Instance Method Details

#cobranding_layout(url_or_layout, options = nil, &block) ⇒ Object

Helper method to render a layout. The url_or_layout can either be a URL to a layout service or a Layout object. The options parameter will only be used if a URL is passed in.

This method can take a block which should be a fail safe ERB version of the layout that will only be used if the layout service is unavailable.

Note that for Rails 2.x applications you must call the tag with a block as <% cobranding_layout do %> while in Rails 3.0 and later you must call it as <%= cobranding_layout do %>.
