feat(master-detail): live Subtotal / Tax / Total stack by xuyushun441-sys · Pull Request #1567 · objectstack-ai/objectui

xuyushun441-sys · 2026-06-07T08:24:15Z

Why

The last P1 item for the line-item editor: the right-aligned Subtotal / Tax / Total block every invoicing tool shows, computed live during entry.

What

MasterDetailForm renders a document totals stack under the line items when the parent form has a tax-rate field (taxRateField, default tax_rate):

Subtotal = Σ line amounts
Tax = Subtotal × header rate %
Total = Subtotal + Tax

The header rate is read live via scoped event delegation on the existing form host (formHostRef) — no coupling into ObjectForm/FormSchema internals. When the stack is shown, the per-grid footer total is subsumed. The stack only appears when the tax-rate field is present, so other master-detail forms (e.g. project + tasks) are unaffected.

Verification

Unit: MasterDetailForm tests pass.
Live e2e: New Invoice → pick Widget A, Qty 2, Tax Rate 10 → Subtotal ¥59.98 / Tax (10%) ¥6.00 / Total ¥65.98.
Browser-verified (Gadget X × 2 @ 99 + 10% → ¥217.80).

Pairs with framework#1640 (the showcase_invoice.tax_rate field). The live backend already serves it.

🤖 Generated with Claude Code

When the parent form has a tax-rate field (taxRateField, default 'tax_rate'), MasterDetailForm renders a right-aligned totals stack below the line items — Subtotal (Σ line amounts) → Tax (header rate %) → Total — recomputed live as lines and the rate change. The rate is read via scoped event delegation on the form host (no coupling into ObjectForm internals); the per-grid footer total is subsumed when the stack shows. Live e2e asserts the stack on New Invoice. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
