Rendering markdown text in Rails 3

I want to convert markdown to html. In my views I have markdown(some_text_variable) but I get the error undefined method markdown.

I added require 'BlueCoth' to enviroment.rb and 开发者_如何转开发I installed the BlueCloth gem. Can anybody help me?

In your Gemfile:

gem 'bluecloth'  

and don't forget to run

bundle install

when you need to convert markdown to html, simply use:

markdown = BlueCloth.new(some_text_variable).to_html

You can use it in a view:

<%= markdown.html_safe %>

You can use RDiscount https://github.com/rtomayko/rdiscount

The #markdown helper was removed in Rails 3.

You can copy & paste the code from the commit or use a third party Gem, like formatize. You will also have to include the required BlueCloth/RedCloth/etc gem in your Gemfile.

I'd recommend against bluecloth as it doesn't look like it's being upkept that well.

Best thing I've found out there as of now (summer 2013) is the Redcarpet gem: https://github.com/vmg/redcarpet

Try adding the following to your environment.rb instead of the require:

config.gem 'BlueCloth', :lib => 'bluecloth'

In Rails 3, this would be in the Gemfile:

gem 'bluecloth'

The gem is called BlueCloth, but the .rb file that gets required is all lowercase.

Make sure you restart rails after adding the config.gem line.
