Thank you Niphlod, as always :)
I've seen your answer in the other post. Sorry for my lack of knowledge :P
Now I understand better.
I was dealing today with a strange error: the same code worked ok when I
run the app with web2py's embedded server, but the app couldnt connect to
redis when I used nginx (the logs showed that there was no redis instance
available, same message every two seconds, until it gave up). *But it was
fixed after restarting the OS*. Sorry, I've should tried that.
Anyway, this code is working ok:
from gluon.contrib.redis_cache import RedisCache
from gluon.contrib.redis_utils import RConn
rconn = RConn('localhost', 6379)
cache.redis = RedisCache(redis_conn=rconn, with_lock=True)
Thanks for your time, sorry for the bother!
Regards,
Lisandro.
