Redmine is a flexible project management web application written using Ruby on Rails framework.
More details can be found at www.redmine.org
This fork is supposed to be Rails 3 compatible.
Currently not working:
The error_messages_for call doesn't work, there seems to be an issue with dynamic_form;
Mail notifications. The message is built, but calling deliver raises exceptions so it's disabled (Mailer needs to be rewritten);
Custom fields validations is not working properly (Query needs to be rewritten);
