Rails - Jun 2005 - Fragment Caching, again

We have our controller FooController, with action bar().  

def bar
    @list = MyModel.find( :all )
    @tmp = MyOtherModel.find( :all )
end

In my view, I am doing a fragment cache of the segment which uses
@tmp, but not @list.

My question then, is does MyOtherModel.find( :all ) still get
executed, because the action bar() must still be execute to generate
@list?  If so, what would be the benefit of a fragment cache of the
@tmp rendering?

And, while I might have someones attention here: I''m getting a
NoMethodError exception when I try and call expire_fragment(
:controller => ''ctrl'' , :action =>
''foo'', :action_suffix => ''asdf'' )
from inside my Observer... I thought that was *exactly* where I was
supposed to making these calls ...

>> My question then, is does MyOtherModel.find( :all ) still get

Yes ... The fragment cache is a part of the view - the action knows
nothing about it directly
>> If so, what would be the benefit of a fragment cache of the @tmp
rendering?

The main benefit of the fragment cache [as I understand it] is to reuse
the rendering cpu cycles where only a part of the action/view is
cacheable due to changing data or security considerations.

In fact, I have ''pushed'' a find or two from my actions into
the view so
that they are also ''cached''. I know it sounds bad, but
performance wise
it was worth it.
