Tiny plugin for MongoMapper to add multi-parameter attributes

Based on Rails & gist by @bitzesty found at:


Either load it into all models, or individual models:

# add to all models

# add to a specific model
plugin MongoMapper::Plugins::MultiParameterAttributes

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 in another branch so I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.


$ gem install mm-multi-parameter-attributes
