How to annotate more than one value in Django

Question

I want to expand existing queryset.

I tried the following:

def queryset(self, request):
    qs = super(MyAdmin, self).queryset(request)
    qs = qs.annotate(models.Count('article'))
    return qs

It works perfectly for one annotation. But how can I add more?

def queryset(self, request):
    qs = super(MyAdmin, self).queryset(request)
    qs = qs.annotate(models.Count('article'))
    qs = qs.annotate(models.Count('comment'))
    return qs

With above solution results go crazy. When it should show:

• 2 articles
• 2 comments

it shows:

• 4 articles
• 4 comments

Answer 1

you should use this

Count('article', distinct=True)

def queryset(self, request):
    qs = super(MyAdmin, self).queryset(request)
    qs = qs.annotate(models.Count('article', distinct=True))
    qs = qs.annotate(models.Count('comments', distinct=True))
    return qs
