Django 2.1 TypeError:__init __()获得了意外的关键字参数'on_delete' [英] Django 2.1 TypeError: __init__() got an unexpected keyword argument 'on_delete'

问题描述

我的代码:

class UserProfile(models.Model):
    user      = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='profile')
    following = models.ManyToManyField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='followed_by')

    def __str__(self):
        return str(self.following.all().count())

我的错误:

TypeError: __init__() got an unexpected keyword argument 'on_delete'

有什么想法吗?

推荐答案

查看

Looking at the docs, it seems that the field ManyToManyField does not have an argument called on_delete.

删除以下字段的参数以下:

...
user = models.OneToOneField(
    settings.AUTH_USER_MODEL,
    on_delete=models.CASCADE,
    related_name='profile')
following = models.ManyToManyField(
    settings.AUTH_USER_MODEL,
    related_name='followed_by')
...
