# add in config/initializers/mime_types.rb
Mime::Type.register "text/markdown", :markdown
Problem
I have `map.resources :posts` and I want to be able to serve post bodies in markdown format. So I set up my `respond_to` block: ``` respond_to do |format| format.markdown { render :text => @post.body.to_s } end ``` But when I try to access `/posts/1234.markdown`, I get this error: ``` NameError (uninitialized constant Mime::MARKDOWN): app/controllers/posts_controller.rb:96:in `show' app/controllers/posts_controller.rb:79:in `show' ``` How do I add markdown as an acceptable format? Where can I see the list of acceptable formats?
