Does Rails' fragment caching suit this problem?

Question

I do not understand yet Rails' caching system, but I've read in the guides section of a feature called fragment caching.

My problem is: my view consist mostly in static elements. It is almost completely static, the only changing is a status message and a hidden input field in a form, both generated at every request to the action serving the view.

Is fragment caching suitable for this problem? What caching strategy should I use?
