Redmine

I'm debugging the advance roadmap plugin (http://ociotec.com/redmine/projects/advanced-roadmap). It is trying to add has_many to ProjectModel. I've never done that myself and the error messages aren't helpful so guidance is useful.

It When I do a migrate I get:

aliasing.rb:33:in `alias_method': undefined method `roadmap' for class `ProjectsController' (NameError)
    from /home/gap/redmine/vendor/rails/activesupport/lib/active_support/core_ext/module/aliasing.rb:33:in `alias_method_chain'
    from /home/gap/redmine/vendor/plugins/advanced_roadmap/lib/projects_controller_patch.rb:9:in `included'

lib/projects_controller_patch.rb is adding has_many :milestones to Project. It looks like:

require_dependency "projects_controller" 

module ProjectPatch
  def self.included(base)
    base.class_eval do
      has_many :milestones
    end
  end
end

It is called from init.rb

...
Dispatcher.to_prepare do
  begin
    require_dependency "application" 
  rescue LoadError
    require_dependency "application_controller" 
  end

  Issue.send(:include, IssuePatch)
  # Call ProjectPatch
  Project.send(:include, ProjectPatch)
  ProjectsController.send(:include, ProjectsControllerPatch)
  ProjectsHelper.send(:include, ProjectsHelperPatch)
  Redmine::I18n.send(:include, RedmineI18nPatch)
  Version.send(:include, VersionPatch)
end
