How to render html content with erb tags in rails?

问题

I'm writing simple cms engine, and having a problem with dynamic content rendering, for example I prepare some page content with erb tags and helpers, how I can evaluate them in my view? Thanks.

回答1:

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.

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"
