Generic tasks and kanban boards for the Stapel framework

stapel-tasks

Generic tasks and kanban boards for the Stapel framework — composable Django apps that deploy as a monolith or as microservices without changing module code.

A generic task domain — Board / Column / Task / ChecklistItem / TaskComment, a REST surface, a full outbox event surface, and custom fields via stapel-attributes. It is useful to any project by itself (a team runs a board by hand), and it is the substrate an orchestrator projects onto: an external state machine drives cards through opaque origin_* handles and the MOVE_POLICY seam — the module knows nothing about the machine.

Install

pip install stapel-tasks              # core
pip install "stapel-tasks[attributes]"  # + typed custom-field validation

INSTALLED_APPS = [
    # ...
    "stapel_tasks",
]

# urls.py
path("tasks/", include("stapel_tasks.urls"))

Requires a stapel-core whose background taskstore app uses the label stapel_taskstore — this module owns the Django label stapel_tasks. See MODULE.md.

Concepts

• Board — an ordered set of columns and the cards on them. Owns the custom-field schema (feature_defs) and optional workflow settings.
• Column — a status. Its key is the card's status; its category (backlog/active/review/waiting/done) is the fixed machine semantic.
• Task (card) — status = its column; order within the column is a fractional position (drag-and-drop moves write one row). Custom-field values live in features; a projecting system writes origin_meta.
• Move — drag-and-drop is a move validated by MOVE_POLICY: allow / deny(reason_key) / defer (the managed-card path).

from stapel_tasks import services

board = services.create_board(name="Team", preset="simple")
card = services.create_task(board=board, title="Ship it")
services.move_task(card, to_column=board.columns.get(key="done"))  # emits task.completed

comm surface

Kind	Name	Purpose
Emit	task.created / task.updated / task.moved / task.assigned / task.completed / task.comment_added / task.checklist_item_changed / task.archived	Card lifecycle facts (via the outbox)
Consume	user.deleted	GDPR anonymization
Function	tasks.get / tasks.list_board / tasks.create / tasks.move / tasks.comment	Machine interface / MCP-tool candidates

Settings (STAPEL_TASKS)

Key	Default	What it customizes
SCOPE_PROVIDER	single global scope, allow-all	Tenancy resolution/filtering + permissions
MOVE_POLICY	allow any move (honours transitions)	Drag-and-drop authorization
BOARD_PRESETS	{} (merged over built-in simple)	Board-shape presets
STORE_UNKNOWN_FEATURES	True	Keep raw custom fields when attributes is absent
DEFAULT_PAGE_SIZE	100	Card-list page size
