Basic urls


from django.conf.urls import url
from boards import views

urlpatterns = [
    url(r'^$', views.home, name='home'),
    url(r'^about/$', views.about, name='about'),
]

Deeper URL structures:


urlpatterns = [
    url(r'^$', views.home, name='home'),
    url(r'^about/$', views.about, name='about'),
    url(r'^about/company/$', views.about_company, name='about_company'),
]

Advanced urls (with regex) eg: this will create a url of each username

from django.conf.urls import url
from boards import views

urlpatterns = [
    url(r'^$', views.home, name='home'),
    url(r'^(?P[\w.@+-]+)/$', views.user_profile, name='user_profile'),
]
