Javascript Django：日期格式管理和唯一性结合起来->&引用；2020年3月20日“；值的日期格式无效。它必须是YYYY-MM-DD格式。”；]

我用国际化英语/法语开发了一个Django项目

当用户webbrowser为FR时，日期必须以dd/mm/yyyy格式显示；当用户webbrowser为EN时，日期必须以yyyy-mm-dd格式显示

为此，我使用JS测试webbrowser用户最喜欢的语言和相应的显示格式

这很好，直到我将模型更改为将unique_与此日期一起添加约束

现在，当webbrowser使用法语时，我遇到了一个错误，我尝试注册日期（asp\u entu dat）

型号。py:

    med_num = models.CharField("Trial batch number", max_length=3, null=True, blank=True,)
    asp_ent_dat = models.DateField("Entry date", null=True, blank=True)
    asp_ent_pro_pay = models.CharField("Country of treatment origin in case of entry", max_length=10, null=True, blank=True)
    asp_ent_pro_sit = models.CharField("Processing source site in case of entry", max_length=10, null=True, blank=True)

感谢您的回复，我添加了日期输入格式['%Y-%m-%d'，'%d/%m/%Y'，]，但仍然存在错误2020年3月20日（'%d/%m/%Y'）似乎不是文档中授权的格式列表，我将测试它。这对我有用。您使用的是什么
