ERROR: Invalid Renderer instance given in ruby on rails

Question

I'm newbie on ruby on rails application, from last few days I'm suffering about Markdown with Redcarpet issue, I following this tutorial , I'm don't understanding why showing this error.

Invalid Renderer instance given

This is my helper:

def markdown(text)
  #Redcarpet.new(text).to_html.html_safe
  Redcarpet::Markdown.new(text).to_html
end

My View:

 <%= markdown(@details.post_details) %>

Gemfile:

gem 'redcarpet'

That would help me a lot, please.

Answer 1

I think should work, after following this:

  <%= markdown(@details.post_details) %>

Should try

 <%= raw @details.post_details %>

Work for me
