このモジュールを使用する予定でした (完全な例はこちらhttp://pastie.org/1098444 )

puts "Name_and_key was referenced."

module Name_and_key

  def normalize(s)
    s.mb_chars.normalize(:kd).gsub(/[^\-x00-\x7F]/n, '').to_s
  end

  def name=(name)
    self[:name] = name
    self[:key] = normalize(name).downcase
  end

  def name
    self[:name]
  end

  def key=(key)
    self[:key] = normalize(key).downcase
  end

  def key
    self[:key]
  end

end

しかし、これらの値はモデルに到達していないようです。

 class Category < ActiveRecord::Base
  include Name_and_key

  has_many :tiles
  validates_presence_of :name, :key
end

と

cat = Category.create do |c|
 c.name = "cat"
end

ActiveRecord::StatementInvalid: SQLite3::ConstraintException: categories.name は NULL にできません: INSERT INTO "categories" ("created_at", "updated_at", "id") VALUES ('2010-08-15 23:20:43' 、「2010-08-15 23:20:43」、980190962)

どうすればこれを行うことができなければ、これはまったく有効なアプローチですか? もしそうなら、私の間違いは何ですか？

単体テストの失敗

test "can be created" do
cat = Category.create do |c|
  c.name = "cat"
end
tile = Tile.create do |t|
  t.name = "test"
  t.category = cat
end
assert tile.save

終わり

若干の痕跡

validates_presence_of :nameルビー側でこれらのエラーをキャプチャするために追加することをお勧めします。アプリは、一見有効なオブジェクトをDBに保存しようとします。名前はNULLで、ルビー側が許可します。ここでNOTNULLを設定したため、DBが爆発しました。これは、そこに保存しているものが気に入らないためです。
