dm-devise lets you use devise (github.com/plataformatec/devise) with DataMapper. The gem gives you the options of 2 ORM setups depending on what library you wish to use for validations:
Uses dm-validations. This involves a bit of monkey-patching, but you need to use this if you want auto-validations in any of your models.
Uses ActiveModel::Validations. Do not use if you require 'dm-validations' anywhere in your app (or include it in your Gemfile). Things will break. The advantage to this is ActiveModel's I18n support for error messages, and it uses the same validations lib as devise does by default.
dm-devise is intended for use with Rails 3 and devise 1.1. It may work with earlier versions, but it's not been tested (if you try, please let Jared Morgan (github.com/jm81) know how it goes.)
This README only covers dm-devise specifics. Make sure to read the devise README github.com/plataformatec/devise/blob/master/README.rdoc
Last tested against devise release: v1.1.1
Last tested against devise master: 2010-09-25, commit 2aa1d2f3b76ce87c087a010c02d78a1156ac8669
Add dm-devise and dm gems to your Gemfile. The following gems are required:
gem 'dm-core', '~> 1.0.2' gem 'dm-sqlite-adapter', '~> 1.0.2' # or your preferred adapter gem 'dm-serializer', '~> 1.0.2' gem 'dm-timestamps', '~> 1.0.2' gem 'dm-rails', '~> 1.0.3' gem 'dm-validations', '~> 1.0.2' # Do not include if using data_mapper_active_model gem 'dm-devise', '~> 1.1.0'
If you're using data_mapper_active_model do not include dm-validations in your Gemfile.
Run the generator:
rails generate devise:install
The generator will install an initializer which describes ALL Devise's configuration options and you MUST take a look at it. Make sure to specify either data_mapper (for using dm-validations) or data_mapper_active_model (ActiveModel::Validations) as the orm in the configuration file.
To add Devise to any of your models using the generator:
rails generate data_mapper:devise MODEL

Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
