Deprecation Warning

I recently created a small app that searches a db and displays the
search results. I then cloned the app, changed the model and started
the clone up. The second app is Throwing out Deprecation warnings on
@params. I understand that params should be used instead, what I am
wondering however is why doesn’t the first app throw the Deprecation
Warning. I can find no differences between the two.

Any suggestions.

Thanks,
Lewis
