xladmin 0.3.6

Generic FastAPI + SQLAlchemy admin backend.

xladmin backend

xladmin-backend is the backend package published to PyPI as xladmin.

Important:

• package name on PyPI: xladmin
• Python import: from xladmin import ...
• monorepo: Artasov/xladmin

Public API

• AdminConfig / ModelConfig / FieldConfig
• ListFilterConfig
• BulkActionConfig / ObjectActionConfig
• ModelsBlock
• HttpConfig
• create_router(...)

Compatibility aliases are kept:

• Admin* config names
• create_admin_router(...)

Minimal Example

from xladmin import AdminConfig, HttpConfig, ModelConfig, create_router

from src.core.auth.dependencies import get_current_user
from src.core.db.session import get_db_session
from src.modules.identity.models import UserORM


config = AdminConfig(
    models=(
        ModelConfig(model=UserORM),
    ),
)

router = create_router(
    HttpConfig(
        registry=config,
        get_db_session_dependency=get_db_session,
        get_current_user_dependency=get_current_user,
        is_allowed=lambda user: bool(user.is_staff),
    ),
)

ModelConfig(model=UserORM) is enough for a basic admin. The library derives default slug, title, search fields, and ordering from the ORM model.

Features

• list / detail / create / patch / delete endpoints
• bulk actions and object actions
• relation choices and relation filters
• overview metadata and model blocks
• query_for_list and custom search_query_builder
• mode-specific form fields with hidden_in_create / hidden_in_update
• custom create defaults with create_item_factory
• delete preview for single and bulk delete
• RU / EN locale metadata for the frontend

Create And Update Fields

If a field should be visible only in one form mode, use hidden_in_create or hidden_in_update.

from xladmin import FieldConfig, ModelConfig


ModelConfig(
    model=UserORM,
    fields={
        "password": FieldConfig(
            input_kind="password",
            hidden_in_update=True,
            value_setter=set_user_password,
        ),
        "new_password": FieldConfig(
            input_kind="password",
            hidden_in_create=True,
            value_getter=lambda _user: "",
            value_setter=set_user_password,
        ),
    },
)

If create requires hidden service fields, use create_item_factory.

from xladmin import ModelConfig


def create_admin_user(payload, session, user):
    del payload, session, user
    return UserORM(
        date_joined=AuthBase.now(),
        secret_key=AuthBase.generate_secret_key(),
    )


ModelConfig(
    model=UserORM,
    create_fields=("username", "email", "password"),
    create_item_factory=create_admin_user,
)
