推荐答案

如果我对您的理解正确，则希望在运行时将包含ERB标记的代码段存储在某个位置在您的Rails应用程序的真实模板中评估它们。

if i understand you correctly, you want to store snippets that contain ERB markup somewhere and at runtime evaluate them in your real templates of your rails app.

在这种情况下，我认为您将必须手动调用ERB。这并不难：

in this case, i think you will have to invoke ERB by hand. this is not really hard:

require 'erb'
name = "Rasmus"
template_string = "My name is <%= name %>"
template = ERB.new template_string
puts template.result # prints "My name is Rasmus"
