Question

我在Django项目中使用Django-registration-email。在文档（Django-Registration-Email）中，我被指示在 settings.py 中添加 REGISTRATION_EMAIL_REGISTER_SUCCESS_URL 。但是，这会导致类型错误：

'str' object is not callable

在settings.py中，我将重定向网址设置为：

REGISTRATION_EMAIL_REGISTER_SUCCESS_URL = '/accounts/register/complete/'

并且URL被复制为：

url(
    r'^accounts/register/$',
    RegistrationView.as_view(
        template_name='registration/registration_form.html',
        form_class=CustomEmailRegistrationForm,
        get_success_url=getattr(
            settings,'REGISTRATION_EMAIL_REGISTER_SUCCESS_URL',
            lambda request, user:'/'),
    ),
    name='registration_register',
),

调试信息告诉我第一个错误来自form_valid 中的 /local/lib/python2.7/site-packages/registration/views.py

指示的错误行是

success_url = self.get_success_url(request, new_user)

整个区块是

def form_valid(self, request, form): new_user = self.register(request, **form.cleaned_data) success_url = self.get_success_url(request, new_user) # success_url may be a simple string, or a tuple providing the # full argument set for redirect(). Attempting to unpack it # tells us which one it is. try: to, args, kwargs = success_url return redirect(to, *args, **kwargs) except ValueError: return redirect(success_url)

追溯是：

Traceback: File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response 114. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/views/generic/base.py" in view 69. return self.dispatch(request, *args, **kwargs) File "/Library/Python/2.7/site-packages/registration/views.py" in dispatch 79. return super(RegistrationView, self).dispatch(request, *args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/views/generic/base.py" in dispatch 87. return handler(request, *args, **kwargs) File "/Library/Python/2.7/site-packages/registration/views.py" in post 35. return self.form_valid(request, form) File "/Library/Python/2.7/site-packages/registration/views.py" in form_valid 83. success_url = self.get_success_url(request, new_user) Exception Type: TypeError at /accounts/register/ Exception Value: 'str' object is not callable

有人可以帮我解决这个问题吗？非常感谢！我被这个问题困住了一整天！

Answer 1

好的，当你使用

时

get_success_url=getattr(
        settings,'REGISTRATION_EMAIL_REGISTER_SUCCESS_URL',
        lambda request, user:'/'),
)

在您的网址处理程序中，您将get_success_url设置为字符串。然后，您在form_valid中将其作为函数调用，尝试传递变量。

最后，我发现问题出在哪里： REGISTRATION_EMAIL_REGISTER_SUCCESS_URL期待的是函数而不是字符串

所以，我应该在settings.py

中添加一行功能

REGISTRATION_EMAIL_REGISTER_SUCCESS_URL = lambda request, user: '/activate/complete/'

无论如何，我仍然愿意转向allauth，因为不再维护django-registration-email。
