Rails equivalent to symfony's admin generator?

Does Rails have an equivalent to the admin generator feature in symfony? The admin generator works similarly to scaffolding and basic crud generators but is much more advanced for generating admin interfaces and uses YAML files for configuration and more advanced features over just basic crud. I've only just started playing with rails and haven't yet seen anything like symfony's feature.
