sounds like it's trying to cache a thread? that doesn't make a lot of sense... maybe more debug needed? what happens if you run without the block?
from dalli.
Hi, if I don't use "Rails.cache.fetch" and use just "active_deal" everything works.
from dalli.
What if you just use fetch without the block? Would help to pinpoint the issue.
from dalli.
Sorry but I don't know what you mean.
This does not work at all:
Rails.cache.fetch('all_active_deals', :expires_in => 10.minutes) active_deal
from dalli.
drop the active_deal and just use
Rails.cache.fetch('all_active_deals').
It obviously won't return anything if there is nothing stored already, but this would show if it is a Dalli issue or an issue with what you are trying to cache.
from dalli.
Just like you say it returns nothing. The dalli cache is working, I do have some fragments that I cache and there is no problem with it.
The mysterious thing is, that the error message from above just started showing as I switched to dalli. memcached-northscale worked but it doesn't run under Rails3 that why I switched to dalli.
from dalli.
so in rails console do something like
deals = active_deal
Rails.cache.write('all_active_deals', deals)
if that works, run
Rails.cache.fetch('all_active_deals')
and see what fails.
from dalli.
As plukevdh points out, your code is trying to cache a Thread instance, which does not work. Whatever active_deal returns, it contains a reference to a Thread somewhere.
from dalli.
I really don't know if there is a thread instance, I have to check it though.
@plukevdh: The cache.write fails. So it really looks like a thread problem. Like I said I have to check it.
Thanks guys.

Ok, after a lot of testing I found that I cannot store my named-scope in the cache.
Like I said, the mysterious thing is that it worked before with memcached-northscale. But like mperham pointed out - dalli cache works a bit different.
I will use fragment caching then.
Thanks.
