再開発メモ003

引っ越し

唐突だが、ここを捨ててはてなブログに移行することにした。
記事の引き継ぎはせず完全に仕切りなおすので、MOE3 の再開発メモは３桁どころか３回で終了。我ながらぐうの音も出ない三日坊主ぶり。

まあどうせ向こうでもやること自体は何も変わらないけど、ひとまず書いた分だけ投下したらこっちは放置しま。

Province モデル

スキーマ。

  create_table "provinces", force: true do |t|
    t.string   "code"
    t.string   "fullname"
    t.boolean  "supplycenter", default: false
    t.integer  "homepower_id"
    t.string   "port"
    t.string   "type"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

モデル。Province#shortname もさっくり実装。

class Province < ActiveRecord::Base
  belongs_to :homepower, class_name:'Power'

  def shortname
    code.capitalize
  end
end

そして Province の派生クラス群。
Land と Sea は今のところ空っぽ。Coast は港の扱いがあるので #shortname をオーバーライド。

class Land < Province
end

class Sea < Province
end

class Coast < Province
  def shortname
    result = super
    result += "(%s)"%[port.upcase] if port
    result
  end
end

以上を踏まえて seeds.rb も書き直し。
spec_helper.rb をいじってテストの時も読み込ませるので、テストを実行する度にマスタデータが増えないように最初に delete_all している。
ただし id はリセットされないのでテスト環境専用の扱い。開発環境ではおとなしく rake db:reset しとけ。
DB に依存しない id のリセット方法があったら知りたいけどあまり役には立たないか。

## Power
Power.delete_all
a = Power.create symbol:'A', name:'Austria', genitive:'Austrian'
e = Power.create symbol:'E', name:'England', genitive:'English'
f = Power.create symbol:'F', name:'France',  genitive:'French'
g = Power.create symbol:'G', name:'Germany', genitive:'German'
i = Power.create symbol:'I', name:'Italy',   genitive:'Italian'
r = Power.create symbol:'R', name:'Russia',  genitive:'Russian'
t = Power.create symbol:'T', name:'Turky',   genitive:'Turkish'
Power.create symbol:'X', name:'Master'

うむ。相変わらずシングルクォートとダブルクォートの混在が見苦しい。後でダブルに統一しておこう。

次は何をするか。
Province を作った流れで「Adjacency（隣接情報）」に手を出すのもいいけど、これが必要になるのはずっと後のはず。なのでやっぱり「Order」かな。
