我已成功完成了对这些命令的所有迁移。
python manage.py makemigrations senty
python manage.py migrate
我最终得到了这个错误：

对我来说，看起来“点”就在课堂上，并且它已成功迁移。最新的pycache也有正确的类版本，之前是错误的。直到我从一个不同的函数调用中更改了点，我才得到错误。
相当缺乏mysql，所以这是一个艰难的。我是否必须以某种方式手动添加列？
models.py
from django.db import models
from datetime import datetime
from decimal import Decimal
class score(models.Model):
ticker = models.CharField(max_length=10)
points = models.DecimalField(max_digits=4, decimal_places=1)
created_at = models.DateTimeField(default=datetime.now, blank=True)
MakeMigrations输出：
