DjangoInlineField

Use django.DjangoInlineField to edit child rows inside the parent form.

from brilliance_admin import django


class ChildSchema(django.DjangoFieldsSchema):
    model = Child


class ParentSchema(django.DjangoFieldsSchema):
    model = Parent

    children = django.DjangoInlineField(
        label='Children',
        many=True,
        table_schema=ChildSchema(),
    )

How to add:

1. Create child DjangoFieldsSchema.
2. Add DjangoInlineField(..., table_schema=ChildSchema()).
3. Use parent schema in DjangoAdmin.

Parameter	Description
many	Must be True for reverse relation rows
table_schema	Child DjangoFieldsSchema
select_related	FK eager loading for child rows
prefetch_related	Prefetch eager loading for child rows
get_queryset	Custom child queryset builder

Queryset

DjangoInlineField loads child rows from the parent relation.

Use select_related and prefetch_related to eager-load fields:

children = django.DjangoInlineField(
    many=True,
    table_schema=ChildSchema(),
    select_related=['target', 'target__bank'],
    prefetch_related=['tags'],
)

For custom loading, pass get_queryset. It can be async and must return Django QuerySet:

async def get_children_queryset(relation, extra):
    return (
        relation.all()
        .select_related('target')
        .prefetch_related('tags')
        .order_by('id')
    )


children = django.DjangoInlineField(
    many=True,
    table_schema=ChildSchema(),
    get_queryset=get_children_queryset,
)

relation is the Django related manager from the parent record. extra contains the current parent record, user, and debug. If get_queryset is set, select_related and prefetch_related are not applied automatically. If an inline row __str__ or related field reads FK data, load it here.

How to use:

• rows are edited inside parent form
• create/update saves inline rows together with parent
• removed rows are deleted on save
• reverse FK to parent is removed automatically
• nested inline is not supported
