Detailed Description

Rating information is used to describe how good a place is conceived to be. Typically this information is visualized as a number of stars. The average() function returns an aggregated ratings value out of a possible maximum as given by the maximum() function.

qDebug() << QString("This place rated ") + place.ratings().average()
            + "out of " + place.ratings().maximum() + "stars";
