I've been trying to get gmaps4rails working for hours. I think it's the load order, I even tried cloning a demo app using rails 3.2 and ruby 1.9.3-- still showing a blank map with no markers. My JSON is correct from the model.

Sorry to read you wasted time: it's not the purpose of my gem :)
I don't see yield :scripts in your layout. It's one of the mandatory prerequisites stated in the project's homepage.
