Why there is some DB interaction during the View rendering? You dont need to do any query "explicitly" on the View file, if you are calling a method that does some DB interaction you are doing a Query during the View Context. If you need some data that comes from model (doesn't matter if it is from DB or not), do it on the controller, setting variables to output them on the View.
Can someone confirm my conclusion?
