将参数传递给Django / Allauth中的覆盖视图

使用Django 1.4和Allauth，我试图拥有2个不同的注册页面。当我说不同时，我的意思是2个不同的URL和“ html布局”。

这是我到目前为止所做的。它可以工作，但是不会将is_alternate_template变量传递给HTML模板：

在urls.py中：

url(r'^accounts/', include('allauth.urls')),
url(r'^abc/alternate-signup/?$','project.views.alternate_signup'),

在views.py中：

def alternate_signup(request):
    from allauth.account import views as account_views
    is_alternate_template = True
    return account_views.signup(request, locals(), context_instance=RequestContext(request))

在templates / account / signup.html中

{% if is_alternate_template %}
display the alternate layout of the signup page
{% else %}
display the 'standard' layout of the signup page
{% endif %}

在Allauth模块中，这是帐户/视图中注册视图的外观（这是我从Allauth模块覆盖的视图，而不是我自己写的视图）：

class SignupView(RedirectAuthenticatedUserMixin, CloseableSignupMixin, FormView):
    template_name = "account/signup.html"
    form_class = SignupForm
    redirect_field_name = "next"
    success_url = None

    def get_success_url(self):
        # Explicitly passed ?next= URL takes precedence
        ret = (get_next_redirect_url(self.request,
                                     self.redirect_field_name)
               or self.success_url)
        return ret

    def form_valid(self, form):
        user = form.save(self.request)
        return complete_signup(self.request, user,
                               app_settings.EMAIL_VERIFICATION,
                               self.get_success_url())

    def get_context_data(self, **kwargs):
        form = kwargs['form']
        form.fields["email"].initial = self.request.session.get('account_verified_email', None)
        ret = super(SignupView, self).get_context_data(**kwargs)
        login_url = passthrough_next_redirect_url(self.request,
                                                  reverse("account_login"),
                                                  self.redirect_field_name)
        redirect_field_name = self.redirect_field_name
        redirect_field_value = self.request.REQUEST.get(redirect_field_name)
        ret.update({"login_url": login_url,
                    "redirect_field_name": redirect_field_name,
                    "redirect_field_value": redirect_field_value })
        return ret

signup = SignupView.as_view()
