nested resources and collection


I'm not 100% sure but I think it's because you have name_prefix set to
"admin_", so the it would be "admin_checked_images_path". Give that a
try and let us know if that works.

Yes that's it! I just got the same problem yesterday!

So, with that parameter, your are only able to administer checked
images related to a gallery at a time, isn't it?
Have you found a cool way to administer all of them at a time, keeping
a pretty RESTful design?
