I know that in general it is a "good idea" to move logic out of templates and into helpers when possible.
For example, you could create a helper (either in the particular controller's helper file or in the application's helper file). Your helper might be called "show_div" and it might accept the thing you want to display as a parameter.
The helper would then test whether or not the object is empty and display your output when the object is not empty.
Let me know if that is not enough detail. I can provide a working example.
In any case, that's what I have been doing in cases like this. There may be other ways too. I'm looking forward to seeing what others suggest.
