📝 Walkthrough

Walkthrough

The changes implement robust foreign key handling across the admin interface by adding relationship introspection, type-aware value coercion, and improved choice discovery logic in filters, form engine, and query engine layers, alongside template fixes and comprehensive test coverage.

Changes

Cohort / File(s)	Summary
Foreign Key Filter & Form Engine internal_admin/admin/filters.py, internal_admin/admin/form_engine.py	Enhanced foreign key resolution with relationship introspection, dynamic choice discovery from related models, display label attribute selection (display_name, name, title, username, email), and result limiting to 200 items. Adds fallback mechanisms for missing related data.
Query Engine Type Coercion internal_admin/admin/query_engine.py	Introduces _coerce_filter_value() helper for type-aware value coercion. Handles SQLAlchemy type derivation (including TypeDecorator), converts values to Boolean, Integer, Float, Date, or DateTime, and integrates coercion into filter application logic.
Template Selection Fix internal_admin/templates/admin/form.html	Updates option selection comparison to coerce both current form value and option value to strings before equality check, resolving type mismatch issues in select fields.
Test Infrastructure tests/conftest.py, tests/test_admin.py	Adds TestCategory and TestProduct models with foreign key relationship, related admin configurations, and new test class TestForeignKeys with three tests covering FK choice rendering, relation persistence, and FK-based filtering.

Poem

🐰 Whiskers twitch with foreign key delight,
Relations discovered in the database night,
Types coerce to integers, dates align,
Select options sparkle, choices divine!
From form to filter, the logic flows true,
A rabbit's work here—efficient and new! 🥕
