Your example is sparse to the point of being a tad obtuse, but I think I get
what you're asking.
Unless you reference modelTemp directly from inside exe1, you don't need to
import it. If exe1 had a foreignKey to modelTemp, you'd need to import
modelTemp. Otherwise, you don't.

In the view you would need to check if the voter has already voted in

if the query contains a record for a particular poll and a particular
