我正在尝试使用django基于类的视图创建密码重置功能。我已经在django中实现了所有推荐的功能，但是有些不适合。每当我尝试单击“发送密码重置电子邮件”链接按钮时。它将字符串索引超出范围错误。
这是我的urls.py
urlpatterns = [
path('admin/', admin.site.urls),
path('register/',User_views.register, name='register'),
path('profile/',User_views.profile, name='profile'),
path('login/' , auth_views.LoginView.as_view(template_name='Users/login.html'), name='login'),
path('logout/', auth_views.LogoutView.as_view(), name='logout'),
path('password-reset/',
auth_views.PasswordResetView.as_view(
template_name='users/password_reset.html'
),
name='password_reset'),
path('password-reset/done/',
auth_views.PasswordResetDoneView.as_view(
template_name='users/password_reset_done.html'
),
name='password_reset_done'),
path('password-reset-confirm/<uidb64>/<token>/',
auth_views.PasswordResetConfirmView.as_view(
template_name='users/password_reset_confirm.html'
),
name='password_reset_confirm'),
path('password-reset-complete/',
auth_views.PasswordResetCompleteView.as_view(
template_name='users/password_reset_complete.html'
),
name='password_reset_complete'),
path('', include ('blog.urls')),
]
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
