Erb 和 Sinatra 在 ruby 中

发布于 2024-08-27 08:22:51 字数 499 浏览 5 评论 0原文

所以我有一个使用 sinatra 构建的网络服务器，其主要内容如下：

set :variable,"value"
get '/' do
  erb :index
end

当然，views/index.erb 中的模板如下所示：

<html>
<!-- etc -->
  <ul>
  <% my_array.each do |thing| %>
  <%="Something: #{thing}, variable from sinatra: #{settings.variable}"%>
  <% end %>
  </ul>
</html>

如果您尝试运行像这样的代码，您会注意到您无法从 erb 模板内部访问 sinatra 的设置变量。有什么想法可以在保持简单性的同时实现这一目标吗？

提前致谢！

So I have a webserver I've built using sinatra, the meat of which goes like this:

set :variable,"value"
get '/' do
  erb :index
end

And, of course, the template in views/index.erb which looks something like this:

<html>
<!-- etc -->
  <ul>
  <% my_array.each do |thing| %>
  <%="Something: #{thing}, variable from sinatra: #{settings.variable}"%>
  <% end %>
  </ul>
</html>

If you try running code like this you'll notice that you can't access sinatra's settings variable from inside erb templates. Any ideas how I can achieve this while keeping its simplicity?

Thanks in advance!
