Python Django登录脚本不断返回无效请求

嗨，我希望有人能帮忙

我是Django新手，一直在按照教程制作登录脚本。我创建了一个脚本，允许用户从HTML表单使用postgres中的users表登录。尽管用户凭据正确，登录脚本始终返回“无效用户”。我已经遵循了许多故障排除指南，现在我已经筋疲力尽了，这真是令人沮丧。请参阅下面我的代码中的不同部分。任何帮助都将不胜感激

    destination = get_redirect_if_exists(request)
    print("destination: " + str(destination))

    if request.POST:
        form = AccountAuthenticationForm(request.POST)
        if form.is_valid():
            email = request.POST['email']
            password = request.POST['password']
            user = authenticate(email=email, password=password)
