DJANGO:ValidationError[“'journals\u Start\u Date'值的日期格式无效。必须是YYYY-MM-DD格式。“]

我要执行以下操作:

 journal.objects.filter(Q(User=request.user) | Q(Date__range=[('journals__Start_Date'),('journals__End_Date')])

class journal(models.Model):
    User = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,null=True,blank=True)
    Company = models.ForeignKey(company,on_delete=models.CASCADE,null=True,blank=True,related_name='Companyname')
    Date = models.DateField()
    By = models.ForeignKey(ledger1,on_delete=models.CASCADE,related_name='Debitledgers')
    To = models.ForeignKey(ledger1,on_delete=models.CASCADE,related_name='Creditledgers')
    Debit = models.DecimalField(max_digits=10,decimal_places=2)
    Credit = models.DecimalField(max_digits=10,decimal_places=2)

class selectdatefield(models.Model):
    Journal = models.ForeignKey(journal,on_delete=models.CASCADE,null=True,blank=True,related_name='journals')
    Start_Date = models.DateField(blank=True, null=True)
    End_Date = models.DateField(blank=True, null=True)

有人知道我的代码有什么问题吗?

我用了F表达式,但它不过滤日期范围。。。
