All of the above. My rule of thumb is: don't use them unless I
have a
very, very good reason. I can't think of the last time I had that
good a reason.
So.. you are saying that this is preferred:
class State < AR:Base
def self.names
@names ||= State.all.map{|s| s.name}
end
end
to this:
class State < AR:Base
def self.names
@@names ||= State.all.map{|s| s.name}
end
end
Is that correct?
How is using a class instance variable safer from a threading point
of view? Do threads not share class instance variables the same way
class variables would be shared?
