Hello,

Anybody please recommend me a best way how to implement a session cart.
My task is - i have a different models(for example
:Person,City,House,Car…).
Also i have per each model a list with button.
Finally i have web page where i need to display all selected models
grouped by type(model).

How to implement this? - Save a hash in session with selected model
id’s?

Thanks

That will do the trick. You definitely want to be storing model ids
rather than objects.
