django 定出从时日现场到现场的日期
原标题:django set DateField from a DateTimeField

我的问题是:

class A(models.Model):
  x = DateTimeField(...)

class B(models.Model):
  x = DateField(...)

鉴于A和B的事例,我如何简单地将b.x设定为a.x? 简单地将b.x设定为a.x,结果就没有。

提前感谢。

最佳回答

使用<代码> 日期.datetime.date() 查询date 构成部分如下:

a = A()
b = B()

# Stuff

b.x = a.x.date()
