What's this?

active_layout(passed_layout = nil) public

Returns the name of the active layout. If the layout was specified as a method reference (through a symbol), this method is called and the return value is used. Likewise if the layout was specified as an inline method (through a proc or method object). If the layout was defined without a directory, layouts is assumed. So layout "weblog/standard" will return weblog/standard, but layout "standard" will return layouts/standard.
