# Returns the result of a render that's dictated by the options hash. The primary options are:
|
|
#
|
|
# * <tt>:partial</tt> - See ActionView::Partials.
|
|
# * <tt>:update</tt> - Calls update_page with the block given.
|
|
# * <tt>:file</tt> - Renders an explicit template file (this used to be the old default), add :locals to pass in those.
|
|
# * <tt>:inline</tt> - Renders an inline template similar to how it's done in the controller.
|
|
# * <tt>:text</tt> - Renders the text passed in out.
|
|
#
|
|
# If no options hash is passed or :update specified, the default is to render a partial and use the second parameter
|
|
# as the locals hash.
