Ruby on Rails 刚刚发布了 2.3.6: 该版本包含六个月以来的 bug 修复,一小些新特性,以及一个到 Rails 3 的桥接。同时该版本废弃了一些无用的功能,而这些功能将于 Rails 3 中被删除。

详细的改进内容:

Action Pack

  • Upgrade Rack from 1.0.1 to 1.1.0.
  • XSS prevention: update to match Rails 3 and move to the official plugin at http://github.com/rails/rails_xss.
  • Cookies: convenient cookie jar add-ons to set permanent or signed cookies, or both at once: cookies.permanent.signed[:remember_me] = current_user.id. Read more.
  • Flash: promote alert and notice, the most common flash keys in many apps, to self.alert = '...' and self.notice = '...'. Add redirect_to url, :alert => '...' and :notice => '...'. Read more.
  • i18n: localize the label helper.

Active Record

  • Namespacing: support optional table name prefixes on modules by defining self.table_name_prefix. Read more.
  • Destroy uses optimistic locking.
  • Counter cache: use Post.reset_counters(1234, :comments) to count the number of comments for post 1234 and reset its comments_count cache.
  • PostgreSQL: always use standard-conforming strings, if supported.
  • MySQL: add index length support. Read more.
  • MySQL: add_ and change_column support column positioning using :first => true and :after => :other_column.

Active Support

  • Upgrade i18n from 1.3.3 to 1.3.7.
  • Upgrade TZInfo from 0.3.12 to 0.3.16.
  • Multibyte: speed up string verification and cleaning.
  • JSON: use YAJL for JSON decoding, if available. gem install yajl-ruby
  • Testing: add assert_blank and assert_present. Read more.
  • Core: backport Object#singleton_class from Ruby 1.8.8, deprecating our Object#metaclass.
  • Core: add Object#presence that returns the object if it’s #present? otherwise returns nil. Example: region = params[:state].presence || params[:country].presence || 'US'
  • Core: add Enumerable#exclude? to match include?.
  • Core: rename Array#rand to Array#random_element to avoid collision with Kernel#rand.
  • Core: rename Date# and Time#last_(month|year) to #prev_(month|year) for Ruby 1.9 forward compatibility.

Active Resource

  • JSON: set ActiveResource::Base.include_root_in_json = true to serialize as a hash of model name -> attributes instead of a bare attributes hash. Defaults to false.

Action Mailer

  • Upgrade TMail from 1.2.3 to 1.2.7.

Railties

  • Silence RubyGems 1.3.6 deprecation warnings.
