 # DEVLOG - ComfyUI-Workflow-Studio

+## 2026-04-28: v0.3.2 生成UIタブ — Checkpoint Batch・Seed UIレイアウト修正
+
+### 概要
+
+- 生成UIタブの右パネルに **Checkpoint Batch** 機能を追加
+- Seed行のレイアウトを2段構成に変更（seed値とモード選択が見切れる問題を解消）
+
+### 変更内容
+
+#### `templates/index.html` — UI要素追加・修正
+
+**Checkpoint Batch パネル追加:**
+- 右パネル（Seed行の下・結果表示の上）に `wfm-ckpt-batch-panel` を追加
+- チェックボックス ON/OFF でバッチ設定欄を展開/折りたたみ
+- Include Folders テキスト入力 — カンマ区切りでサブフォルダ名を指定。空欄でcheckpointフォルダ内の全モデルを対象
+- Exclude Folders テキスト入力 — カンマ区切りで除外するサブフォルダ名を指定
+- 対象モデル数プレビュー表示 (`wfm-ckpt-batch-info`)
+- バッチ進捗エリア — 現在のモデル名、インデックス/総数、アンバー色プログレスバー (`wfm-ckpt-batch-bar`)
+
+**Seed レイアウト修正:**
+- 横並び1行（`flex-direction: row`）→ 縦2行（`flex-direction: column`）に変更
+- 1行目: `Seed:` ラベル + 数値入力（`flex:1` で横幅いっぱい）
+- 2行目: モード選択セレクト（`width:100%`）
+
+**ヘルプタブ:**
+- GenerateUI タブ説明に gen-11（Checkpoint Batch の説明）を追加
+- gen-8（Seed control）に2段レイアウト化の補足を追加
+
+#### `static/js/generate-tab.js` — バッチロジック追加・生成処理リファクタリング
+
+**新規追加:**
+- `_ckptBatch` — `{ aborted: false }` バッチ中断フラグ
+- `_parseFolderList(str)` — カンマ区切り文字列をトリム・小文字化して配列に変換
+- `_getModelFolder(modelPath)` — パスの最初の `/` より前を抽出してフォルダ名を取得。`\\` を `/` に正規化、ルート直下は `""` を返す
+- `_filterCheckpoints(checkpoints, includeStr, excludeStr)` — include/exclude フィルタを適用したチェックポイントリストを返す。大文字小文字を区別しない
+- `_updateBatchInfo()` — チェックポイントリストのフィルタ済み件数を `wfm-ckpt-batch-info` に即時反映
+- `initCheckpointBatch()` — チェックボックス・include/exclude 入力のイベントリスナーを登録
+- `_coreGenerate(silent)` — 1回の生成コア処理（`silent=true` のとき完了トーストを省略）。エラー時はスローする
+- `_runBatchGenerate()` — チェックポイントリストをループし `_coreGenerate` を順番に呼び出す。各反復でワークフロー内の全checkpointノードの `ckpt_name` を書き換える。エラーは件数カウントして継続。完了後に結果サマリをトースト表示
+
+**変更:**
+- `handleGenerate()` — バッチが有効な場合は `_runBatchGenerate()` を、無効の場合は `_coreGenerate(false)` を呼び出すよう分岐。ボタン管理（disabled / Stop 表示）を共通 try/finally で処理
+- interrupt ボタンのハンドラ — `_ckptBatch.aborted = true` を設定してから `comfyUI.interrupt()` を呼び出し、単発生成とバッチの両方を停止できるように
+- Refresh Models ボタンのハンドラ — モデルリスト再取得後に `_updateBatchInfo()` を呼び出してバッチ件数を更新
+- `initGenerateTab()` — 末尾で `initCheckpointBatch()` を呼び出し。初期接続成功時に `_updateBatchInfo()` を呼び出し

+- `folderCreate`, `folderDelete`, `imagesDelete`, `imagesMove`
+
+**state追加:**
+- `folderTree` — ツリー全体データを保持（移動先フォルダ一覧の生成に使用）
+
+**フォルダツリー展開状態の保持:**
+- `_getExpandedPaths()` — 再構築前に展開済みフォルダのパスを `Set` で収集
+- `_restoreTreeState(expandedPaths, selectedPath)` — 再構築後に展開状態・選択ハイライトを復元。階層の浅い順に展開することで子ノードのDOM存在を保証
+- `renderTreeNode` — 各アイテムに `data-path` 属性を付与（復元の識別子）
+- `loadFolderTree` — 初回ロード判定（`isFirstLoad`）を追加。2回目以降は `_restoreTreeState` を呼び出して展開状態を維持
+
+**フォルダ操作:**
+- `createFolder()` — `prompt()` でフォルダ名入力後、API呼び出し・ツリー再読み込み
+- `deleteFolder()` — 確認ダイアログ後、再帰削除・currentFolder リセット・ツリー再読み込み
+- フォルダラベルクリック時に Delete Folder ボタンの `disabled` 状態を更新（ルート選択時は削除不可）
+
+**ファイル削除・移動:**
+- `performDeleteImages(paths)` — 削除後に `state.images` / `state.selectedImages` を即時更新。詳細パネルの選択中画像が削除された場合はパネルをリセット
+- `performMoveImages(paths, dest)` — 移動後に同様に state を即時更新
+- `flattenFolderTree(node)` — ツリーデータをフラットリストに変換（移動先選択に使用）
+- `openMoveModal(paths)` — 移動先フォルダ選択モーダルを動的生成。現在フォルダを除く全フォルダをドロップダウン表示
+- 詳細パネルの Move To... / Delete ボタンを画像選択時に有効化
+
+#### `templates/index.html` — UI要素追加
+
+- フォルダツリーヘッダーに「+ New」「Del」ボタン（`wfm-gallery-tree-actions`）
+- 詳細パネル Info タブに「Move To...」「Delete」ボタン（`wfm-gallery-file-actions`）
+- 一括バーに「Move To...」「Delete」ボタン
+- ヘルプ項目を10項目から11項目に更新
+
+#### `static/css/gallery-tab.css` — スタイル追加
+
+- `.wfm-gallery-tree-header` — `justify-content: space-between` でタイトルとボタンを両端配置
+- `.wfm-gallery-tree-actions` — フォルダ操作ボタンのフレックスコンテナ
+- `.wfm-gallery-file-actions` — 詳細パネルのファイル操作ボタン
+- `.wfm-gallery-move-modal` / `.wfm-gallery-move-modal-title` / `.wfm-gallery-move-dest-sel` / `.wfm-gallery-move-modal-footer` — 移動先選択モーダル
+
+#### `static/js/generate-tab.js` — ワークフロー自動保存
+
+- `_outputDir` モジュール変数 — outputパスをキャッシュ
+- `_fetchOutputDir()` — `/api/wfm/settings/output-dir` からoutputパスを取得
+- `saveGeneratedImagesMeta(images, workflow)` — 生成完了後、各画像のフルパスを組み立てて `/wfm/gallery/image/meta` にワークフローを保存。`type !== "output"` の一時ファイルはスキップ
+- `initGenerateTab` — 初期化時に `_fetchOutputDir()` を実行。`wfm-output-dir-changed` イベントで設定変更時にパスを同期
+- `handleGenerate` — 生成成功後に `saveGeneratedImagesMeta` を非同期呼び出し
+
+### 技術的な判断
+
+- **ツリー展開状態の復元**: `innerHTML = ""` による完全再構築を維持しつつ、展開パスを `Set` で保存して復元する方式を採用。差分DOMパッチより実装が単純で、フォルダ追加・削除後のツリー構造変化にも対応できる
+- **PNG `prompt` キーの参照**: ComfyUIのSaveImageノードはデフォルトでPNGに `prompt` キー（API形式）のみを埋め込む。`workflow` キー（UI形式）が埋め込まれるのは特定の操作時のみ。`prompt` を参照することで既存の全ComfyUI生成画像に対応
+- **フォールバック優先順位**: PNG埋め込み（`workflow` > `prompt`）> `gallery_metadata.json` の順とし、ComfyUI本体が埋め込んだデータを最優先に
+

+- `renderGroupFilter()` 改善 — ドロップダウンオプションを `[Checkpoint] GroupName` / `[LoRA] GroupName` 形式で全タイプ分表示。値は `type::groupName` としてエンコード
+- グループフィルター `change` ハンドラ更新 — 選択したグループが現在と異なるタイプの場合、モデルタイプタブを自動切り替えしてモデルを再ロード
+- `saveModelGroups()` — 保存時に `state.allModelGroups[type]` も更新
+- `loadModelsForCurrentType()` — ロード時に `state.allModelGroups[type]` を同期
+- `loadMetadataAndModels()` — 初回ロード時に `fetchAllModelGroups()` で全タイプのグループを一括取得
+
+#### `web/comfyui/node_sets_menu.js` — サイドパネルのModel Groupsビュー修正
+
+- `renderModelGroups()` を新タイプ別形式 `{ type: { groupName: [...] } }` に対応

+
+**state追加:**
+
+- `disabledModels: {}` — タイプ別の無効モデルSet
+- `statusFilter: "all"` — "all" / "enabled" / "disabled"

+- ヘルプ: `helpModels11`（複数選択・一括削除の説明）、`helpModels3` 更新（ステータスフィルター追記）
+
+### 技術的な判断
+
+- **拡張子リネーム方式**: ComfyUIはスキャン時に認識拡張子のみ列挙するため、`.disabled`サフィックスを付けるだけでモデルを隠せる。ファイル移動や専用DBを使わず最もシンプルな実装
+- **DOM直接更新（選択モード）**: 選択トグルのたびに`renderModelGrid()`を呼ぶと大量再レンダリングが起きる。`querySelectorAll("[data-model-name]")`で対象要素を絞り`classList.toggle()`のみ実行
+- **stemバグの根本原因**: `path.stem`は最後のサフィックスのみ除去する。`model.safetensors.disabled`の`stem`は`model.safetensors`になるため、`model.safetensors.png`を探してしまう。`.disabled`を先に除去してから`Path.stem`を計算する必要がある
+
+---
+
+## 2026-04-14: v0.2.8 データ保存先変更・エクスポート/インポート機能追加
+
+### 概要
+
+- プラグインデータの保存先を `custom_nodes/ComfyUI-Workflow-Studio/data/` から `ComfyUI/user/default/Workflow-Studio/` に変更
+- `user/default/` が存在しない環境（Portable版・Dockerなど）では従来の `data/` にフォールバック
+- 設定タブに「データ管理」セクションを追加（エクスポート/インポート機能）
+
+### 変更内容
+
+#### `py/config.py` — DATA_DIR 保存先変更
+
+**`DATA_DIR` の解決ロジックを変更:**
+
+- 変更前: `DATA_DIR = PLUGIN_DIR / "data"` （固定）
+- 変更後: `user/default/` が存在すれば `DATA_DIR = _COMFYUI_USER_DEFAULT / "Workflow-Studio"`、存在しなければ `PLUGIN_DIR / "data"` にフォールバック
+- `_COMFYUI_ROOT` の定義位置を `DATA_DIR` の前に移動（`_COMFYUI_WORKFLOWS` と共用）
+
+#### `py/routes/settings_routes.py` — エクスポート/インポートAPI追加
+
+**新エンドポイント:**
+
+- `GET /api/wfm/settings/export` — `settings.json`, `metadata.json`, `node_metadata.json`, `node_sets.json`, `prompts.json`, `model_metadata.json`, `gallery_metadata.json` の7ファイルを1つのJSONバンドルとして返す（`Content-Disposition: attachment` でDL）

+
+**追加キー（英語・日本語・中国語）:**
+
+- `dataManagement`, `dataManagementHint`, `exportData`, `importData`
+- `exportSuccess`, `exportError`, `importSuccess`, `importError`
+
+#### `templates/index.html` / `static/js/app.js` / `static/js/i18n.js` — ヘルプタブ更新
+
+- `wfm-help-settings-8` をデータ管理の説明に変更
+- `wfm-help-settings-9`（アコーディオン説明）を追加（HTML・app.jsマッピング・i18n 3言語）
+
+### 移行手順（既存ユーザー向け）
+
+1. 設定タブ →「データ管理」→「エクスポート」で `wfm-data-export.json` を保存
+2. ComfyUIを再起動（新パスで空の状態で起動）
+3. 設定タブ →「データ管理」→「インポート」でエクスポートしたファイルを選択
+4. ComfyUIを再起動して反映
+
+または手動で `custom_nodes/ComfyUI-Workflow-Studio/data/` の内容を `ComfyUI/user/default/Workflow-Studio/` にコピーしてから再起動。

 ## Changelog

+### v0.3.2
+- **Checkpoint Batch** — new panel in the GenerateUI right column (below Seed, above results); enable via checkbox to auto-generate once per checkpoint model; filter included/excluded subfolders by comma-separated names (empty = all checkpoints); real-time preview of matched model count; amber progress bar shows current model name and index; Stop button aborts the loop after the current generation completes; failed models are counted and reported in the summary toast
+- **Seed layout fix** — seed value input and mode selector (Random / Fixed / Increment / Decrement) now stacked vertically so neither is clipped in narrow panels
+
+### v0.3.1
+- **Folder operations** — create subfolders and delete folders (with all contents) directly from the folder tree header buttons
+- **File operations** — move or delete individual images from the detail panel; bulk move and bulk delete from the multi-select bar
+- **Tree state preserved** — folder expansion state is maintained after create/delete/move/refresh operations
+- **Workflow viewer improved** — Metadata tab now reads both `prompt` (API format, the default for most ComfyUI-generated images) and `workflow` (UI format) keys from PNG metadata, covering virtually all ComfyUI output
+- **Workflow auto-save** — after each generation in the Generate UI tab, the current workflow is automatically saved to gallery metadata for the generated images; shown in the Metadata tab even if PNG embedding is absent
+
+### v0.3.0
+- **Cross-type group filter** — the group filter dropdown in the Models tab now shows groups from all model types simultaneously, each prefixed with a type label (`[Checkpoint]`, `[LoRA]`, etc.); selecting a group automatically switches to the corresponding model type
+- **Sidebar group display fixed** — the ComfyUI sidebar "Model Groups" view now correctly renders per-type groups (introduced in v0.2.9) with a type label on each group header; fixes a crash where `.filter is not a function` was thrown on the new nested group structure
+
+### v0.2.9
+- **Model Enable/Disable** — hide models from ComfyUI by renaming the file extension to `.disabled`; toggle per model (⏸ button on each card/row), per group (Enable All / Disable All buttons in the Group panel), or filter the grid by status (All / Enabled only / Disabled only). Changes take effect after ComfyUI refresh.
+- **Per-type model groups** — groups are now scoped to each model type; checkpoint groups only appear in the Checkpoint tab, LoRA groups only in the LoRA tab, etc. Existing flat groups are automatically migrated.
+- **Multi-select mode** — click the Select button in the toolbar to enter selection mode; check individual models across Thumbnail / Card / Table views
+- **Bulk group operations** — with models selected, add or remove them from any group in one click, or create a new group and add them simultaneously
+- **Bulk file delete** — permanently delete selected model files along with all associated preview images and sidecar files (`.json`, `.civitai.info`, `.info`); requires confirmation before deleting
+- **Bug fix** — models in subdirectories could not be disabled due to a path-doubling error; fixed by computing the rename target from `path.name` instead of `model_name`
+- **Bug fix** — Hypernetwork tab showed `C`, `O`, `M`, `B` as fake model items; caused by the new ComfyUI API format returning `"COMBO"` as the first element; fixed in `comfyui-client.js`
+
+### v0.2.8
+- **Data storage moved** — plugin data (settings, metadata, prompts, etc.) is now stored in `ComfyUI/user/default/Workflow-Studio/` instead of `custom_nodes/ComfyUI-Workflow-Studio/data/`; falls back to the old `data/` directory if `user/default/` does not exist
+- **Data Management section** — new Settings tab section to export all plugin data to a single JSON file and import it back; useful for migration, backup, and reinstallation
+
 ### v0.2.7
 - **Gallery tab** — new image browser for ComfyUI output folder; Thumbnail/Table views, multi-select with Bulk Bar, server-side group/tag/favorite filtering, group management (rename support), performance-optimized with  + mtime folder cache
 - **Group UI unified** — Workflow, Nodes, and Gallery group panels rebuilt to match the Models tab 4-section pattern (Current Groups / Add to Group / Create New Group / Manage Groups); Rename support added to Workflow and Nodes tabs
