.. admonition:: Interaction with prefetching
|
||||
|
||||
When calling :meth:`~django.db.models.query.QuerySet.prefetch_related` with
|
||||
a reverse relation, the default manager will be used. If you want to
|
||||
prefetch related objects using a custom reverse manager, use
|
||||
:class:`Prefetch() <django.db.models.Prefetch>`. For example::
|
||||
|
||||
from django.db.models import Prefetch
|
||||
|
||||
prefetch_manager = Prefetch("entry_set", queryset=Entry.entries.all())
|
||||
Blog.objects.prefetch_related(prefetch_manager)
