Redmine

I'm just looking for some pointers (articles, tutorials, or general tips) for creating a plugin which uses this redmine hook: model_changeset_scan_commit_for_issue_ids_pre_issue_update

I'm trying to modify the ticket that's "fixed" on a repository commit to change the author. I already have the working code that I can use if I patch the core to do what I want. So now I'm trying to pull it out into a plugin (per Eric's suggestion).

So I think I'm on the right, track, but if anyone can help me out, I'd appreciate it.

init.rb

require 'redmine'
require 'dispatcher'

Dispatcher.to_prepare :redmine_reassign_original_author do
  require_dependency 'issue'

  unless Issue.included_modules.include? RedmineReassignOriginalAuthor::IssuePatch
    Issue.send(:include, RedmineReassignOriginalAuthor::IssuePatch)
  end
end

Redmine::Plugin.register :redmine_reassign_original_author do
  name 'Reassign to Original Author'
  author 'Brett Patterson'
  description 'Adds extra functionality to the "fixes" keyword to reassign that issue to its original author'
  version '0.0.1'

  requires_redmine :version_or_higher => '1.0.2'
end

lib/redmine_reassign_original_author/issue_patch.rb

module RedmineReassignOriginalAuthor
  module IssuePatch
    def self.included(base)
      base.extend(ClassMethods)
      base.send(:include, InstanceMethods)
      base.class_eval do
        unloadable

        model_changeset_scan_commit_for_issue_ids_pre_issue_update :reassign_to_original_author
      end
    end

    module ClassMethods
    end

    module InstanceMethods
      def reassign_to_original_author
        ReassignOriginalAuthorIssue.reassign_author(self)
      end
    end
  end
end

app/models/reassign_original_author_issue.rb

class ReassignOriginalAuthorIssue < ActiveRecord::Base
  def self.reassign_author(issue)
    return true if issue.nil?
  end
end

I know I have probably a bunch of missteps in there, but some direction would be great. Thanks!
