--------------------------------------------+--------------------------
I often use JSONBAgg and when there are several aggregates, contains
duplicates.
{{{
class Author(models.Model):
name = models.CharField(max_length=50)
alias = models.CharField(max_length=50, null=True, blank=True)
age = models.PositiveSmallIntegerField(default=30)
class Article(models.Model):
authors = models.ManyToManyField(Author, related_name='articles')
title = models.CharField(max_length=50)
class Product(models.Model):
article = models.ForeignKey(Article, related_name='products',
on_delete=models.CASCADE)
name = models.CharField(max_length=255)
Article.objects.annotate(
authors_json=ArrayAgg(
Func(
Value('name'), 'authors__name',
Value('alias'), 'authors__alias',
function='jsonb_build_object'
),
distinct=True,
),
products_json=ArrayAgg(
Func(
Value('name'), 'products__name',
function='jsonb_build_object'
),
distinct=True,
),
)
}}}
