PATCH is the correct HTML verb to map to the #update action. The semantics for PATCH allows for partial updates, whereas PUT requires a complete replacement. Changes: * adds config.default_method_for_update you can set to :patch * optionally use PATCH instead of PUT in resource routes and forms * adds the #patch verb to routes to detect PATCH requests * adds #patch? to Request * changes documentation and comments to indicate support for PATCH This change maintains complete backwards compatibility by keeping :put as the default for config.default_method_for_update.
