Question

我收到的格式错误表示字段不是日期格式字段。我不知道为什么它会给我一个与我想填写的表格字段无关的表格...

以下是显示的确切错误：

以下是模型文件：

class Profile(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)  # server
    first_name = models.CharField(max_length=25, default='first')
    last_name = models.CharField(max_length=25, default='last')
    dob = models.DateField(default='0')
    city = models.CharField(max_length=45, default='city')  # user
    state = models.CharField(max_length=25, default='state')
    phone = models.BigIntegerField(default=0)  # user
    privacy = models.SmallIntegerField(default=1)  # user
    balance = models.DecimalField(decimal_places=2, max_digits=9, default=0)
    created = models.DateTimeField(auto_now_add=True)  # server

这是form.py：

class TransferForm(forms.ModelForm):
    acct_choices = (('Tabz', 'Tabz - Username'),
                    ('Wells Fargo', 'Wells Fargo - Username'))
    main = forms.TypedChoiceField(
        choices=acct_choices
    )
    transfer = forms.TypedChoiceField(
        choices=acct_choices
    )
    class Meta:
        model = Transfers
        fields = ['main', 'transfer', 'amount', 'memo']

这是处理表单并创建新配置文件的部分：

错误在第9-14行

if main == 'Tabz':
                    profiles = Profile.objects.all()
                    for profile in profiles:
                        if currentUser == profile.user:
                            currentProfile = profile
                            currentProfile.balance = currentProfile.balance - amount
                            currentProfile.save()

                                balance = new_balance,
                            )

                if transfer == 'Tabz':

                            currentProfile = profile
                            currentProfile.balance = currentProfile.balance + amount
                            currentProfile.save()
                        else:
                            new_balance =  amount
                            new_profile =  Profile.objects.create(
                                user = currentUser,
                                balance = new_balance
                            )
                    message = 'You have transfered ' + amount + ' from your Tabz account to main account'
                    new_activity = Acitivty.objects.create(

                return redirect('home_page')

Answer 1

因为您已经使用了DateField，并且您提供了一个defualt值为0，因此错误即将来临，

所以改变这一行

dob = models.DateField(default='0')

到

dob = models.DateField(default='1900-01-01')

然后makemigrations和migrate。然后尝试提交表单
