django-lucus 0.1.2

Lucus enhances Django Admin with custom templates, static theming, and a multi-column dashboard.

Lucus (Django Admin)

Read this in another language: Русский

Lucus restyles django.contrib.admin: a standalone admin base template, Lucus-owned static (including vendored admin structural CSS under lucus/static/), per-user color scheme + appearance, and a configurable multi-column dashboard on /admin/. The Django nav sidebar is disabled; change-form actions use a fixed bottom bar.

Requirements

• Python 3.10+
• Django 5.2+ (see package metadata: django>=5.2,<7)

Installation

pip install django-lucus

Package import name: lucus. PyPI project name: django-lucus.

Quick start

Add Lucus before django.contrib.admin so its templates win:

INSTALLED_APPS = [
    # ...
    "lucus",
    "django.contrib.admin",
    # ...
]

Templates and static files ship with the package; run collectstatic in production as usual.

After upgrading, run migrations so LucusAdminUiPreference exists:

python manage.py migrate lucus_admin

Settings reference

Setting	Type	Default	Description
SITE_NAME	str	"Site"	Used in LUCUS_ADMIN_SITE_HEADER_TEMPLATE and optionally as site_title
LUCUS_ADMIN_SITE_HEADER_TEMPLATE	str	"Administration — {site}"	Passed to str.format(site=SITE_NAME) for admin.site.site_header. Use only {site} unless you escape other braces.
LUCUS_ADMIN_SITE_TITLE_USE_SITE_NAME	bool	True	If True, admin.site.site_title = SITE_NAME
(none)	—	—	Color scheme is not a project setting: staff choose palette + appearance (light / dark / auto) from header dropdowns; choices are stored in LucusAdminUiPreference per user. Bundled palettes: olivia, grey, slate, dune, midnight (lucus/static/lucus/css/<slug>.css).
LUCUS_UI	dict	see below	Flags: help_as_icon, high_contrast_toggle (default True). Change-form save bar and changelist actions bar are fixed to the viewport bottom.
LUCUS_EXTRA_STATIC_CSS	str | list | tuple	()	Extra stylesheet paths (relative to static roots), loaded after the scheme. No .. or leading /.
LUCUS_EMPTY_VALUE_DISPLAY_WRAP	bool	True	Wrap empty changelist cells in <span class="lucus-admin-empty">
LUCUS_EMPTY_VALUE_PLACEHOLDER	str	"—"	Text for empty_value_display
LUCUS_ACTIONS_ON_BOTTOM	bool	True	Sets ModelAdmin.actions_on_bottom = True on the class (global for the process)
LUCUS_DASHBOARD	list | None	None	Dashboard config (see Dashboard); if unset, grouped defaults apply
LUCUS_DASHBOARD_APPEND_UNCOVERED	bool	True	In grouped mode: append apps not “covered” by groups into the last column

Theme context is built by lucus.theme.lucus_admin_extra_context(request) and merged in admin.site.each_context.

Dashboard: LUCUS_DASHBOARD

Lucus detects one of two shapes (lucus.dashboard: looks_like_dashboard_layout, looks_like_groups_config).

Template context: lucus_dashboard_columns — tuple[DashboardColumn, ...] from get_dashboard_for_request(request).

Links in a section can use:

• url — explicit URL
• admin_urlname — e.g. admin:app_model_changelist (resolved with reverse())

A section is shown only if at least one link resolves.

Mode 1: layout columns

List of dicts with classes and/or sections. Optional column in 1..4: multiple dicts with the same column are merged (sections concatenated; classes from the first dict for that column wins). Column index is clamped to 1–4.

Mode 2: column groups

List of dicts with:

• column (1-based, clamped to ≥ 1; practical grid 1–4)
• title — card heading
• links — optional list of {"label", "admin_urlname"|"url"}
• app_labels — optional set, frozenset, list, or tuple of app_label strings

Rules:

• Within a group, explicit links are listed first (in order), then models from app_labels. URLs are deduplicated.
• For list / tuple app_labels, app order follows that sequence; model order matches the admin.
• For set / frozenset, app order follows get_app_list.

Uncovered apps: if LUCUS_DASHBOARD_APPEND_UNCOVERED is True, apps not in the “covered” set are appended to the last column. Covered includes every app_label mentioned in groups and apps inferred from successful admin_urlname values in links (pattern admin:<app>_<model>_changelist, longest app_label match wins). Set to False if you want only the groups you defined, with no extra column of leftovers.

Examples

Layout with explicit columns:

LUCUS_DASHBOARD = [
    {
        "column": 1,
        "classes": "lucus-dashboard__col lucus-col lucus-col-3 lucus-col-md-6 lucus-col-sm-12",
        "sections": [
            {
                "title": "Education",
                "links": [
                    {"label": "Instructors", "admin_urlname": "admin:academy_instructor_changelist"},
                    {"label": "Courses", "url": "/admin/academy/course/"},
                ],
            },
        ],
    },
]

Groups with app_labels:

LUCUS_DASHBOARD = [
    {"column": 1, "title": "Authorization", "app_labels": {"auth"}},
]

Mixed links + app_labels:

LUCUS_DASHBOARD = [
    {
        "column": 2,
        "title": "Auth",
        "links": [
            {"label": "Users", "admin_urlname": "admin:auth_user_changelist"},
        ],
        "app_labels": ("auth",),
    },
]

Templates and static files

templates/admin/base.html is Lucus-owned. CSS load order: lucus/css/style.css (layout/tokens), lucus/css/lucus-admin.css (single admin UI sheet shipped with the package — no django.contrib.admin <link>), then the palette (lucus/css/<slug>.css, overrides tokens), then optional LUCUS_EXTRA_STATIC_CSS.

Admin JavaScript still comes from django.contrib.admin (admin/js/…) for widgets, inlines, and actions.

Bundled palettes (extend by shipping static/lucus/css/<slug>.css and forking lucus.theme.BUNDLED_COLOR_SCHEMES in your project if needed):

File	Role
style.css	Spacing scale, grid, UI; accents via var(--lucus-accent) etc.
olivia.css	Default green-gray palette
grey.css	Blue-gray palette
slate.css	Neutral slate
dune.css	Warm sand
midnight.css	Dark / light pairing

Package layout

Module	Role
lucus.apps.LucusConfig	ready(): site headers, each_context, dashboard, theme prefs URL, enable_nav_sidebar = False, empty_value_display, actions_on_bottom
lucus.dashboard	Config normalization, columns, links
lucus.models	LucusAdminUiPreference (per-user scheme + appearance)
lucus.theme	Bundled schemes, lucus_admin_extra_context(request)
lucus.views	POST handler for saving UI preferences

Version: lucus.__version__ (kept in sync with package metadata on release).

Compatibility

Lucus targets Django 5.2+ and is tested against the supported 5.x / 6.x line per pyproject.toml.
