Question

It’s possible to cache list with different types of objects in django? When i’m trying to do this, django always return None to me.

Check this code:

foo = Foo.objects.all()[:10]
bar = Bar.objects.all()[:10]
foobar = list(foo) + list(bar)
cache.set('foobar', foobar)
cache.get('foobar') # None

If this is normal behaviour, is there some workarounds?

Django could cache such list, you need to check

• cache.set('foo', 'bar') then get to ensure the cache works
• the log of the cache backend to know whether set succeeds
• for memcached backend, whether foobar is too big to fit in the cache
