Django learning knowledge point summary (url)

Question 1:

Different django versions have different url styles

There are differences in the configuration of urls.py in django1.8 and urls.py in django1.6

In django1.6:

urlpatterns = patterns(‘’,

               url(r'^blog/index/$','blog.views.index'),

               url(r'^blog/time/$','blog.views.time'),

)

or

urlpatterns = patterns(‘blog.views’,

               url(r'^blog/index/$','index'),

               url(r'^blog/time/$','time'),

)

In django1.8:

from blog import views # django1.8 and later versions require that the former improt be used normally

urlpatterns = [

    url(r'^blog/index/$',views.index),#Note here, single/double quotation marks are cancelled

    url(r'^blog/time/$', views.time),

]

or

urlpatterns = [

    url(r'^blog/index/$','blog.views.index'),#Note that single/double quotes can still be used here

    url(r'^blog/time/$', ’blog.views.time‘),

]

The first one is recommended in django1.8. There are intelligent reminders and error reporting mechanisms in pycharm, so there will be no errors.
