But Memcached round trips are pretty cheap, since everything is in memory. > There isn't really a great way to say in rails "this code here only > exists to support this fragment in the view, so don't bother executing > it if you're just going to display the fragment from the cache > anyway". > In some cases wrapping the database access up in a helper can work, > but calling models straight from your helpers isn't particularly nice. I think DB access in a helper breaks MVC in most cases, because the helper is really part of the view layer. Concerns like this are contributing to a growing feeling on my part that Rails-style MVC may be a mistake for certain types of complex Web applications. The question is whether something better exists... :) Note also that I am *not* advocating breaking MVC while using Rails. > Another solution is the interlock plugin > http://blog.evanweaver.com/files/doc/fauna/interlock/files/README.html > although I haven't used that myself Nor have I.
