Ruby on Rails：如何在视图中显示“原始”erb标记？

[英]Ruby on Rails: How do you display “raw” erb tags in views?

原文 2013-09-18 21:15:10 4 2 ruby-on-rails/ ruby

For example, I want to display <%= @location.country %> in views to the user. 例如，我想在视图中向用户显示<%= @location.country %> 。 So if the user visits http://domain.com/tutorials/123 , he'll see <%= @location.country %> . 因此，如果用户访问http://domain.com/tutorials/123 ，他会看到<%= @location.country %> 。 That is, Rails doesn't process that portion. 也就是说，Rails不处理该部分。

I'm thinking something along the lines of <*= @location.country %> , but of course that doesn't work. 我正在考虑<*= @location.country %> ，但当然这不起作用。 Any ideas? 有任何想法吗？

你添加第二个％。

<%%= @location.country %>

You need to use html entities for the < ( < ) and > ( > ). 您需要为< （ < ）和> （ > ）使用html实体。 So something like <%= @location.country %> 所以类似于<%= @location.country %> will work. 将工作。
