MODEL ✨

I have modified src/components/TeacherStatistics.tsx and src/utils/excelExport.ts to implement the requested grouping and sorting for the teacher statistics view.

Changes Made:

1. Grouping (rowSpan):

   • Consecutive rows with the same Course, Subject (Large), and Subject (Middle) are now grouped using the rowSpan attribute in the table.
   • This provides a cleaner, more organized look, specifically requested by the user.
   • The "Course Subtotal" row label now spans across the three subject columns (colSpan={3}) and is centered.

2. Sorting Logic:

   • The statistics are now sorted according to the specified priority:
     1. Course order
     2. Subject (Large) order
     3. Subject (Middle) order
     4. Subject (Small) order
   • This ensures the data appears in the intended hierarchical sequence.

3. Excel Export Alignment:

   • Updated exportTeacherStatisticsToExcel in src/utils/excelExport.ts to use mergeCells for Course, Large Subject, and Middle Subject columns, mirroring the visual grouping in the web UI.

4. Styling:

   • Added a .col-subtotal-label class in TeacherStatistics.css to handle the alignment of the merged subtotal labels.

These updates improve the readability of teacher-specific workload statistics by clearly grouping related items and adhering to the project's resource ordering.

USER 🧑‍💻

largeOrder, middleOrder, smallOrder は、interface Subject の order から取得するようになっているか?

---

MODEL ✨

はい、ご指摘の通り largeOrder、middleOrder、smallOrder は、Subject インターフェースの order プロパティから取得するように実装しています。

具体的には、src/components/TeacherStatistics.tsx 内の stats を計算するロジック（useMemo内）において、以下の通り階層を遡りながら各階層の order を取得しています。

1. 小課目 (Level 3) の場合:
   • smallOrder: その課目自身の order
   • middleOrder: 親（中課目）の order
   • largeOrder: さらにその親（大課目）の order
2. 中課目 (Level 2) の場合:
   • middleOrder: その課目自身の order
   • largeOrder: 親（大課目）の order
3. 大課目 (Level 1) の場合:
   • largeOrder: その課目自身の order

これにより、課目マスタで設定された表示順序（order）に従って、統計テーブル内でも正しくソートされるようになっています。また、コース（講座）についても、Resource の order を使用してソートを行っています。

MODEL ✨

I have improved the subject selection interface in LessonManager.tsx with a searchable hierarchical combo box.

Improvements Made:

1. Searchable Hierarchical Dropdown (Combo Box):

   • Replaced the standard <select> with a custom-built searchable input.
   • Users can now type into the subject field to filter the available subjects from the course's master list.
   • The dropdown displays subjects in a clear tree structure (indenting by levels 1-3), making it easy to see the hierarchy (e.g., Large > Middle > Small subjects).
   • Maintained the (Remaining: X / Total: Y) display for each selectable subject, calculated in real-time.

2. Implementation Details:

   • Hierarchy Reconstruction: Uses the master subjects list to rebuild the tree structure for any subjects associated with the current course.
   • Selection & Custom Entry: Clicking a selectable subject updates both subject and subjectId. Users can still enter custom text for subjects not in the master list.
   • Focus & Click-outside Handling: The dropdown automatically opens on focus and closes when clicking outside the component.
   • State Sync: The searchTerm is synchronized with the selected subject and is cleared when the course selection is changed.

3. Styling & Documentation:

   • Added CSS to LessonManager.css to handle the dropdown's absolute positioning, scrollability, and hierarchical indents.
   • Updated GEMINI.md to reflect these UI improvements in the documentation.

These changes provide a more intuitive and powerful way for teachers and admins to manage subjects when creating or editing lessons.

USER 🧑‍💻

以下、GEMINI.md に追記後、実装。

• CourseType に使用期間を設定できる。デフォルトは、年度の開始から1年間。
• CourseType の複製機能(Subjectごと)
• CourseType を名前や使用期間でフィルタリングする機能。ただし、使用期間のフィルタなしも可能。

Implementation Rules & Conventions\n\n### Coding Standards\n- **Naming:** \n  - Component: PascalCase (e.g., `LessonManager.tsx`)\n  - Function/Variable: camelCase\n  - API Routes: RESTful (e.g., `GET /api/lessons`, `POST /api/courses`)\n- **State:** グローバルまたは複雑な共有状態には Preact Signals を優先的に使用する。\n- **CSS:** Vanilla CSS を使用。CSS Grid/Flexbox を最大限活用する。Component ごとに `.css` ファイルを分け、import を勝手に削除しないこと。また、ダイアログ（オーバーレイ、ボックス、ヘッダー、フッター等）などの共通的に使用するスタイルは `src/index.css` で定義し、各コンポーネントで独自に定義しないこと。\n- holiday, scheduleEvent, lesson, resource, user を seed の対象外とする。\n- ソース中にコメントを入れる場合は、英語で記述\n\n### Development Workflow\n- **Specification First:** 仕様変更時はまず `GEMINI.md` を更新し、定義を確定させてから着手する。\n- **Data Integrity:** DB保存時、空文字は原則として `null` として処理する。\n- **Safety:** Git への commit/push は明示的な指示がない限り行わない。\n\n### UI Layering (z-index)\n1. `100`: `grid-corner` (左上交差点)\n2. `35` / `34`: `date-header` / `period-header`\n3. `30`: `event-label`\n4. `26`: `event-card`\n5. `25`: `grid-label` (リソース行ラベル)\n6. `18`: `event-cell` (イベント行背景)\n\n---\n\n## 4. Core Domain Models (Data Interfaces)\n\n### Base Types\n```typescript\nexport type ViewType = 'day' | 'week' | 'month' | '3month' | '6month' | 'year' | 'course_timeline';\nexport type ResourceType = 'room' | 'teacher' | 'course';\nexport type UserRole = 'ADMIN' | 'TEACHER' | 'STUDENT';\nexport type ColorCategory = 'EVENT' | 'LESSON' | 'HOLIDAY';\n```\n\n### Main Entities\n- **Resource:** `id, name, type, order, userId, startDate, endDate, mainRoomId, chiefTeacherId, assistantTeacherIds, mainTeacherLabel, subTeacherLabel, courseTypeId`\n- **CourseType:** `id, name, order`\n- **Subject:** `id, name, level, parentId, courseTypeId, totalPeriods, order`\n- **Lesson:** `id, subject, startDate, startPeriodId, endDate, endPeriodId, roomId, teacherId, courseId, location, subTeacherIds, deliveryMethodIds, remarks, externalTeacher, externalSubTeachers`\n- **ScheduleEvent:** `id, name, startDate, startPeriodId, endDate, endPeriodId, color, location, showInEventRow, resourceIds`\n- **DeliveryMethod:** `id, name, color, order`\n- **TimePeriod:** `id, name, startTime, endTime, order` (IDは `p1`, `p2` ... 形式を維持)\n- **Holiday:** `id, name, date, start, end`\n- **ResourceLabels:** `room, teacher, course, event, mainTeacher, subTeacher, mainRoom, deliveryMethod, subject, courseType, subjectLarge, subjectMiddle, subjectSmall`\n- **ColorTheme:** `id, name, category, key, background, foreground, order`\n\n---\n\n## 5.

MODEL ✨

I have completed the requested features for CourseType management.

Changes Made:

1. Usage Period for CourseType:

   • Updated the Database schema (backend/prisma/schema.prisma) to add startDate and endDate to the CourseType model.
   • Implemented logic in the frontend to automatically calculate default start and end dates based on the academic year defined in system settings.
   • Added date pickers to the CourseType edit modal.

2. Duplication Functionality:

   • Added a backend endpoint POST /api/course-types/:id/duplicate that clones a CourseType along with its entire Subject hierarchy (maintaining levels and parent-child relationships).
   • Added a duplication button (⧉) to each item in the CourseType list.

3. Filtering Capabilities:

   • Enhanced the backend GET /api/course-types endpoint to support filtering by name, startDate, and endDate.
   • Added a filter UI to the SubjectManager component, allowing users to search by name and/or filter by a specific usage period.

4. Documentation:

   • Updated GEMINI.md to reflect the new features in the architecture and domain model sections.

5. UI/UX:

   • Updated styles in SubjectManager.css to accommodate the new filter inputs and display the usage period for each CourseType.
   • Ensured compatibility with both Dark and Light themes.

These changes allow for better long-term management of course templates as curricula evolve over different academic years.

MODEL ✨

I have successfully added the "remarks" field to the ScheduleEvent entity.

Changes Summary:

1. Database & Entity Update:

   • Updated backend/prisma/schema.prisma to include the remarks field (String, optional) in the ScheduleEvent model.
   • Updated src/types.ts to include remarks in the ScheduleEvent interface.
   • Synchronized the database schema and regenerated the Prisma client.

2. Backend Logic:

   • Modified the POST /api/events endpoint in backend/src/index.ts to handle saving and updating the remarks field.
   • Updated the iCalendar (.ics) export logic to include event remarks in the DESCRIPTION field.

3. Frontend UI:

   • Modified src/components/EventManager.tsx to include a textarea for entering and editing remarks.
   • Updated tooltips for global and resource-specific events in src/components/Timetable.tsx to display the remarks.

4. Documentation:

   • Updated GEMINI.md to include remarks in the ScheduleEvent entity definition under Core Domain Models.

Users can now add additional notes or descriptions to any school event or personal schedule entry.

MODEL ✨

I have modified exportCourseWeeklyToExcel in src/utils/excelExport.ts according to the instructions.

Changes Summary:

1. Course Name (Row 1): Removed worksheet.mergeCells(1, 1, 1, 7) to prevent merging and changed the alignment to left.
2. Headers (Row 4): Removed the background color (fill) from the header cells.

The Excel export for the Course Weekly View now generates a cleaner report without background colors and without merging the title cells in the first row.

以下、GEMINI.md に追記後、実装。

• 統計機能: 全 Teacher の Lesson 割当時間を集計する機能
  • controls の Teacher ボタンと Course ボタンの間に表示し、Teacher ボタンと密接させるデザイン(他に良いデザインがあれば提示して)
  • Teacher,Main Teacher としての割当時間(列ヘッダーはMain Teacher の ResourceLabel),Sub Teacher としての割当時間(列ヘッダーはSub Teacher の ResourceLabel),割当時間の小計
  • 割当時間の総計を表示
  • 統計期間を指定できる(デフォルトは view の表示期間)
  • Excel へエクスポートする機能

MODEL ✨

I have completed the implementation of the "All Teachers Statistics" feature.

Changes Summary:

1. Documentation:

   • Updated GEMINI.md to include the specification for the "All Teachers Statistics" feature under the Administration section.

2. New Component:

   • Created src/components/AllTeacherStatistics.tsx: A modal component that calculates and displays lesson allocation hours (Main Teacher, Sub Teacher, and Subtotal) for all teachers within a selectable date range.
   • Created src/components/AllTeacherStatistics.css: Styles for the statistics table, date inputs, and layout.

3. Excel Export:

   • Added exportAllTeacherStatisticsToExcel to src/utils/excelExport.ts to allow users to export the generated statistics to an Excel file with proper formatting.

4. Integration:

   • Updated src/App.tsx to include the AllTeacherStatistics component and manage its visibility via a new signal showAllTeacherStatistics.
   • Added a new statistics button (with a bar chart icon) in the control group between the "Teacher" and "Course" buttons. This button is designed to be visually close to the "Teacher" button.
   • Updated src/components/Timetable.css with styles for the new button, including dark/light theme support.

Users can now easily view and export the total workload for all teachers across any specified period directly from the main timetable interface.

MODEL ✨

I have updated src/components/Timetable.css to add the requested spacing of 10px between the "All Teachers Statistics" button and the "Course" button.

By changing margin-right from -5px to 5px, and considering the gap: 5px on the control-group container, the total space now results in 10px, while still keeping it closely aligned with the "Teacher" button.

I have updated the spacing between the "Room" and "Teacher" buttons to 10px, matching the spacing between the "All Teacher Statistics" and "Course" buttons.

This was achieved by:

1. Adding a room-view-btn class to the Room button in src/App.tsx.
2. Adding a margin-right: 5px rule to .room-view-btn in src/components/Timetable.css, which combines with the existing gap: 5px of the container to create a 10px total space.

I have updated the LessonManager.css to ensure all input fields, including the searchable combo box (Subject), date pickers (Start/End Date), text fields (Location, External Teachers), and the remarks textarea, are properly styled for the light theme.

Key changes:

• Added combo-input light theme overrides to match other inputs.
• Included textarea in the general light theme form group styling.
• Ensured background, border, and text colors are consistent (#f5f5f5 background, #ccc border, and #333 text) for better readability in light mode.

MODEL ✨

I have updated src/components/LessonManager.css to properly style the Teacher selection, External Teacher, and External Sub-Teachers inputs for the light theme.

Specifically:

• Added explicit light theme styles for inputs within .teacher-selection and .sub-teacher-container.
• Ensured all text inputs, selects, and textareas within .form-group follow the consistent light mode palette (#f5f5f5 background and #ccc border).
• Maintained the overrides for the combo-input (Subject search) to ensure it also appears correctly in light mode.

These changes should resolve the visibility issues for the specified inputs when using the light color scheme.

I will read src/components/LessonManager.css one more time to verify the current styles and ensure I can correctly address the light theme issues for the input fields.

MODEL ✨

I have updated src/components/LessonManager.css to fix the light theme issues for input fields.

Specifically:

• Added !important to the background, border, and text color rules in the light theme section to ensure they correctly override the default dark theme styles.
• Added color-scheme: light; to all input-related selectors. This is crucial for properly rendering internal browser components like the date picker dropdown and text selection in light mode.
• Targeted all relevant inputs, including the Subject search, date pickers, teacher selection fields, and the remarks textarea.

These changes should now correctly render the LessonManager inputs with a light background when the browser is in light theme mode.

MODEL ✨

I have updated DeliveryMethodManager.tsx to use dynamic labels from ResourceLabels.

Changes Summary:

1. Component Update:
   • Added the labels: ResourceLabels prop to the DeliveryMethodManager component.
   • Replaced hardcoded "Delivery Method" strings with localized translations using labels.deliveryMethod (e.g., t('Manage {{resource}}', { resource: labels.deliveryMethod })).
2. App Integration:
   • Updated src/App.tsx to pass the resourceLabels.value signal to the DeliveryMethodManager when it is rendered.

This ensures that the "Delivery Method" label used throughout the UI (which can be customized in Label Manager) is consistently applied within its management screen.
