Instance Method Details

#partial(partial_name) ⇒ Object

Include a partial. The method looks for a partial named as the argument and with extension .erb or .haml searching for it first in the current page directory, then in the current group directory and, finally, in the site directory. In other words, the partial which gets included is always the most specific one. If no partial with that name is found, an empty string is returned.
