2.0 (uber-alpha)

Comatose is a micro CMS designed for being embedded into existing Rails applications.

It's intended for simple CMS support. Comatose supports

* Nested pages
* Versioning
* Page markup in Textile, Markdown, RDoc, or easily add your own 
* Page processing through Liquid or ERb
* Generators for easy installation/migration
* Completely self-contained within plugin folder

It's meant to be lean, mean, easily embedded, and easy to re-skin for existing applications. If you need something more, I would recommend looking into Radiant.

For more information, see the 'Getting Started' guide:


* Rails 2+ (2.1)
* <tt>acts_as_list</tt> and <tt>acts_as_tree</tt> plugins are required

Development Notes

NOTE: This is an active branch of Comatose that is built specifically for Rails 2.1.

       I will *probably* remove any legacy support.

* Make comatose fully self-contained, which means removing acts_as_(tree|list)
* Move to gem plugin
* Comatose.configure needs to be an initializer (update docs)
* Go through bugs on 1x branch from google code and ensure they are fixed
* Give access to all the default rails helpers to Comatose Pages by default?


Note: See the 'Upgrading' section if you already have an older version of

      the comatose plugin installed.

$ ./script/plugin source
$ ./script/plugin install comatose
$ ./script/generate comatose_migration
$ rake migrate

Open your routes.rb and add the comatose root route at the bottom:

map.comatose_root ''

That's it, you're ready to go! You should be able to browse to and start adding pages to your CMS. Browsing to will render your comatose pages if routing doesn't match any of your controllers.


NOTE: This is an experimental 2.0 branch, so upgrading is possible at

the moment, but these instructions may not work for much longer.

If you are upgrading from an older version of Comatose (version 0.3, 0.4, 0.5, or 0.6), then you will need to re-install the comatose plugin and run:

$ ./script/plugin remove comatose
$ ./script/plugin install comatose
$ ./script/generate comatose_migration --upgrade --from=VERSION
$ rake migrate

Note: Be sure to set the --from parameter to the version of Comatose you last had installed. Also, you only need to first two digits, including the dot, of the version you are upgrading from. For example, if you're upgrading from version 0.6.9 you can use:

$ ./script/generate comatose_migration --upgrade --from=0.6

This will create the upgrade migration(s) for you. It just adds the new fields, so you can keep the original migration comatose created.


You configure Comatose in your `config/environment.rb` file. Here is an example configuration block:

Comatose.configure do |config| # Sets the text in the Admin UI's title area config.admin_title = “Site Content” config.admin_sub_title = “Content for the rest of us…” end

Here's an example that uses the AuthentiationSystem as generated by the restful_authentication plugin:

Comatose.configure do |config| # Includes AuthenticationSystem in the ComatoseController config.includes << :authenticated_system

# admin config.admin_title = “Comatose - TESTING” config.admin_sub_title = “Content for the rest of us…” # Includes AuthenticationSystem in the ComatoseAdminController config.admin_includes << :authenticated_system # Calls :login_required as a before_filter config.admin_authorization = :login_required # Returns the author name (login, in this case) for the current user config.admin_get_author do current_user.login end end
