select_related() will help you boost performance for retrieving related objects in one-to-many relationships. However, select_related() cannot work for many-to-many or many-to-one relationships (ManyToMany or reverse ForeignKey fields). Django offers a different QuerySet method called prefetch_related that works for many-to-many and many-to-one relations in addition to the relations supported by select_related(). The prefetch_related() method performs a separate lookup for each relationship and joins the results using Python. This method also supports the prefetching of GenericRelation and GenericForeignKey.
