为什么棋牌室开着开着就倒闭了？
Django 今天发布了两个 bug 修复版本 Django 1.8.1 和 Django 1.7.8。
Django 1.8.1 修复了 1.8 的一些 bugs，同时优化了迁移框架：
Bug 修复
- Added support for serializing timedelta objects in migrations (#24566).
- Restored proper parsing of the testserver command’s positional arguments (fixture names) (#24571).
- Prevented TypeError in translation functions check_for_language() andget_language_bidi()when translations are deactivated (#24569).
- Fixed squashmigrations command when usingSeparateDatabaseAndState(#24278).
- Stripped microseconds from datetime values when using an older version of the MySQLdb DB API driver as it does not support fractional seconds (#24584).
- Fixed a migration crash when alteringManyToManyFields (#24513).
- Fixed a crash with QuerySet.update() on foreign keys to one-to-one fields (#24578).
- Fixed a regression in the model detail view ofadmindocs when a model has a reverse foreign key relation (#24624).
- Prevented arbitrary file inclusions in admindocs(#24625).
- Fixed a crash with QuerySet.update() on foreign keys to instances withuuid primary keys (#24611).
- Fixed database introspection with SQLite 3.8.9 (released April 8, 2015) (#24637).
- Updated urlpatterns examples generated by startproject to remove usage of referencing views by dotted path inurl() which is deprecated in Django 1.8 (#24635).
- Fixed queries where an expression was referenced in order_by(), but wasn’t part of the select clause. An example query isqs.annotate(foo=F('field')).values('pk').order_by('foo'))(#24615).
- Fixed a database table name quoting regression (#24605).
- Prevented the loss of null/not null column properties during field alteration of MySQL databases (#24595).
- Fixed JavaScript path of contrib.admin’s related field widget when using alternate static file storages (#24655).
- Fixed a migration crash when adding new relations to models (#24573).
- Fixed a migration crash when applying migrations with model managers on Python 3 that were generated on Python 2 (#24701).
- Restored the ability to use iterators as queryset filter arguments (#24719).
- Fixed a migration crash when renaming the target model of a many-to-many relation (#24725).
- Removed flushing of the test database with --keepdb, which prevented apps with data migrations from using the option (#24729).
- Fixed makemessages crash in some locales (#23271).
- Fixed help text positioning of contrib.admin fields that use theModelAdmin.filter_horizontaland filter_vertical options (#24676).
- FixedAttributeError: function ‘GDALAllRegister’ not founderror when initializingcontrib.gis on Windows.
优化
- Changed ModelState to deepcopy fields instead of deconstructing and reconstructing (#24591). This speeds up the rendering of model states and reduces memory usage when running manage.py migrate.
Django 1.7.8 主要是 bug 修复：
- Database introspection with SQLite 3.8.9 (released April 8, 2015) (#24637).
- A database table name quoting regression in 1.7.2 (#24605).
- The loss of null/not null column properties during field alteration of MySQL databases (#24595).
