Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.4.1]

Fixed

  • Plain Python packages now appear in the live debug view (/__depmap__/) as well as the management command output. Switched _discover_plain_packages from importlib.import_module to importlib.util.find_spec so discovery no longer executes the package's __init__.py; this avoids import-time exceptions (e.g. AppRegistryNotReady, circular imports) that silently suppressed discovery in a web-request context.
  • Namespace packages (no __init__.py) are now supported as root packages via spec.submodule_search_locations.
  • Broadened exception handling in plain-package discovery so a single broken root package can no longer null out the whole app_map via the outer except Exception in _run_analysis.

Added

  • Diagnostic warnings emitted once per process when a plain package can't be resolved (bad import, missing spec, or no source location) — helps future users diagnose configuration issues without log spam.

[0.4.0] - 2026-04-17

Added

  • Support for plain Python packages in DEPENDENCY_MAP_ROOT_PACKAGES. Subpackages of a non-Django root package are auto-discovered and added as nodes alongside Django apps; flat packages become a single node. Django app internals (migrations/, management/, templatetags/, locale/) and subpackages of registered Django apps are excluded.

[0.3.3] - 2026-04-13

Fixed

  • Regression in the display of third-party packages. Abstract-base-model nodes that appeared in foreign clusters are now skipped outright rather than reattributed, which was causing inherited FKs (e.g. created_by) to be incorrectly drawn between apps. Inheritance edges were already suppressed by edge classification.

[0.3.2] - 2026-04-13

Duplicate release tag — points at the same commit as 0.3.1 (tagging mistake). No changes.

[0.3.1] - 2026-04-13

Fixed

  • Abstract models causing spurious dependency cycles. graph_models --group-models duplicates abstract-base nodes into every cluster that inherits from them; the parser now detects foreign nodes via the node-ID prefix and resolves them to the true owning app instead of attributing FKs to each inheriting app.

[0.3.0] - 2026-04-10

Added

  • Import-linter contract rule export. New "Rules" tab in the export panel generates ready-to-paste .importlinter contract rules from the currently visible graph.
  • Root packages are now threaded through to the renderer and DjDT panel so exported rules reference the correct top-level package names.

Changed

  • Export panel redesigned from modal dialog to bottom-docked drawer for better visibility while inspecting the graph.

[0.2.0] - 2026-04-09

Added

  • Model relationship classification: FK, O2O, M2M, and generic relations are now distinguished in the model-edge type, parsed from DOT arrow attributes via _classify_dot_edge.
  • Per-edge import_count so edge thickness / tooltips can reflect import frequency.
  • Cycle-break suggestions via grimp.nominate_cycle_breakers(). Suggested edges are surfaced both in the graph (is_break_suggestion flag) and as a structured list in the serialized output.
  • Inheritance edges are now filtered out of the model graph — grimp already covers these via imports, so including them double-counts.

Changed

  • Edge parser rewritten to capture the full attribute string, enabling downstream edge classification.

[0.1.0] - 2025-04-07

Added

  • dependency_map management command with --open, --format, --output, --check flags
  • Model-level FK/M2M relationship extraction via graph_models (django-extensions)
  • Import graph analysis via grimp
  • Unified app-level graph merging both sources with coupling classification (fk, import, both)
  • Interactive D3 v7 force-directed HTML visualisation (self-contained, no server required)
  • Edge colour coding: FK (blue), import (green, dashed), both (purple), violation (red), cycle (orange)
  • Node sizing proportional to model count
  • Side panel: model list, instability metric, afferent/efferent coupling, dependency list
  • Edge tooltip: model-level FK pairs and field names
  • Filter buttons to toggle edge types independently
  • .importlinter / setup.cfg contract auto-parsing (layers, independence, forbidden)
  • Cycle detection via Tarjan's SCC algorithm
  • Cycle visualisation: orange node halos, orange cycle edges, cycle panel section
  • --check CI mode: structured stderr report, exits 1 on violations or cycles
  • --no-importlinter flag to skip contract auto-loading
  • --violation SRC:TGT flag for manual violation pairs
  • --root-package flag (repeatable) for monorepo support
  • JSON output mode (--format json)
