Question

我有一个像这样的django模型 -

class Transaction(models.Model):
    date = models.DateField()
    type = models.IntegerField(choices=TRANSACTION_TYPE)
    distributor = models.ForeignKey(Distributor)
    second_party = models.CharField(max_length=100)
    route = models.ForeignKey(DistributionRoute)
    total_price = models.FloatField()

    def __str__(self):
        return self.date + " " + " " +self.total_price

我试图从这个模型中创建一个表单 -

class transactionForm(forms.ModelForm):

    class Meta:
         model = Transaction
         fields = ['date', 'type', 'distributor', 'second_party', 'route', 'total_price']

但我经常遇到以下错误 -

File "/home/itsd/sts/transaction/forms.py", line 5, in <module>
class transactionForm(forms.ModelForm):
File "/home/itsd/venv/lib/python3.5/site-packages/django/forms/models.py", line 247, in __new__
opts.field_classes)
File "/home/itsd/venv/lib/python3.5/site-packages/django/forms/models.py", line 133, in fields_for_model
opts = model._meta
AttributeError: 'tuple' object has no attribute '_meta'

我被困在这里好几个小时。这个问题的原因是什么？

Django形成了AttributeError：＆＃39; tuple＆＃39;对象没有属性＆＃39; _meta＆＃39;
