1、class Entry(models.Model):
"""学到的有关某个主题的具体知识"""
topic = models.ForeignKey(Topic,on_delete=models.CASCADE)
text = models.TextField()
date_added = models.DateTimeField(auto_now_add = True)
报错TypeError: __init__() missing 1 required positional argument: 'on_delete'
这里需要添加一个参数
2、在topic = models.ForeignKey(Topic)之后添加“on_delete=models.CASCADE”如图所示
3、以上就是对于TypeError: __init__() missing 1 required positional argument: 'on_delete'错误的更改方法
4、如果有帮助到您，就帮我投个票吧，谢谢
