Yet another tree plugin for MongoMapper, uses an array of reference numbers. Useful when the leaf/branch numbers are meaningful, so you don't have to separately maintain them.
Load it into a model:
Then call referenced_tree to configure it
referenced_tree :scope => :account_id
Available options are:
:scope - scope to a specific field (default - nil)
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-referenced-tree
