Calling ERB without Rails: undefined method 'raw'

Question

I am using the ERB engine to generate an offline HTML version of a page of my Rails website. The page shows great when shown by Rails, but I have trouble generating with ERB by myself (despite using the same ERB template).

First I was getting the error undefined method 't' and I solved it by replacing all <%=t(...)%> calls with <%=I18n.translate(...)%>.

Now I get undefined method 'raw'. Should I replace all <%=raw(...)%> calls with something else? If yes, what?

Answer 1

raw is defined as helper in actionpack/action_view library so that without rails you can't use it. But ERB templating shows its output without any escaping:

require 'erb'
@person_name = "<script>name</script>"
ERB.new("<%= @person_name %>").result # => "<script>name</script>" 

And because of this for purpose of escaping there is ERB::Util#html_escape method

include ERB::Util
ERB.new("<%= h @person_name %>").result # => "&lt;script&gt;name&lt;/script&gt;"
