# 1. like in example above
await Car.objects.select_related('manufacturer').fields(['id', 'name', 'manufacturer__name']).all()
# 2. to mark a field as required use ellipsis
await Car.objects.select_related('manufacturer').fields({'id': ...,
'name': ...,
'manufacturer': {
'name': ...}
}).all()
# 3. to include whole nested model use ellipsis
await Car.objects.select_related('manufacturer').fields({'id': ...,
'name': ...,
'manufacturer': ...
}).all()
# 4. to specify fields at last nesting level you can also use set - equivalent to 2. above
await Car.objects.select_related('manufacturer').fields({'id': ...,
'name': ...,
'manufacturer': {'name'}
}).all()
# 5. of course set can have multiple fields
await Car.objects.select_related('manufacturer').fields({'id': ...,
'name': ...,
'manufacturer': {'name', 'founded'}
}).all()
# 6. you can include all nested fields but it will be equivalent of 3. above which is shorter
await Car.objects.select_related('manufacturer').fields({'id': ...,
'name': ...,
'manufacturer': {'id', 'name', 'founded'}
}).all()
