feat(collections): implement rule testing/preview functionality (Limitation #1)
Add ability to test collection rules before saving:
- New API endpoint: POST /api/collections/test-rules
- Evaluates rules against all media items
- Returns matching books with reasons
- Supports all operators: equals, contains, greater_than, etc.
- Works with all fields: genre, author, series, etc.
Backend Implementation:
- TestRules() handler in collections.go
- evaluateRule() matches book properties against rule criteria
- compareValues() handles string/numeric comparisons
- Case-insensitive matching for contains operator
Frontend Integration:
- Updated testRule() function in collection_rules.templ
- Displays matching books with covers and authors
- Shows match reason (which rule criteria matched)
- Limits preview to 20 results with count indicator
Tests Added:
- TestCompareValues_Equals: Exact match validation
- TestCompareValues_Contains: Substring matching
- TestCompareValues_GreaterThan: Numeric comparison
- TestCompareValues_NotEquals: Negation
- TestEvaluateRule_Genre: Genre field matching
- TestEvaluateRule_Author: Author field matching
- TestEvaluateRule_CopyrightYear: Year field matching
API Request Format:
{
"rules": [{
"field": "genre",
"operator": "equals",
"value": "Science Fiction"
}]
}
API Response Format:
{
"matches": [{
"media_item_id": "uuid",
"title": "Book Title",
"author": "Author Name",
"cover_image_path": "/path/to/cover.jpg",
"match_reason": "Matched rule: genre equals Science Fiction"
}],
"total": 42
}
