Using I18n markdown strings in HAML - ruby-on-rails

Question

I have localised markdown strings in my language file, and I am looking for a cleaner way to do the following in HAML:
#text_for_something
:markdown
#{ t(:text_in_markown) }
Or, equivalently:
#text_for_something!= Maruku.new( t(:text_in_markown) ).to_html

Answer 1

I know this is not what you were thinking of but you could just add the following helper to helpers/application_helper.rb
def render_md(key)
Maruku.new( t(key) ).to_html
end
and then just use it in your HAML like this:
#text_for_something!= render_md :text_in_markown
Hope it helps.

Answer 2

I ended up doing something similar for the i18n of my Rails Tutorial sample app. Not sure if it matters, but I used RDiscount to render Markdown.
In summary, I file each i18n-ized markdown file under a controller/action directory under config/locales, and determine which page needs to be rendered in the controller. For example, in the case of a simple About page, here is where the :en markdown file is located here:
config/locales/static_pages/about/about.en.md
About Us
========
Some more markdown text...
The path to the file to be rendered gets determined in the controller and assigned to #page, then the file itself gets rendered out in the relevant HAML partial:
app/controllers/static_pages_controller.rb
class StaticPagesController < ApplicationController
before_filter :localized_page
def about
# ...
end
# ...
protected
def localized_page
locale = params[:locale]
#page = "#{Rails.root}/config/locales/#{controller_name}/"\
"#{action_name}/#{action_name}.#{locale}.md"
end
end
app/views/static_pages/about.html.haml
= render 'static_page', title: t('.about_us'), page: #page
app/views/static_pages/_static_page.html.haml
- provide(:title, title) if title
:markdown
#{render file: page}
