django group by
The Django ORM provides a values()
method that works similarly to SQL’s GROUP BY
clause. This method returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterator.
The annotate()
method is used to perform the equivalent of a SQL GROUP BY
query. It allows us to generate summary values based on a set of objects.
The aggregate()
method is used to perform the equivalent of a SQL GROUP BY
query. It allows us to generate summary values based on a set of objects.
