ruby-on-rails - Rails 的新记录？如果事务回滚则不重置(为真)

Question

因此在 Rspec 中进行以下测试:

require 'spec_helper'
describe Author do
  self.use_transactional_fixtures = false

  after(:each) do
    Author.destroy_all
  end

  it "should behave normal when using transactions" do
    my_author = nil
    begin
      Author.transaction do
        my_author = Author.new(:name => "My Name")
        my_author.new_record?.should be_true
        my_author.save!
        raise "some exception"
      end
    rescue
    end
    Author.count.should == 0
    my_author.new_record?.should be_true
  end
end

最后一行:

my_author.new_record?.should be_true

给出:

'Author should behave normal when using transactions' FAILED
expected true, got false

至少当你回滚一些记录创建时，我希望它能完全回滚，所以重置 new_record？还有身份证。我在这里错过了什么吗？这是故意的吗？我正在使用 Rails 2.3.5

Delph，这是 Rails 中的一个错误。它应该重置 id 和 new_record，但它没有。
