How does the proc in the caches_action if clause get execute
- by Sid
I have a newbie kind of question which I cant get my head around. How does the Proc in the if condition of the caches_action get executed for the caches_action method.
for example
caches_action :show, :if=Proc.new{|x| something}
what i dont get its how does this get called.
I know i can execute a proc defined as
proc= Proc.new by
proc.call
so i dont understand how this gets called.
Second how do I pass conditions like
if logged_in?
I'd appreciate any help on this
