 
     end 
    end 
    end 
end 
open :div, :id => "collapse#{number}", :class => "panel-collapse collapse in", :role => "tabpanel", :aria-labelledby => "heading#{number}" do 
    open :div, :class => "panel-body" do 
    "#{answer}" 
    end 
end 
end 

但

我使用的是给我 “在/获取的帮助 符号的隐式转换为字符串类型错误”红宝石与中间人。我做什么？

请考虑使用部分而不是巨大的嵌套open

# _faqbox.html.erb 

<% heading = "heading#{number}"%> 
<% collapse ="collapse#{number}" %> 

<div class="panel panel-default"> 
    <div class="panel-heading" role="tab" id=<%= heading %>> 
    <h4 class="panel-title"> 
     <a role="button" data-toggle="collapse" data-parent="#accordion" href="#<%= collapse %>" aria-expanded="true" aria-controls="<%= collapse %>"> 
     <%= question %> 
     </a> 
    </h4> 
    </div> 

    <div id="<%= collapse %>" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne"> 
    <div class="panel-body"> 
     <%= answer %> 
    </div> 
    </div> 
</div> 


# some view 
<%= render partial: "faqbox", locals: {question: "foo", answer: "bar", number: 3} %> 

结果
