We have a helper function that fetches data and does some computations. This helper is used mostly everywhere. We have now come to the phase of optimization and come to the conclusion that some caching will help speed things up. I good place to get a lot of bang for a small investment would be to make use of the fragment caching in Rails and we would like to utilize it in this function in order to avoid to have to add the cache call everywhere.
Having looked at the code for ActionView#cache and ActionController#cache_erb_fragment it seems that a block from the erb template is needed. The problem is that we don't have a block from the template available in the helper function (without changing in the function call in all templates...). Is there another way to get at the caching functionality without having to re-write it ourselves?
