I have following models.py code:

class try(models.Model)
    date = models.CharField(max_length=10, blank=True, null=True) # statement no. 1
    #also tried this instead of statement no.1 :
    #date = models.DateField(blank=True, null=True)
    #other statements

Corresponding ModelForm code is:

class MyForm(ModelForm):
    filing_date = DateField(input_formats=['%d-%m-%Y'], widget=DateInput(format=('%d-%m-%Y'), attrs={'class':'input-block-level datePickBootstrap', 'placeholder':'Filing date'}))
    class Meta:
        model = try

如果"日期"字段留空,则会收到错误"此字段为必填项".考虑到我使用了"blank = True",我无法找出错误的原因.我也试过搜索"DateField"是否有任何问题.我怎么解决这个问题？我是新手.我已经发布了相关代码.
