Django Python WEB开发框架
Django是一个开放源代码的Web应用框架，由Python写成。采用了MVC的软件设计模式，即模型M，视图V和控制器C。它最初是被开发来用于管理劳伦斯出版集团旗下的一些以新闻内容为主的网站的，即是CMS（内容管理系统）软件。并于2005年7月在BSD许可证下发布。这套框架是以比利时的吉普赛爵士吉他手Django Reinhardt来命名的。
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 1.11.3 已发布，该版本修复了 1.11.2 中的一些 bug ，具体如下：
Removed an incorrect deprecation warning about a missing renderer argument if a Widget.render() method accepts **kwargs
Fixed a regression causing Model.__init__() to crash if a field has an instance only descriptor
Fixed an incorrect DisallowedModelAdminLookup exception when using a nested reverse relation in list_filter
Fixed admin’s FieldListFilter.get_queryset() crash on invalid input
Fixed invalid HTML for a required AdminFileWidget
Fixed model initialization to set the name of class-based model indexes for models that only inherit models.Model
Fixed crash in admin’s inlines when a model has an inherited non-editable primary key
Fixed QuerySet.union(), intersection(), and difference() when combining with an EmptyQuerySet
Prevented Paginator’s unordered object list warning from evaluating a QuerySet.
Fixed the value of redirect_field_name in LoginView’s template context. It’s now an empty string (as it is for the original function-based login() view) if the corresponding parameter isn’t sent in a request (in particular, when the login page is accessed directly).
Prevented attribute values in the django/forms/widgets/attrs.html template from being localized so that numeric attributes (e.g. max and min) of NumberInput work correctly
Removed casting of the option value to a string in the template context of the CheckboxSelectMultiple, NullBooleanSelect, RadioSelect, SelectMultiple, and Select widgets . In Django 1.11.1, casting was added in Python to avoid localization of numeric values in Django templates, but this made some use cases more difficult. Casting is now done in the template using the |stringformat:'s' filter.
Prevented a primary key alteration from adding a foreign key constraint ifdb_constraint=False
Fixed UnboundLocalError crash in RenameField with nonexistent field
Fixed a regression preventing a model field’s limit_choices_to from being evaluated when a ModelForm is instantiated
