Python Django日期字段，不带年份

python django

Python Django日期字段，不带年份,python,django,datefield,Python,Django,Datefield,是否可以有一个没有年份的日期字段？还是我要用查菲尔德？我正在使用管理员编辑模型。ADateField是一个完整的日期。如果您只关心月份和日期，那么在查询时使用\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu 如果您只想让表单显示日期和月份，则需要编写一个自定义小部件并将其连接到ModelAdmin类中

DateField
是一个完整的日期。如果您只关心月份和日期，那么在查询时使用
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

如果您只想让表单显示日期和月份，则需要编写一个自定义小部件并将其连接到ModelAdmin类中的表单。Django的文档很好地介绍了写作和写作

在这两种情况下，对现有模型/小部件进行子类化并更改所需的行为要容易得多。
这对我很有用：


data_sorted = sorted(My_Model.objects.all(), key=lambda e: e.myDataField.strftime("%m-%d"))



因此，如果我想检索今天之后所有日期的查询集，它应该是这样的：
today=datetime.date.today（）对象.Object.filter（date\uu day=today）.exclude（）谢谢
