Question

Following is view.py which includes signup/loginview

Following is account/url.py given by Pinax

account/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")),
)

我正在尝试做的事情:调用 homepage.html 上的两个 View 。它在单个 html 中包含两种形式。

Answer 1

不要这样做。试着全神贯注于浏览器和网络服务器之间发生的事情。 URL 标识服务器将返回给客户端的内容。调用 2 个“ View ”违反了该原则。

您真正想要做的是创建一个新的 URL，或者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 View 中完成注册工作。

这在功能 View 中会更容易理解，而不是基于类的 View ，后者似乎将您限制在单一形式。
