Django报错:missing 1 required positional argument: 'on_delete' 问题解决方案

问题详情:
TypeError: init() missing 1 required positional argument: ‘on_delete’

出错地点:

File "E:\08-project\blogproject\blogproject\comments\models.py", line 13, in Comment
    post = models.ForeignKey('blog.Post')
TypeError: __init__() missing 1 required positional argument: 'on_delete'

出错原因:
在django2.0后,定义外键和一对一关系的时候需要加on_delete选项,这在1.0+的django版本中是默认参数
