+## Overview + +The predefined query filters system provides a flexible, reusable filtering mechanism for games across the Backlogia application. It enables users to filter their library, collections, and discovery pages using 18 predefined filters organized into 4 categories. + +**Key Feature:** Filters within the same category are combined with **OR** logic, while filters from different categories are combined with **AND** logic. This allows intuitive multi-selection within categories (e.g., "show played OR started games") while maintaining strict requirements across categories (e.g., "AND highly-rated"). + +## Architecture + +### Components + +#### 1. Filter Definitions (`web/utils/filters.py`) + +The core filter configuration is defined in `PREDEFINED_QUERIES`: + +```python +PREDEFINED_QUERIES = { + "filter_id": { + "label": "Display Name", + "description": "User-facing description", + "query": "SQL WHERE condition", + "category": "category_name" + } +} +``` + +**Categories:** +- `Gameplay`: Playtime-based status using system labels (5 filters: unplayed, just-tried, played, well-played, heavily-played). These filters use SQL subqueries against the `game_labels`/`labels` tables rather than direct column checks. See [System Labels documentation](system-labels-auto-tagging.md) for details. +- `Ratings`: Rating-based filters (7 filters: highly-rated, well-rated, critic-favorites, community-favorites, hidden-gems, below-average, unrated) +- `Dates`: Time-based filters (5 filters: recently-added, older-library, recent-releases, recently-updated, classics) +- `Content`: Content classification (2 filters: nsfw, safe) + +**Key Design Principles:** +- Each filter has a unique ID (kebab-case) +- SQL conditions are parameterized and injectable +- **Filters within the same category are combined with OR logic** +- **Filters from different categories are combined with AND logic** +- All filters respect store and genre selections + +#### 2. Query Parameter Parsing (`web/utils/filters.py`) + +**Function:** `parse_predefined_filters(query_string: str) -> list[str]` + +Parses URL query parameter `predefined` into a list of filter IDs. + +**Formats Supported:** +- Single: `?predefined=unplayed` +- Multiple (comma): `?predefined=unplayed,backlog` +- Multiple (repeated): `?predefined=unplayed&predefined=backlog` + +**Validation:** +- Unknown filter IDs are silently ignored +- Duplicate filter IDs are removed +- Empty/invalid values are filtered out + +#### 3. SQL Generation (`web/utils/filters.py`) + +**Function:** `build_query_filter_sql(query_ids: list[str], table_prefix: str = "") -> str` + +Converts filter IDs into SQL WHERE conditions with intelligent OR/AND logic. + +**Logic:** +1.

Other stores don't expose playtime data consistently. + +**Solution:** Use manual playtime tags for non-Steam games: +1. Open game detail page +2. Click the "Playtime: -" pill +3. Select appropriate tag (Never Launched, Just Tried, etc.) + +Manual tags persist and won't be overwritten by auto-tagging. + +--- + +### Q: Can I change the playtime boundaries (e.g., make "Played" 5-15h instead of 2-10h)? + +**A:** No, boundaries are hard-coded in `web/services/system_labels.py` in the `SYSTEM_LABELS` dictionary. Changing them requires: + +1. Editing the source code +2. Restarting the application +3. Running manual system tag update: `POST /api/labels/update-system-tags` + +However, you can **override** auto-tags with manual tags on a per-game basis: +- Open game detail page +- Click playtime tag pill +- Select different tag manually + +This gives you flexibility without modifying code. + +--- + +### Q: What happens if I delete a system label (e.g., "Well Played")? + +**A:** **Don't do this!** Deleting system labels will break auto-tagging and cause errors. + +**What breaks:** +- Auto-tagging will fail to assign labels for games in that playtime range +- Existing games with that label will lose the association (if CASCADE delete is configured) +- Filters relying on that label will return incorrect results + +**Recovery:** +1. Restart the application (runs `ensure_system_labels()` which recreates missing labels) +2. Run manual system tag update: `POST /api/labels/update-system-tags` + +**Protection:** System labels have `system = 1` flag. The UI should prevent deletion of system labels (user can only delete `system = 0` collections). + +--- + +### Q: Do manual tags get overwritten when I sync Steam? + +**A:** No! Manual tags (`auto = 0`) are **never** overwritten by auto-tagging. + +**How it works:** +- Auto-tagging only deletes and re-inserts labels where `auto = 1` +- Manual tags have `auto = 0` and are skipped during auto-tagging +- If you manually override a game's playtime tag, it won't change on next sync + +**Example:** +1. Steam game has 100h (auto-tags as "Heavily Played") +2. You manually change to "Just Tried" (sets `auto = 0`) +3. Next Steam sync runs → Your "Just Tried" tag persists + +To allow auto-tagging again, remove the manual tag: +- Click playtime pill → Select "Remove Tag" + +--- + +### Q: How do I bulk-unrate games (remove all ratings)? + +**A:** Use the bulk rating endpoint with `rating = 0`: + +1. **UI Method:** + - Enable multi-select mode (☑ button) + - Select games with ratings + - Bulk action: "Personal Rating" → "Remove Rating" (0 stars) + +2. **API Method:** + ```bash + curl -X POST http://localhost:5050/api/games/bulk/set-personal-rating \ + -H "Content-Type: application/json" \ + -d '{"game_ids": [123, 456, 789], "rating": 0}' + ``` + +Rating `0` sets `personal_rating` to `NULL` in the database. + +--- + +### Q: Can a game have multiple playtime tags? + +**A:** No, each game has **exactly one** playtime tag at a time (or none). + +**Why:** Playtime is a single numeric value, so only one tag applies. The system: +1. Deletes existing playtime tags (system labels with `system = 1`) +2. Inserts the single appropriate tag based on current playtime + +**Multiple labels:** Games can have multiple **collection** labels (user-created, `type = 'collection'`) but only one **system tag** (`type = 'system_tag'`). + +--- + +### Q: How do I see all games with a specific priority? + +**A:** Use the filter system: + +1. **UI Method:** + - Library page → Filter sidebar + - "My Rating" category → "Has Priority" + - (Note: Currently filters by existence, not specific priority level) + +2. **API Method:** + Query games with priority: + ```sql + SELECT * FROM games WHERE priority = 'high'; + ``` + +3. **Advanced:** Create a custom filter in `web/utils/filters.py` for specific priorities. + +--- + +### Q: What happens to collections when migrating from old system? + +**A:** The `migrate_collections_to_labels()` function automatically: + +1. Copies all `collections` → `labels` with `type = 'collection'` +2. Copies all `collection_games` → `game_labels` with `auto = 0` +3. Drops old `collections` and `collection_games` tables +4. Preserves all timestamps and associations + +**Migration is automatic** on first startup after upgrading. No manual action needed. + +**Data preserved:** +- Collection names and descriptions +- Game-collection associations +- Created/updated timestamps + +**New fields:** +- `type` = 'collection' (distinguishes from system tags) +- `icon`, `color` (NULL for migrated collections, can be set later) +- `system` = 0 (user-created) + +--- + +### Q: How fast is auto-tagging for large libraries? + +**A:** Performance depends on library size: + +- **Small (<100 games):** Instant (<0.1s) +- **Medium (100-1000 games):** 0.5-2 seconds +- **Large (1000-5000 games):** 2-10 seconds +- **Very Large (>5000 games):** 10-30 seconds + +**Optimization:** +- Batch processing (`update_all_auto_labels()`) is ~10x faster than individual +- Uses single transaction for atomic updates +- Indexes on `game_labels.game_id` and `label_id` accelerate queries + +**Measuring performance:** +Run the test suite: +```bash +pytest tests/test_edge_cases_labels.py::test_large_library_performance -v +``` + +--- + +### Q: Can I use labels/tags in custom filters? + +**A:** Yes! The filter system supports SQL subqueries against labels. + +**Example filter** (in `web/utils/filters.py`): +```python +{ + "name": "Has Priority", + "sql": "g.priority IS NOT NULL", + "category": "My Rating" +} +``` + +**Advanced example** (games with specific tag): +```python +{ + "name": "Well Played Games", + "sql": """EXISTS ( + SELECT 1 FROM game_labels gl + JOIN labels l ON l.id = gl.label_id + WHERE gl.game_id = g.id + AND l.name = 'Well Played' + AND l.system = 1 + )""", + "category": "Gameplay" +} +``` + +See [Filter System](filter-system.md) for more examples. + +--- + +### Q: What keyboard shortcuts are available in multi-select mode? + +**A:** The following shortcuts work in the library page when multi-select mode is enabled: + +| Shortcut | Action | +|----------|--------| +| Click checkbox | Toggle single game selection | +| Shift + Click | Select range from last clicked to current | +| Click action button | Apply action to all selected games | +| Esc | Cancel multi-select mode (UI convention, may not be implemented) | + +**Range selection example:** +1.
