Python Django:当用户存在于数据库中时，登录页未进行身份验证

我对这件事很陌生，如果这是显而易见的，我很抱歉。“我的视图”中的“注册”方法非常有效，它使用所有正确的凭据将用户添加到数据库中。但是，

登录

时不会。它似乎一直在告诉我，我的登录详细信息无效（在

视图.log_in

中打印的语句），当我尝试以这种方式与超级用户登录时，我得到：

WSGIRequest的反向：找不到POST“/login/”

        if form.is_valid():
            form.save()
            return index(request)
        else:
            print("form invalid")
    return render(request, 'html/sign_up.html', {'form': form})

我环顾了所有类似的问题，但仍然找不到我的代码的问题

非常感谢

回溯显示，此错误不是来自失败的登录，而是来自您在成功登录时所做的操作。调用重定向函数，但向其传递请求和模板名称，这是投标函数的参数

您应该通过传递路径或URL名称来解决此问题：

return redirect("index")

---

您似乎有一个自定义的用户模型。因此，您应该设置该设置。否则，默认身份验证后端将不使用您的自定义模型。之后，您应该删除数据库并重新进行迁移。。。。但这些都与您的问题无关，正如错误所说，这与URL有关。但是，您没有显示完整的错误消息，因此无法判断问题发生在何处。@DanielRoseman主要的一点是，它没有在数据库中找到用户，即使他们在那里-它给了我一个无效的登录，而不是一个错误。我所指的错误来自于在同一个登录表单中尝试管理员凭据-如果有帮助的话，我现在就把这个错误写出来了。谢谢。谢谢你的评论，你解决了2个问题中的1个，所以首先谢谢你：）当登录超级用户而不是普通用户时，它似乎可以工作，你知道为什么吗？我已经正确注册了一个用户，但无法将其记录在您如何定义超级用户？您的模型中没有该字段。事实上，我根本看不出这是如何工作的，因为您也没有is_活动字段、散列密码、从AbstractBaseUser继承，或者将AUTH_USER_模型设置为指向您的用户模型。
