Redmineプラグイン開発 – 日付指定で時間コストを表示 – 旅と子育てとアジャイルコーチのブログ「世界」

NetBeans6.5で作ります。
ソースはGoogle Codeを参照のこと。
redmineは「c:\fujihara\Ruby\redmine-0.8.0」にあって、WEBrickを使って動かす。

ValueObject

表示用データを格納するValueObjectをplugin_root/app/libに作成。
Main

 # To change this template, choose Tools | Templates
# and open the template in the editor.
class TimeReportMainVO
TRACKER_SUM_STRING = "合計"
def initialize
@project_name = ""
#FIXME
@trackers = Hash.new()
all_trackers = Tracker.find(:all)
all_trackers.each do |tracker|
@trackers[tracker.name] = TimeReportDetailVO.new()
end
@trackers[TRACKER_SUM_STRING] = TimeReportDetailVO.new()
end
def get_tracker(name)
return trackers[name]
end
def put_tracker(name, value)
trackers[name] = value
end
attr_accessor :project_name, :trackers
end

Main has Detailになっている。
Detail

 # To change this template, choose Tools | Templates
# and open the template in the editor.
class TimeReportDetailVO
def initialize
@estimated_hours = 0.0
@actual_performances = 0.0
@percentages = 0.0
end
attr_accessor :estimated_hours, :actual_performances, :percentages
end

Controller

ControllerではVOに計算したデータを格納する。

View

グラフで表示するためにHTML5.JPのライブラリを利用。
plugin_root/app/assets/javascripts/html5jpにライブラリを配置した。
