Instance Method Details

#block_to_partial(partial_name, options = {}, &block) ⇒ Object

Only need this helper once, it will provide an interface to convert a block into a partial.

  1. Capture is a Rails helper which will ‘capture’ the output of a block into a variable

  2. Merge the ‘body’ variable into our options hash

  3. Render the partial with the given options hash. Just like calling the partial directly.
