Hi,all: My study at horizon src has been going on for some time.Now I could create a penal on it and present something. Anyway,a question has been boring me at the same time. What exactly the url rule is and how it works . src eg:urlpatterns = patterns('horizon.dashboards.syspanel.test.views', url(r'^$', IndexView.as_view(), name='index'),) Only a "r'^$'" could know where the page direct? Who knows the detail about it,please tell me. I greatly appreciate it! -------------- next part -------------- An HTML attachment was scrubbed...
