从adaptor.model导入CsvModel

Question

我正在尝试使用来自django适配器的CsvModel模块。但是，当我使用from adaptor.model导入CsvModel和makemigrations时，会出现以下错误。

有人能告诉我原因吗？我在模型中的代码如下：

from django.db import models
from adaptor.model import CsvModel
from adaptor.fields import CharField, DecimalField


class User(models.Model):
    user_name = models.CharField(max_length = 50, null=True, unique=True)

    def __str__(self):
        return self.user_name


 class Profile(models.Model):
    rubbish = models.DecimalField(max_digits= 1000, decimal_places=3, null=True)
    user = models.CharField(max_length = 50, unique = True, null=True)
    hobby = models.CharField(max_length = 50, null=True)
    job = models.CharField(max_length = 60, null=True)

class Trial(CsvModel):
    rubbish = DecimalField()
    user = CharField()
    hobby = CharField()

    class Meta:
        dbmodel = Profile
        delimiter = ','
        has_header = True

错误消息如下：

您正在使用python3.6，但是这个库看起来是为python2.5创建的--对于Python 3，它应该是

except ValueError as e:

您可能需要找到一个与django-csvimport不同的csv插件，并可能相应地更改策略。
