Django 1.11.4 发布，Python 的 Web 框架

Linuxeden 开源社区 --

Django 是一个高级的 Python Web 框架，旨在快速开发和简单，实用的设计。

Django 1.11.4 已发布，该版本修复了 1.11.3 中的一些 bug ，具体如下：

• Fixed a regression in 1.11.3 on Python 2 where non-ASCII “format“ values for date/time widgets results in an empty “value“ in the widget’s HTML
• Fixed “QuerySet.union()“ and “difference()“ when combining with a queryset raising “EmptyResultSet“
• Fixed a regression in pickling of “LazyObject“ on Python 2 when the wrapped object doesn’t have “__reduce__()“.
• Fixed crash in “runserver“’s “autoreload“ with Python 2 on Windows with non-“str“ environment variables.
• Corrected “Field.has_changed()“ to return “False“ for disabled form fields: “BooleanField“, “MultipleChoiceField“, “MultiValueField“, “FileField“, “ModelChoiceField“, and “ModelMultipleChoiceField“.
• Fixed “QuerySet.count()“ for “union()“, “difference()“, and “intersection()“ queries.
• Fixed “ClearableFileInput“ rendering as a subwidget of “MultiWidget“ . Custom “clearable_file_input.html“ widget templates will need to adapt for the fact that context values “checkbox_name“, “checkbox_id“, “is_initial“, “input_text“,“initial_text“, and “clear_checkbox_label“ are now attributes of “widget“ rather than appearing in the top-level context.
• Fixed queryset crash when using a “GenericRelation“ to a proxy model
