📋 Decision Context
Question:
How to handle complex object updates in Angular templates without spread operators?
Task: Session 57.3: Fix Angular template compilation errors
🎯 Decision Made
Chosen:
Create dedicated helper methods for nested property updates (e.g., updateModuleRefModuleId, updateModuleRefCollection)
Options Considered:
- Use spread operator inline (fails in templates)
- Create helper methods in component
- Use ngModel two-way binding
💭 Reasoning
Angular templates don't support JavaScript spread operators (...) in expressions. Rather than complex workarounds, creating explicit helper methods improves readability, enables type checking, and follows Angular best practices. Each method handles one specific nested update, keeping the template clean while the TypeScript handles the complexity.
