Я планировал использовать этот модуль (полный пример здесь 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
но, похоже, эти значения не достигают модели.
class Category < ActiveRecord::Base
include Name_and_key
has_many :tiles
validates_presence_of :name, :key
end
и
cat = Category.create do |c|
c.name = "cat"
end
ActiveRecord :: StatementInvalid: SQLite3 :: ConstraintException: Categories.name не может быть NULL: INSERT INTO "Categories" ("creation_at", "updated_at", "id") VALUES ('2010-08-15 23:20 : 43 ',' 2010-08-15 23:20:43 ', 980190962)
Является ли это правильным подходом вообще, если нет, то как это можно сделать? Если действительно, в чем моя ошибка?
Неудачный юнит-тест
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
конец
Какой-то след
