Docs for cache_page:
https://docs.djangoproject.com/en/dev/topics/cache/?from=olddocs#django.views.decorators.cache.cache_page
They point out a `cache` keyword argument one can use:
cache_page can also take an optional keyword argument, cache, which
directs the decorator to use a specific cache alias when caching view
results. By default, the default alias will be used, but you can specify
any cache alias you want
I assume this means I can specify the cache_key to use. So, like the docs
state I try this out:
@cache_page(60 * 15, cache="special_cache")
def my_view(request):
....
As soon as I do this I get a ValueError with the following exception &
traceback:
"need more than 1 value to unpack"
