How can I automatically render partials using markdown in Rails 3?

Question

I want to have some of my partials as markdown snippets. What is the easiest way to render them using the standard rails erb templating?

Ideally, I\'d like to do so

Piling on the solutions already presented, this is an interpolation-ary way in Rails 3 to render a pure Markdown file in a view from a partial without unnecessary indentation using Haml's :markdown filter and the RDiscount gem. The only catch is that your Markdown file is a Haml file, but that shouldn't matter for someone like a copy person.

In Gemfile:

gem 'rdiscount'

In app/views/my_page.html.haml

:markdown
  #{render 'my_partial', language: 'Markdown!'}

In app/views/_my_partial.html.haml

My awesome view
===============

Look, I can **use** #{language}!

If you didn't need the :language variable passed in to the markdown file, you could do away altogether with your Markdown being a Haml file:

In app/views/my_page.html.haml

:markdown
  #{render 'my_partial.md'}

In app/views/_my_partial.md

My awesome view
===============

Sorry, cannot **use** #{language} here!

Don't like those pesky underscores on your Markdown files?

In app/views/my_page.html.haml

:markdown
  #{render file: 'my_markdown.md'}

In app/views/my_markdown.md

My awesome view
===============

Sorry, cannot **use** #{language} here!
