python – 如何在pinax中的一个url上调用多个视图

Following is view.py which includes signup/loginview

Following is account/url.py given by Pinax

帐户/ url.py

from accounts.views import SignupView,LoginView,LogoutView,DeleteView
from accounts.views import ConfirmEmailView
from accounts.views import ChangePasswordView,PasswordResetView,PasswordResetTokenView
from accounts.views import SettingsView,Signup_login


urlpatterns = patterns("",url(r"^signup/$",SignupView.as_view(),name="account_signup"),url(r"^login/$",LoginView.as_view(),name="account_login"),url(r"^logout/$",LogoutView.as_view(),name="account_logout"),url(r"^confirm_email/(?P<key>w+)/$",ConfirmEmailView.as_view(),name="account_confirm_email"),url(r"^password/$",ChangePasswordView.as_view(),name="account_password"),url(r"^password/reset/$",PasswordResetView.as_view(),name="account_password_reset"),url(r"^password/reset/(?P<uidb36>[0-9A-Za-z]+)-(?P<token>.+)/$",PasswordResetTokenView.as_view(),name="account_password_reset_token"),url(r"^settings/$",SettingsView.as_view(),name="account_settings"),url(r"^delete/$",DeleteView.as_view(),name="account_delete"),url(r"^signup.login/$",Signup_login.as_view(),name="Signup_login"),)

And following is my project’s app/url.py

url.py

urlpatterns = patterns("",url(r"^$",SignupView.as_view(template_name="homepage.html"),LoginView.as_view(template_name="homepage.html"),url(r"^admin/",include(admin.site.urls)),url(r"^account/",include("accounts.urls")),)

我要做的是：在homepage.html上调用两个视图.它在单个html中包含两种形式.
