Django框架MySQL数据库到models模型的映射关系

from django.db import models
 
# 积分信息
class Credits(models.Model):
    user = models.ForeignKey(Visitors,on_delete=models.CASCADE,primary_key=True)
    credits_total = models.IntegerField('总积分',default=0)
    credits_buy = models.IntegerField('购买的积分',default=0)
    time_credits_buy = models.DateTimeField('购买的时间',auto_now_add=True)
    credits_before_day = models.IntegerField('前一天签到的积分',default=0)
    time_sign_before_day = models.DateTimeField('前一天签到的时间',default=None)
 
    class Meta():
        # credits,为数据库中的表名
        db_table = 'credits'
