Installation

pip install --index-url https://git.helu.ca/api/packages/r/pypi/simple/ --extra-index-url https://pypi.org/simple django-heluca-themis

About this package

Django app providing user preferences, theme management, API key management, Casdoor SSO adapters, and standard navigation templates

Themis

Reusable Django app providing user preferences, DaisyUI theme management, API key management, and standard navigation templates for all Heluca applications.

Themis — titan of order, custom, and law.

Features

  • User Preferences — timezone (home + traveling), date/time/number formatting, week start day
  • Heluca Design System — the V2 system vendored from @heluca/svelte: token layer + daisyUI 5 bridge, light / dark plus the five temperaments (consulting, business, business-dark, terminal, terminal-light), self-hosted Marcellus, Literata, Public Sans, IBM Plex Sans, JetBrains Mono and Atkinson Hyperlegible; separate light/dark selection, auto (system) mode
  • Notifications — in-app notification bell, JS polling, browser desktop notifications, user preferences
  • API Key Management — encrypted storage with per-key instructions and documentation links
  • Standard Navigation — consistent navbar, user menu, notification bell, theme toggle, and bottom nav across all apps
  • Themed Auth Pages — every django-allauth page (login, signup, logout, password reset/change, email management, …) rendered in the Themis DaisyUI chrome, with no per-app templates
  • Middleware — automatic timezone activation and theme context
  • Formatting Utilities — date, time, number formatting respecting user preferences
  • Health Checks — Kubernetes-ready /ready/ and /live/ endpoints
  • REST API — complete API for profiles, keys, and notifications

Installation

pip install git+ssh://git@git.helu.ca:22022/r/themis.git

Quick Start

  1. Add to INSTALLED_APPS:
INSTALLED_APPS = [
    ...
    "rest_framework",
    "themis",
    ...
]
  1. Configure middleware:
MIDDLEWARE = [
    ...
    "themis.middleware.TimezoneMiddleware",
    "themis.middleware.ThemeMiddleware",
    ...
]
  1. Configure context processors:
TEMPLATES = [{
    "OPTIONS": {
        "context_processors": [
            ...
            "themis.context_processors.themis_settings",
            "themis.context_processors.user_preferences",
            "themis.context_processors.notifications",
            "themis.context_processors.navigation",
        ],
    },
}]
  1. Include URLs:
urlpatterns = [
    ...
    path("", include("themis.urls")),
    path("api/v1/", include("themis.api.urls")),
    ...
]
  1. Configure app settings:
THEMIS_APP_NAME = "My Application"

# Register navigation entries (block-based extension can't cross {% include %},
# so the chrome iterates these instead). Each entry: label, named URL, optional
# SVG icon `d` path. Bad url_names are skipped with a warning, not a 500.
THEMIS_NAV_ITEMS = [
    {"label": "Home", "url_name": "core:home"},
    {"label": "Mail", "url_name": "mail:account_list"},
]
THEMIS_USER_MENU_ITEMS = [
    {"label": "Mail Accounts", "url_name": "mail:account_list"},
]
  1. Run migrations:
python manage.py migrate
  1. Extend the base template:
{% extends "themis/base.html" %}

{% block nav_items %}
<li><a href="{% url 'dashboard' %}">Dashboard</a></li>
{% endblock %}

{% block content %}
<h1 class="text-2xl font-bold">My App</h1>
{% endblock %}

Casdoor SSO (optional)

Themis ships generic django-allauth adapters for Casdoor OIDC. They map the Casdoor groups claim to Django groups, set is_staff from configurable staff groups, and block superusers from SSO (they must use local auth).

SOCIALACCOUNT_ADAPTER = "themis.adapters.CasdoorAccountAdapter"
ACCOUNT_ADAPTER = "themis.adapters.LocalAccountAdapter"

Optional settings:

  • THEMIS_STAFF_GROUPS — Casdoor groups granting is_staff (default ["staff", "sme", "admin"]).
  • THEMIS_GROUP_MAPPING — Casdoor group name → Django group name.
  • THEMIS_ORG_ADAPTER — dotted path to fn(user, org_identifier) invoked with the Casdoor organization claim, for apps with an Organization model. Omit it (the default) to skip organization mapping.
  • THEMIS_TENANT_ADAPTER — store mode (Agora ADR-0004): dotted path to fn(user, tenant_id, groups) invoked with the tenant_id claim and the bare own-org group names, instead of the org adapter, whenever the claim is present. Helpers for the projected groups live in themis.tenancy.
  • THEMIS_REQUIRED_GROUP_PREFIX — a product slug; an SSO login holding no <prefix> / <prefix>-* group is refused before provisioning and sent to themis:no-subscription, which links to THEMIS_STORE_URL (required with the prefix; system check themis.E001). See docs/Pattern_SaaS-Tenancy_V1-01.md § Store mode.
  • THEMIS_PROFILE_SOURCE — "local" (default) keeps preferences on the app's own settings page; "claims" links the app to the estate's Agora (ADR-0018): the projected preference claims (timezone, date_format, theme_mode, …) are copied into UserProfile at every login — a missing claim leaves its field alone — and the settings page turns read-only with a "Manage in Agora" link to {AGORA_URL}/profile/. AGORA_URL is required with "claims" (system check themis.E002; environment value, no default). See docs/Pattern_SSO-Allauth-Casdoor_V1-04.md § Profile Claims.
  • AGORA_URL, AGORA_PRODUCT_API_KEY — the entitlements client (themis.entitlements: get_limits, check_quota, quota_blocked, report_usage, flush_usage). Both from the environment, no defaults, set together (system check themis.E004); the usage PUT is named by THEMIS_REQUIRED_GROUP_PREFIX (themis.E005). Optional: THEMIS_TENANT_RESOLVER (dotted path fn(request) -> tenant id; default reads request.tenant.uuid), THEMIS_QUOTA_WARN_RATIO (0.8). Add themis.context_processors.entitlements for the warn banner and schedule manage.py flush_usage every minute. See docs/Pattern_Entitlements_V1-00.md.

Reconnecting an account after an IdP reset

OIDC matches a returning user on the subject id allauth stored as SocialAccount.uid — for Casdoor, the user's id. Re-provisioning Casdoor re-issues those ids, so every stored connection is orphaned and SSO login falls through to auto-signup. Re-point it:

# Preview the change (old -> new uid), write nothing
python manage.py reconnect_socialaccount user@example.com --uid <new-casdoor-id> --dry-run

python manage.py reconnect_socialaccount user@example.com --uid <new-casdoor-id>

Resolves the user by username or email, creates the connection when none exists, no-ops when the uid already matches, and refuses when that uid belongs to another user. --provider defaults to casdoor — the provider_id allauth stores, not openid_connect. Full procedure, including how to do it without this command: SSO with Allauth & Casdoor.

For sandbox environments with self-signed Casdoor certs, import the SSL bypass at the top of settings.py before any requests are made (activates only when CASDOOR_SSL_VERIFY=false):

import themis.ssl_patch  # noqa: F401
