Missing imports in "Expressions can reference transforms" section.

[Eido Askayo]

In section ​Expressions can reference transforms, the following code is shown:

>>> Entry.objects.aggregate(first_published_year=Min('pub_date__year'))

There is a missing import for Min function:

>>> from django.db.models import Min

Also, the following code is shown:

>>> Entry.objects.values('pub_date__year').annotate(
...     top_rating=Subquery(
...         Entry.objects.filter(
...             pub_date__year=OuterRef('pub_date__year')
...         ).order_by('-rating').values('rating')[:1]
...     ),
...     total_comments=Sum('number_of_comments'))

There are missing imports for Subquery, OuterRef and Sum functions:

>>> from django.db.models import Subquery, OuterRef, Sum
