Development helpers

This package is a sandbox and reference implementation for Ex-DRF (Extended Datasets–Resources–Fields) in the same monorepo as exdrf. It is not a minimal runtime dependency for applications that only use the core library; instead it collects runnable examples, Qt UIs, and tooling that exercise Ex-DRF and related packages end to end.

What lives here

• Sample domain models under exdrf_dev/db/: SQLAlchemy entities with relationships (parents, children, tags, profiles, composite keys, related items, and association tables). They illustrate typical metadata and typing patterns used with Ex-DRF and exdrf_al.
• Qt examples: hand-written widgets under exdrf_dev/qt/ plus generated scaffolding under exdrf_dev/qt_gen/ and exdrf_dev/attr_gen/, showing how generated and custom pieces fit together for desktop UIs (PyQt5).
• Command-line helpers in exdrf_dev/cli.py: a Click group that loads .env, can print the environment, runs arbitrary subprocess commands (with optional env:VAR indirection), and reuses exdrf_al migration commands (upgrade, downgrade, list/set versions, auto migration).

Dependencies and audience

Install exdrf-dev when you need the demo app, Qt samples, or CLI shortcuts above. It depends on exdrf (core) and declares PyQt5, click, and python-dotenv. Optional dev extras in pyproject.toml cover formatters, linters, pytest, and factories for local quality work.

Tests and monorepo runs

The helper module exdrf_dev/pytest_dirs.py runs pytest across several package directories with a shared PYTHONPATH layout; the root Makefile references exdrf_dev.pytest_dirs when driving multi-package test runs in this repo.
