Question

使用Stripe API在我的网站上创建信用卡结帐表格。我正在尝试在应用结帐的view.py中测试以下行。

print (request.user.userStripe.stripe_id)

这可能是设置用户的方式。我尝试从用户应用程序导入模型。我只是不明白为什么看不到它。

我有两个应用：用户和结帐

我在调试页面中遇到以下错误

Answer 1

您应使用小写的型号名称print(request.user.userstripe.stripe_id)。最好在related_name中设置OneToOneField，以便您确切地知道如何从userStripe访问user。

class userStripe(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='user_stripe')
    ...

print(request.user.user_stripe.stripe_id)

Answer 2

使用“ request.user.userStripe.stripe_id”您正在使用request.User，而您必须使用

“” request.user“”

Answer 3

您错过了在打印中键入userStripe（request.user.userStripe.stripe_id）尝试写userstripe： 打印（request.user.userstripe.stripe_id） 对我来说非常好

AttributeError'用户'对象没有属性'userStripe'
