Blocks is a replacement / complement to content_for with yield. It allows a user to specify a block capable of taking parameters that may be passed in when using that block. A user may also specify other blocks to be prepended or appended before or after a specific block is rendered. A template may also be specified to blocks that will provide the layout for a specific component and provide default implementations for its blocks. In this way, blocks is able to offer a very simple to use table generator (table_for) and list generator (list_for).
