Mongoid Markdown Extension

Mongoid field extension that returns an object with to_html method returning the content converted from Markdown syntax to html. The Markdown conversion is done using the Redcarpet library.

Installation

Add this line to your application's Gemfile:

gem 'mongoid_markdown_extension'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mongoid_markdown_extension

Configuration

The defaults are as follows:

extensions = {
  autolink: true
  footnotes: true
  highlight: true
  space_after_headers: true
  strikethrough: true
  superscript: true
}

render_options = {}

These can be overwritten with an initializer, for example config/initializers/mongoid_markdown.rb:

MongoidMarkdownExtension::Markdown.configure do |c|
  c.extensions = { autolink: true }
  c.render_class = CustomRenderer
  c.render_options = { filter_html: true }
end

See Redcarpet documentation for available extensions and render options.

Usage

Add to a Mongoid model:

class MyModel
  include Mongoid::Document
  field :text, type: MongoidMarkdownExtension::Markdown
end

Use it:

my_model.text = "*foo*"

my_model.text.to_html # => <strong>foo</strong>
my_model.text.to_s # => *foo*
