This is an implementation of a tree structure for MongoMapper.
Install as gem
gem install ramdiv-mongo_mapper_acts_as_tree
Enable the tree functionality by declaring acts_as_tree on your model
class Category include MongoMapper::Document include MongoMapper::Acts::Tree key :name, String acts_as_tree end
The method accepts :parent_id_field, :path_field, :depth_field, :order, :search_class as a hash.
:parent_id_field, :path_field, :depth_field => override the default field names :order => control the order (format "_field-name_ _[asc|desc]_") :search_class => expects a Class that is a MongoMapper::Document to be used for search
Check test_tree.rb and test_search_class.rb for examples.
Use it. If you find any bugs, contact me (if possible with a test case) or patch it yourself (see next section).
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.
