这个让我大吃一惊，并且让我大致相同程度。
我在这里有一个注册页面：http://eatfeastly.com（我在8月15日午夜重启了服务器，暂时解决了问题，所以你可能需要等待才能看到问题）
您会注意到它已经预先填充了一些用户的电子邮件。请注意，这意味着此数据不仅仅在我的缓存中。毫无疑问，这对我们的用户来说是 BAD 。
我使用以下MVT：
class PotentialUser(CommonInfo):
is_cook = models.BooleanField()
email = models.EmailField(unique=True, db_index=True, validators=[validate_no_existing_user_email])
location = models.CharField(max_length=500, help_text="Please enter city, state.")
zipcode = models.CharField(max_length=10, blank=True)
class LOCATION:
DC = "Washington, DC"
NY = "New York City, NY"
SF = "San Francisco, CA"
OTHER = "Other"
def __unicode__(self):
return self.email
def send_signup_email(self):
# Can't use django notifications here, since it requires an actual user, and this is only a potential user
msg = MultipartTemplateEmailMessage('signup_complete',
from_email=settings.DEFAULT_FROM_EMAIL,
to=[self.email],
part_templates=(
('full.txt', 'text/plain'),
),
context={
'recipient': self,
'support_email': settings.SUPPORT_EMAIL,
# shortened from:
# http://eatfeastly.com/?utm_source=cont-e-pot&utm_medium=email-auto&utm_content=feedme&utm_campaign=e-share
'share_url': "http://goo.gl/X2VtA",
},
)
msg.send()
class PotentialUserModelForm(forms.ModelForm):
# Override to make this field required
is_cook = forms.TypedChoiceField(
required=True,
coerce=bool,
choices=(
('cook', True),
('feaster', False),
('both', True),
)
)
class Meta:
model = PotentialUser
def clean(self):
cleaned_data = super(PotentialUserModelForm, self).clean()
location = cleaned_data.get('location')
if location == "Other":
zipcode = cleaned_data.get('zipcode')
if zipcode is None or zipcode == '':
if not 'zipcode' in self._errors:
self._errors['zipcode'] = ErrorList()
self._errors['zipcode'].append("Zipcode is required")
del cleaned_data['zipcode']
return cleaned_data
class PotentialUserCreateView(CreateView):
form_class = PotentialUserModelForm
template_name = "intro/home.html"
form_focused = False
def get_success_url(self):
return reverse_lazy('potential_user_thanks', self.object.pk)
def get_context_data(self, **kwargs):
kwargs['LOCATION'] = PotentialUser.LOCATION
if self.form_focused or hasattr(kwargs['form'], 'errors') and kwargs['form'].errors:
kwargs['form_focused'] = True
else:
kwargs['form_focused'] = False
return super(PotentialUserCreateView, self).get_context_data(**kwargs)
def form_valid(self, form):
# Save the user to the database and set self.object
response = super(PotentialUserCreateView, self).form_valid(form)
self.object.send_signup_email()
return response

这是另一个奇怪的问题：一些用户的电子邮件在数据库中没有关联的PotentialUser模型，而是有一个Django用户模型。
现在这里是踢球者：它不会发生在我的开发机器上，也不会发生在我们的暂存环境中。这两种环境都有自己的覆盖设置，但这些设置似乎没有任何影响。我自己只是在测试这个。
似乎解决了什么问题，重新启动服务器。在某些事情发生之前，另一个用户登录另一台计算机或其他东西（！？），并且用户的电子邮件开始显示在注册页面上。
可能导致这种情况的原因是什么？这可能是用户会话渗入其他连接吗？如果是这样，那是如何工作/发生的？最重要的是，我该如何解决这个问题？
谢谢！
