更新到 1.4 后 Django syncdb 异常

Question

所以我在 Django 中开发一个应用程序，需要 1.4 版本的功能，所以我决定更新。
但是当我想做 syncdb
时出现了一个奇怪的错误我正在使用新的 manage.py，正如您所见，它制作了一些表格但随后失败了:

./manage.py syncdb
Creating tables ...
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_user_permissions
Creating table auth_user_groups
Creating table auth_user
Creating table django_content_type
Creating table django_session
Creating table django_site
Traceback (most recent call last):

TypeError: db_type() got an unexpected keyword argument 'connection'

Answer 1

我有同样的问题，我的自定义字段的定义缺少连接参数。

from django.db import models

class BigIntegerField(models.IntegerField):
    def db_type(self, connection):
        return "bigint"
