-------------------------+-------------------------------------------------
In Django 1.9 and prior, we can use a date widget in Admin for a
`datetime` field. Specifically, we can override the default `datetime`
widget in Admin using `AdminDateWidget`. In this way, user are only
require to enter a ''date''. The ''time'' will be default 0h 0m 0s.
From Django 1.10 onwards, this behaviour has break. Now, there is an error
`Enter a list of values.` on save in Admin.
Example code.
Model:
{{{
class Highlight(models.Model):
end_at = models.DateTimeField()
def save(self, *args, **kwargs):
# Add 23 hours, 59 minutes, 59 seconds to end_at so that it
represent end of day.
extratime = timedelta(hours=23, minutes=59, seconds=59)
if self.end_at:
self.end_at = self.end_at + extratime
super(Highlight, self).save(*args, **kwargs)
}}}
Admin:
{{{
class HighlightAdmin(admin.ModelAdmin):
formfield_overrides = {
models.DateTimeField: {'widget': widgets.AdminDateWidget},
}
}}}
Now there is no easy way to let user only input the ''date'' part of
`datetime`field in Admin.
