Following is
account/url.pygiven 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"^$",SignupView.as_view(template_name="homepage.html"), name="account_signup"),
url(r"^$", LoginView.as_view(template_name="homepage.html"), name="account_login"),
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.
解决方法:
不要这样做.试着了解浏览器和网络服务器之间的情况. URL标识服务器将返回给客户端的内容.拨打2个“意见”违反了该原则.
您真正想要做的是创建一个新URL,或修改模板以将两个表单放在同一页面上.我可能会重命名SignupOrLoginView并在该单一视图中进行注册工作.
这在功能视图中更容易理解,而不是基于类的视图,这似乎将您限制为单个表单.
