验证错误在[u'以YYYY-MM-DD HH:MM [:ss [.uuuuuu]]格式输入有效日期/时间.']

Question

forms.py

class SearchFilterForm(Form):
    fromdate = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'dd/mm/yy','class':'datefield','readonly':'readonly'}))
todate = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'dd/mm/yy','class':'datefield','readonly':'readonly'}))

models.py

class Report(models.Model):
    user = models.ForeignKey(User, null=False)
    created_date_time = models.DateTimeField('Created')
    sent_date_time = models.DateTimeField('Sent')

在数据库中,日期对象以这种格式保存,YYYY-MM-DD HH:MM我在forms.py中使用,格式是dd/mm/yyyy.如果我在表单中使用yyyy-mm-dd格式,我没有收到任何错误.因为我使用了dd/mm/yyyy格式表单我收到此验证错误.我想知道如何处理这个问题.

您应该DateField在表单中使用a 并配置input_formats为支持您要使用的格式:

ACCEPTABLE_FORMATS = ['%d-%m-%Y',       # '25-10-2006'
                      '%d/%m/%Y',       # '25/10/2006'
                      '%d/%m/%y']       # '25/10/06'
                      # Add your own at will, but be mindful of collisions.


class SearchFilterForm(Form):    
    fromdate = forms.DateField(input_formats=ACCEPTABLE_FORMATS)
    todate = forms.DateField(input_formats=ACCEPTABLE_FORMATS)

更好的是,您可以在Django应用程序中启用本地化,让django自动为您使用正确的格式!

# settings.py
USE_L10N = True

# forms.py
class SearchFilterForm(Form):    
    fromdate = forms.DateField(localize=True)
    todate = forms.DateField(localize=True)
