python Django 迁移数据库数据错误TypeError: 'str' object is not callable

跪求大佬解救一下。。。

1. mysql 创建数据库表正常：create database auto_ui DEFAULT CHARACTER set utf8;

2. 进行数据迁移,Terminal中输入命令：
   python manage.py makemigrations
   python manage.py migrate
   输入报错：

   D:\wuyou_work\auto_ui>python manage.py migrate
   

   Traceback (most recent call last):

   TypeError: 'str' object is not callable

Answer 1

检查报错的行
str is not callable 一般发生在你搞错了变量的类型，或者调用属性加上了括号。
比如
class A:
  def __init__(seif):
    self.s = "aaa"

a = A()
print(a.s()) #错误，应该是 print(a.s)
