我是django框架中的新手,我正在尝试为“register”创建一个api,我希望在执行后将数据插入到db中但无法执行此操作。
我正在尝试创建auth_user的对象并尝试session.add(auth_user_object)
但它没有给出任何错误,甚至没有向mysql db添加数据。
我可以从db获取(获取)数据。
创建所有表格。
然后我正在做inspect db
并获取db表类并根据sqlalchemy修改它。
但是我无法使用sqlalchemy将数据添加到db表。
请帮帮我。 这样做的最佳方法是什么。

您不需要在Django中使用SQL alchemy。 Django提供ORM来进行数据库查询。你也可以像这样定义模型。
class UAuthUser(models.Model):
__tablename__='auth_user'
password = models.CharField(max_length=20)
last_login = models.DateField()

错误地我没有向Id提供数据类型,这就是为什么错误即将发生。
