From aa9e8dc427439ca3e117cf897b635473db4384a1 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 30 Nov 2025 16:19:06 +0000 Subject: [PATCH 1/3] fix: Handle punctuation differences in site domain matching MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Critical fix for E.Leclerc and similar sites where DB domain differs from config key by punctuation (. vs -). **Problem:** - DB contains: "e.leclerc" (with dot) - Config key: "e-leclerc.com" (with dash) - Previous matching failed: no match found **Solution:** Enhanced matching with 5-level strategy: 1. **Exact match** - as before 2. **Normalized punctuation match** (NEW) - Remove all `-` and `.` from both sides - Compare: "e.leclerc" → "eleclerc", "e-leclerc.com" → "eleclecrcom" - Use contains logic: "eleclerc" in "eleclecrcom" → ✅ MATCH 3. **Contains match** - with original punctuation 4. **Prefix removal** - now handles both "e-" and "e." (plus "la-", "la.") 5. **Fuzzy core match** - last resort for edge cases **Impact:** - ✅ E.Leclerc now matches correctly - ✅ La Foir'Fouille handles variations - ✅ Any site with punctuation differences works - ✅ Backward compatible with existing matches **Debug logging:** All strategies log which method matched, making issues easy to diagnose. --- app/services/improved_search_service.py | 60 ++++++++++++++++++++++--- 1 file changed, 55 insertions(+), 5 deletions(-) diff --git a/app/services/improved_search_service.py b/app/services/improved_search_service.py index a22c155..9de7ac6 100644 --- a/app/services/improved_search_service.py +++ b/app/services/improved_search_service.py @@ -625,7 +625,7 @@ async def search_products( for site in active_sites: matched = False - # Normalize domain for comparison (remove www., e-, etc.) + # Normalize domain for comparison (remove www., lowercase, etc.) normalized_domain = site.domain.lower().replace("www.", "").strip() for key in SITE_CONFIGS.keys(): @@ -639,16 +639,48 @@ async def search_products( logger.debug(f"✓ Matched {site.domain} → {key} (exact)") break - # 2.

Try configured selector first (as before) 2. If no results, try 11 common e-commerce patterns: - Product URL patterns: /produit, /product, /p/, /item - Class patterns: article a, .product a, .product-card a - Generic patterns: [class*='product'] a 3. Accept first selector that finds >= 3 links 4. Log which selector worked for debugging **Selector Priority:** - Most specific first (URL patterns) - Medium specificity (semantic classes) - Generic last resort (any product-related class) **Benefits:** - ✅ Works on more sites without manual config updates - ✅ Resilient to site HTML changes - ✅ Clear logging shows which selector worked - ✅ Still uses configured selector when available - ✅ Requires >= 3 matches to avoid false positives **Expected Impact:** Sites like Auchan should now find products even if configured selector is outdated, without needing a specialized parser. --- app/services/parsers/generic_parser.py | 35 +++++++++++++++++++++++++- 1 file changed, 34 insertions(+), 1 deletion(-) diff --git a/app/services/parsers/generic_parser.py b/app/services/parsers/generic_parser.py index 65c1018..ca093d3 100644 --- a/app/services/parsers/generic_parser.py +++ b/app/services/parsers/generic_parser.py @@ -50,6 +50,8 @@ class GenericParser(BaseParser): Uses: - product_selector: CSS selector for product links - product_image_selector: CSS selector for images (optional) + + If configured selector fails, tries common fallback selectors.

Fnac - No Images Displayed** Problem: FnacParser only searched for images in parent container, missing images nested directly in the link element. Solution: Two-priority search - PRIORITY 1: Search in link element first (picture, img) - PRIORITY 2: Search in parent container - Added warning log when no image found - Ensures parent is always defined before use **2. L'Incroyable - 0 Products (Shopify sites)** Problem: GenericParser fallbacks didn't include Shopify patterns. L'Incroyable uses Shopify structure with /products/ URLs. Solution: Added Shopify-specific fallbacks - a[href*='/products/'] (Shopify product URLs) - a.product-card__link (Shopify class) - a[href*='/collections/'] (Shopify collections) - li[class*='product'] a (list-based layouts) **Fallback Order (now 17 selectors):** 1. Product URL patterns (Shopify, generic) 2. Semantic classes (article, .product-card) 3. Shopify-specific selectors 4. Generic structure patterns 5. Last resort wildcards **Expected Impact:** - ✅ Fnac images should now display - ✅ L'Incroyable should find products (Shopify) - ✅ Better coverage of Shopify-based stores --- app/services/parsers/fnac_parser.py | 31 +++++++++++++++++++++----- app/services/parsers/generic_parser.py | 5 +++++ 2 files changed, 31 insertions(+), 5 deletions(-) diff --git a/app/services/parsers/fnac_parser.py b/app/services/parsers/fnac_parser.py index faa42a1..ef2ae87 100644 --- a/app/services/parsers/fnac_parser.py +++ b/app/services/parsers/fnac_parser.py @@ -80,11 +80,30 @@ class FnacParser(BaseParser): if not self.filter_by_query(title, query): continue - # Extract image + # Extract image - try in link first, then parent image_url = None parent = link.find_parent(["article", "li", "div"]) - if parent: - # Try picture > source first + + # PRIORITY 1: Try in the link itself + picture = link.find("picture") + if picture: + source = picture.find("source") + if source and source.get("srcset"): + image_url = source.get("srcset").split(",")[0].split()[0] + if not image_url: + img = picture.find("img") + if img: + image_url = self._get_image_src(img) + + # Try img directly in link + if not image_url: + img = link.find("img") + if img: + image_url = self._get_image_src(img) + + # PRIORITY 2: Try in parent container + if not image_url and parent: + # Try picture > source picture = parent.find("picture") if picture: source = picture.find("source") @@ -101,8 +120,10 @@ class FnacParser(BaseParser): if img: image_url = self._get_image_src(img) - if image_url: - image_url = self.make_absolute_url(image_url) + if image_url: + image_url = self.make_absolute_url(image_url) + else: + self.logger.warning(f"No image found for Fnac product: {title[:40]}...") # Extract price price = None diff --git a/app/services/parsers/generic_parser.py b/app/services/parsers/generic_parser.py index ca093d3..d000ef3 100644 --- a/app/services/parsers/generic_parser.py +++ b/app/services/parsers/generic_parser.py @@ -73,6 +73,7 @@ class GenericParser(BaseParser): fallback_selectors = [ # Product-specific URLs "a[href*='/produit']", + "a[href*='/products/']", # Shopify "a[href*='/product']", "a[href*='/p/']", "a[href*='/item']", @@ -82,9 +83,13 @@ class GenericParser(BaseParser): ".product-card a[href]", ".product-item a[href]", "[class*='product'] a[href]", + # Shopify specific + "a.product-card__link", + "a[href*='/collections/']", # Generic structure "article[class*='product'] a", "div[class*='product'] a", + "li[class*='product'] a", # Very generic (last resort) "a[class*='product']", ]
