able to return nested dictionary using values? django

Question

let's say if I have a model named Blog and this is how the value works

>>> Blog.objects.values()
[{'id': 1, 'name': 'Beatles Blog', 'tagline': 'All the latest Beatles news.'}],
>>> Blog.objects.values('id', 'name')
[{'id': 1, 'name': 'Beatles Blog'}]

but let's say if I want to make the name into another dict and get such in return

[{'id': 1, 'blog': { 'name': 'Beatles Blog'}}]

is the above possible by using value or something similiar?

I know I can do something like which would work

[{'id': blog.pk, 'blog': {'name': blog.name}} for blog in blogs]

Thanks in advance for my curiosity

Answer 1

This is not possible using values.

The method you suggested works well.

If you have a lot of extra fields on your model, and only need those two, a performance improvement would be to first load just the fields you need using values, then perform the list comprehension on them to reformat it as you specified.

This avoids unnecessarily querying the database for fields you do not need.
