1.在models.py檔案中新增程式碼

class notice(models.Model):
    notice_title = models.CharField(max_length=255)
    notice_content = models.TextField()
    notice_user = models.CharField(max_length=20)
    notice_user_id = models.IntegerField(max_length=11)
    notice_time = models.DateTimeField(auto_now_add=True)

    
 
def __str__(self):
        return self.notice_title

2.執行python manage.py makemigrations RRMS

3.檢視遷移將執行的SQL：python manage.py sqlmigrate RRMS 0001

4.遷移資料，資料庫中建立這些模型表：python manage.py migrate
