Work Log

2026-01-15

Visual Overhaul (schedule-view.tsx):
- Refactored the schedule grid to match the exact design of the ClassScheduleGrid widget.
- Implemented a clean, borderless layout with no grid lines for a modern look.
- Time-Based Positioning: Replaced grid-row logic with absolute positioning based on time (8:00 - 18:00 range) using percentage calculations (getPositionStyle).
- Color Coding: Added getSubjectColor to auto-assign thematic colors (blue for Math, purple for Physics, etc.) based on course names.
- Card Design: Refined course cards with vertical centering, better spacing, and removed unnecessary UI elements (like the "+" button in headers).
Filter Bar Refinement (schedule-filters.tsx):
- Minimalist Design: Removed borders and shadows from the class selector and buttons to integrate seamlessly with the background.
- Center Label: Added a dynamic, absolute-centered text label that updates based on selection:
  - Shows "All Classes" when no filter is active.
  - Shows "{Class Name}" when a specific class is selected.
- Simplified Controls: Removed the "Reset" button (X icon) entirely for a cleaner interface.
- Ghost Buttons: Styled the "Add Event" button as a ghost variant with muted colors.

Insights Module Removal:
- Deleted the entire src/app/(dashboard)/teacher/classes/insights directory as the feature was deemed redundant.
- Removed insights-filters.tsx component.
- Updated navigation.ts to remove the "Insights" link from the sidebar.
- Note: Preserved getClassHomeworkInsights in data-access.ts as it's still used by the Class Detail dashboard widgets.

Type Safety: Ran npm run typecheck multiple times during refactoring to ensure no regressions (Passed).
Build: Attempted to clear build cache to resolve a chunk loading error (Windows permission issue encountered but workaround applied).

Separation of Duties:
- Moved class creation and management responsibilities from the generic Teacher view to a dedicated Management view.
- Created Grade Management Page at src/app/(dashboard)/management/grade/classes/page.tsx for Grade Directors and Admins.
- Teachers can now only Join Classes (via code) or view their assigned classes in "My Classes".
New Components & Pages:
- GradeClassesView (src/modules/classes/components/grade-classes-view.tsx): A comprehensive table view for managing classes within specific grades, supporting creation, editing, and deletion.
- GradeClassesPage: Server Component that fetches managed grades and classes using strict RBAC (Role-Based Access Control).
Teacher "My Classes" Update (my-classes-grid.tsx):
- Removed the "Create Class" button/dialog.
- Added a "Join Class" dialog that accepts a 6-digit invitation code.
- Updated styling to use standard design system colors (bg-card, border-border) instead of hardcoded gradients.

Data Access (data-access.ts):
- Implemented getGradeManagedClasses: Fetches classes for grades where the user is either a Grade Head or Teaching Head.
- Implemented getManagedGrades: Fetches the list of grades managed by the user for the creation dropdown.
- Updated getTeacherClasses: Now returns both owned classes (assigned by admin) and enrolled classes (joined via code).
- Fixed a SQL syntax error in getGradeManagedClasses (unescaped backticks in template literal).
Server Actions (actions.ts):
- Added createGradeClassAction, updateGradeClassAction, deleteGradeClassAction: These actions enforce that the user manages the target grade before performing operations.
- Updated joinClassByInvitationCodeAction: Expanded to allow Teachers (role teacher) to join classes, not just Students.

RBAC: Verified that users can only manage classes for grades they are assigned to.
Flow: Verified Teacher "Join Class" flow correctly redirects and updates the list.
Syntax: Fixed TypeScript/SQL syntax errors in the new data access functions.

Students Management Interface (students-table.tsx, students-filters.tsx):
- Enhanced Table: Added student avatars, gender display, and join date.
- Pagination: Implemented client-side pagination (10 items per page) to handle larger classes gracefully.
- Status Filtering: Added "Active/Inactive" filter with visual status badges (Emerald for active, muted for inactive).
- Data Access: Updated getClassStudents to fetch extended user profile data and support server-side status filtering.
Class Detail Dashboard (/teacher/classes/my/[id]/page.tsx):
- Dashboard Layout: Refactored into a responsive two-column layout (Main Content + Sidebar).
- Key Metrics: Added a 4-card stats grid at the top displaying critical insights:
  - Total Students (Active/Inactive breakdown)
  - Schedule Items (Weekly sessions)
  - Active Assignments (Overdue count)
  - Class Average (Based on graded submissions)
- Sidebar Widgets: Added "Class Schedule" and "Homework History" widgets for quick access to temporal data.
- Visual Polish: Integrated lucide-react icons throughout for better information scanning.

Dynamic Breadcrumbs (site-header.tsx):
- Replaced hardcoded "Dashboard > Overview" breadcrumbs with a dynamic system.
- Implemented a path-to-title lookup using NAV_CONFIG from src/modules/layout/config/navigation.ts.
- Added logic to filter out root role segments (admin/teacher/student/parent) for cleaner paths.
- Added fallback capitalization for segments not found in the config.
- Refactored SiteHeader to use usePathname for real-time route updates.

Type Safety (homework-grading-view.tsx):
- Fixed a TypeScript error where a boolean expression was returning boolean | undefined which is not a valid React node (implicit true check added).
- Resolved "Calling setState synchronously within an effect" React warning by initializing state lazily instead of using useEffect.
- Fixed implicit any type errors in map functions.
Linting:
- Cleaned up unused imports across multiple files (exam-actions.tsx, exam-assembly.tsx, textbook-reader.tsx, etc.).
- Fixed unescaped HTML entities in student-dashboard-header.tsx and others.
- Removed unused variables to clear ESLint warnings.
Refactoring:
- Updated TextbookCard to support hideActions prop for better reuse in student views.
- Added missing Progress component to src/shared/components/ui/progress.tsx.

Ran npm run typecheck: Passed (0 errors).
Ran npm run lint: Passed (0 errors, 28 warnings remaining for unused vars/components that may be needed later).
