Upgrade from Django15 to Django16

Here again I am trying to upgrade my application from Django1.5 to Django1.6 which I documented here.

The bump I found in my code was the url import in urls.py

Before we import urls like this :

from django.conf.urls.defaults import *

In Django1.5 there was warning that this will be deprecated. Now in Django1.6 , the app wont start.

Instead we must use this for the import :

from django.conf.urls import *

The package moved to other place. This was a bit wow for a big applications where the urls.py spread all over the application.

For backward compatibility I use this import :

try:

    from django.conf.urls.defaults import *

except:

    from django.conf.urls import *

Then the other bump was the cache_page decorator. In Django 1.3 the usage was :

from django.views.decorators.cache import cache_page

urlpatterns = ('',
    (r'^foo/(\d{1,2})/$', cache_page(my_view, 60 * 15)),
)

In Django 1.4 the usage was :

from django.views.decorators.cache import cache_page

urlpatterns = ('',
    (r'^foo/(\d{1,2})/$', cache_page(60 * 15)(my_view)),
)

when in Django1.5 there were deprecated warning for the cache decorator. It said :

The cache_page decorator must be called like: cache_page(timeout, [cache=cache name], [key_prefix= key prefix])

And in Django1.6 there error came out in using cache decorator. How I use the cache decorator was  :

url(r'^sitemap\.xml$', cache_page(sitemap,LONG_CACHE), {'sitemaps': sitemaps}),

So to fix it, we need to change the calling of cache_page decorator. We call using the cache_page(timeout, viewfunc) so here are the fixed url :

url(r'^sitemap\.xml$', cache_page(LONG_CACHE)(sitemap), {'sitemaps': sitemaps}),

With this all working in my application.One thing which i concert is that johnnycache not working in Django1.6 which needed for cache all database query.

The most version updated version i use now will be Django 1.6.2 as per today 9 March 2014.

Hope this give hint for you who need upgrading also.
