It extends Django querysets with methods to add computed columns (tree_depth, tree_path, tree_ordering) and control sibling ordering. The package supports PostgreSQL, SQLite (3.8.3 or higher), MySQL (8.0 or higher), and MariaDB (10.2.2 or higher), with automatic optimization for simple queries that avoids creating intermediate rank tables.\n\nThe library enforces a minimal design: parent foreign keys must be named \"parent\", primary keys must be integer or UUID, and tree depth is correctly defined with root nodes at depth zero. It includes an abstract model class with built-in loop protection and a variant for automatic sibling position management. The approach trades configurability for simplicity and performance, avoiding the complexity and data redundancy of other tree libraries.","worth_installing":"Yes. The package is actively maintained, has no security vulnerabilities, installs with zero dependencies, and solves a real problem with a clean, opinionated design. It is suitable for any Django project needing hierarchical data queries on supported databases. The 50-level limit on MySQL/MariaDB is a documented trade-off; verify it fits your use case before committing."},"id":"django-tree-queries","links":{"html":"https://skillfed.io/packages/django-tree-queries","md":"https://skillfed.io/packages/django-tree-queries.md","pypi":"https://pypi.org/project/django-tree-queries/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-03-25","license_spdx":null,"license_treatment":"permissive","name":"django-tree-queries","python_support":"supports_current","summary":"Tree queries with explicit opt-in, without configurability"},"popularity":{"monthly_downloads":236026,"position":8991,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.24.0"}
