django-tables2 LinkColumn正确显示日期

Question

我目前正在使用Django 1.11.2和django-tables2进行一个项目。我用一张桌子来显示我的模型。该模型有一个DateTimeField，它在普通列中正确显示，但是当我使用带有此DateTimeField的LinkColumn时，日期以复杂的格式显示，如下所示：'2017-02-23 07：49：53.067504 + 00:00 '而不是'23 .02.2017 07:49'。 链接工作正常，但我找不到回归简单格式的方法。

我的模型在models.py中：

class mymodel(models.Model):
Date = models.DateTimeField(auto_now_add=True, help_text='(Format: TT.MM.JJJJ)')

...other fields...

class Meta:
    ordering = ["Date"]
    verbose_name = "MyModel"
    verbose_name_plural = "MyModels"

和表格：

class MyModelTable(django_tables2.Table):
Date = django_tables2.LinkColumn(viewname='MyModelView', kwargs={"id": Accessor("id")})
class Meta:
    model = MyModel
    exclude = {'id'}
    attrs = {"class": "paleblue"}

提前感谢任何帮助或想法。

LinkColumn converts the value in the column to string and doesn't care about dates. You can use the text argument to LinkColumn to pass a callable to use render the value in a custom way.

For example:

class MyModelTable(django_tables2.Table):
    Date = django_tables2.LinkColumn(
        viewname='MyModelView', 
        kwargs={"id": Accessor("id")},
        text=lambda record: record.Date.strftime('%x %X')
    )

    class Meta:
        model = MyModel
        exclude = {'id'}

Will render both date and time using format string %x %X, documentation here.

Note that if this field is nullable, you should add a check for that in the callable you pass with text.
