feat(master-detail): derive child columns + FK from metadata by xuyushun441-sys · Pull Request #1526 · objectstack-ai/objectui

xuyushun441-sys · 2026-06-06T11:34:25Z

Summary

Answers "do master-detail forms really need a hand-authored columns block?" — no. A child collection can now be configured with just the child object name; the relationship FK and editable grid columns are derived from the child object's metadata.

// before — ~40 lines
details: [{childObject: 'showcase_task',relationshipField: 'project',columns: [/* 12+ lines */]}]// after
details: [{childObject: 'showcase_task'}]

What it does

relationshipField auto-detected from the child's master_detail/lookup field whose reference is the parent (master_detail preferred).
columns derived from the child's fields — skips system/audit fields, the back-reference FK, and non-editable types (formula/summary/autonumber/file/json/…); select options and lookup reference/displayField carry through; types mapped to grid column types.
amountField (running-total source) defaults to the first numeric/currency column.
All of these remain explicitly overridable.
MasterDetailForm resolves unconfigured details via getObjectSchema and gates Save until resolved.

Testing

New pure helpers deriveDetail / deriveColumns / findRelationshipField + fieldTypeToColumnType — 9 unit tests (76 plugin-form pass).
Live e2e (2/2): the showcase form now derives its task columns at runtime and still posts the correct atomic /api/v1/batch (parent + child {$ref:0}). Paired showcase simplification in the framework repo drops its details block to one line.

A master-detail child collection can be configured with just { childObject }. The relationship FK is auto-detected from the child's master_detail/lookup field referencing the parent, and grid columns are derived from the child object schema (skipping system/audit/FK/non-editable fields; select options + lookup refs carried through). amountField defaults to the first numeric column. Explicit relationshipField/columns still override. New pure helpers deriveDetail/deriveColumns/findRelationshipField (+9 unit tests, 76 plugin-form pass). MasterDetailForm resolves unconfigured details via getObjectSchema and gates Save until resolved. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
