Ruby on rails 标记范围面太阳黑子solr的行

我在rails应用程序中使用sunspot solr来处理搜索，并且我已经设置了一个facet来允许搜索价格范围。如何创建用于视图中行值的标签。这建议使用条件语句，但我不确定我将如何做到这一点

因此，例如，代替如下所示的值：

0.0..75.0
75.0..150.0
150.0..225.0
225.0..300.0

等等。。我想将它们显示为：

$0 - $75
$75 - $150
$150 - $225
$225 - $300

有人能帮我吗？谢谢

<% end %>

row.value，：search=>params[：listings]>

这只是一个正则表达式替换的问题吗

试试这个：

new_string = old_string.gsub(/\.0\.\./,"$ - ").gsub(/\.0/,"$")
# old_string = "0.0..75.0"
# new_string = "0$ - 75$"

这可能意味着在您的代码中

    <%= link_to (row.value).to_s.gsub(/\.0\.\./,"$ - ").gsub(/\.0/,"$"), 
                :price_range => row.value, :search => params[:listings] %>

row.value，：search=>params[：listings]>

它给了我这个错误

0.0..75.0:Range的未定义方法“gsub”

是的，就是它。谢谢
