Django 管理站点。 'Delete multiple objects' 产生 ValidationError
Django administration Site. 'Delete multiple objects' produces ValidationError
尝试删除与其他两个表具有一对一关系的多行时，我收到以下错误：
['“March 21, 2022” value has an invalid date format. It must be in YYYY-MM-DD format.']
模型设置如下：
class Media(models.Model):
date = models.DateField(primary_key=True, unique=True)
received_url = models.CharField(max_length=200, blank=True, null=True)
class Api(models.Model):
media = models.OneToOneField(Media, on_delete=models.CASCADE)
request_url = models.CharField(max_length=200)
class Text(models.Model):
media = models.OneToOneField(Media, on_delete=models.CASCADE)
title = models.CharField(max_length=100)
copyright = models.CharField(max_length=200, blank=True, null=True)
我正在尝试删除 主页 › My_App_Main › 媒体 › 从 Django 管理站点[=68] 删除多个对象 =].这向我展示了以下内容：
你确定吗？
您确定要删除选定的媒体吗？以下所有对象及其相关项目都将被删除：

先触发再触发错误。
检查浏览器网络日志中的 POST 请求，我注意到日期格式似乎有误：
_selected_action […]
0 "March+21,+2022"
1 "March+20,+2022"
action "delete_selected"
post "yes"
我在 Firefox 和 Chrome 中都试过了。
检查来自 Django 的数据 shell 没有发现不正确的地方。数据按预期返回：
>>> for field in Media.objects.all():
... print(f'{type(field.date)}({field.date})')
...
<class 'datetime.date'>(2022-03-21)
<class 'datetime.date'>(2022-03-20)
>>> for field in Text.objects.all():
... print(f'{type(field.media.date)}({field.media.date})')
...
<class 'datetime.date'>(2022-03-21)
<class 'datetime.date'>(2022-03-20)
>>> for field in Api.objects.all():
... print(f'{type(field.media.date)}({field.media.date})')
...
<class 'datetime.date'>(2022-03-21)
<class 'datetime.date'>(2022-03-20)
在我看来，这可能与 Django 管理站点对日期格式做了一些奇怪的事情有关？或者可能是浏览器默认设置问题？或者甚至是我需要在 Django 设置文件中设置的内容？如果是这种情况，人们将如何改变这种行为？
