why not use this simple line in one single method instead of that confusing way to access doc and model! #190
Description
reviewSchema.post(/^findOneAnd/, async function (doc) {
await this.model.calcAverageRatings(doc.tour);instead of
reviewSchema.pre(/^findOneAnd/, async function(next) {
this.r = await this.findOne();
// console.log(this.r);
next();
});
reviewSchema.post(/^findOneAnd/, async function() {
// await this.findOne(); does NOT work here, query has already executed
await this.r.constructor.calcAverageRatings(this.r.tour);
