RESTful design with multiple model types on one page

I have a nice RESTful design with separate pages for viewing and modifying my models in the conventional RESTful way. I now wish to provide a web page with several panels where each panel is showing data for a different model type. Data entered in one panel will change the objects shown in another. I am not sure of the best way to impliment this. Should I have an independant controller (with no model of it’s own) to manage this, which obtains data from the various models and renders it’s view, using partials to display the panels? Is there a better way?

I am sure this has been answered many times before but I have not seen the problem identified in discussions of REST that I have found, and I have not managed to formulate a google search to provide the answer.

Any suggestions would be much appreciated.

you can use the same controller to do this. just use partials for different models. Are the models associated? if yes, then it may be a bit complex. if not, then it would be quite easy. as for observing the changes, you could use the observe_field method of prototypehelper
