# Implementation Plan - Catalog Scraper Fix
|
||||
|
||||
## Problem
|
||||
|
||||
The catalog scraper (`cataloguemate_scraper.py`) fails to retrieve catalogs because the `browserless` service is likely being blocked or failing to connect (based on logs). However, the target site (`cataloguemate.fr`) is accessible via simple HTTP requests.
|
||||
|
||||
## Proposed Changes
|
||||
|
||||
### 1. Modify `app/services/cataloguemate_scraper.py`
|
||||
|
||||
We will implement a fallback mechanism in `scrape_catalog_list`:
|
||||
|
||||
- **Primary Method**: Continue using `browserless_service.get_page_content`.
|
||||
- **Fallback Method**: If `browserless` returns no content or fails, use `httpx.AsyncClient` to fetch the HTML directly.
|
||||
- **Parsing**: Use `BeautifulSoup` to parse the HTML from either source.
|
||||
|
||||
#### [MODIFY] [cataloguemate_scraper.py](file:///c:/Users/Michael/VSCODE/Priceflow-1/app/services/cataloguemate_scraper.py)
|
||||
|
||||
- Import `httpx` and `random` (for user-agents).
|
||||
- In `scrape_catalog_list`, add a `try/except` block or check for empty content.
|
||||
- If content is missing, call a new helper or inline `httpx` request with standard headers.
|
||||
|
||||
## Verification Plan
|
||||
|
||||
### Automated Verification
|
||||
|
||||
Since we cannot run the full app locally (docker/dependencies issues), we will verify by code review and logic.
|
||||
|
||||
### Manual Verification (User)
|
||||
|
||||
1. User triggers the catalog update (via Admin or Scheduler).
|
||||
2. User checks logs to see if "Fallback to HTTP" message appears.
|
||||
3. User verifies that catalogs (e.g. B&M, Gifi) appear in the dashboard.

## 🚀 Current Focus
|
||||
|
||||
- [x] Analysing current hybrid (Text + Image) extraction logic
|
||||
- [x] Proposing "Vision First" strategy to owner
|
||||
- [ ] **Implementation Phase**:
|
||||
- [ ] Update `ai_schema.py` STRICT Vision Definition.
|
||||
- [ ] Refine Prompt with "IMAGE IS TRUTH" directive.
|
||||
- [ ] **Verification Phase**:
|
||||
- [ ] Verify prompt generation.
|
||||
- [ ] Debug Catalog Scraper
|
||||
|
||||
## 📋 Master Plan
|
||||
|
||||
- [x] Analyze `verify_extraction_logic.py`, `ai_service.py`, `ai_schema.py`, `tracking_scraper_service.py`.
|
||||
- [x] Proposal Phase: Vision Priority accepted.
|
||||
- [ ] Implementation Phase:
|
||||
- [x] Update `ai_schema.py`.
|
||||
- [x] Fix `scheduler_service.py` (Disable conflicting Text AI).
|
||||
- [x] Verification Phase: Verified with `verify_vision_priority.py`.
|
||||
- [ ] **Catalog Issue**:
|
||||
- [x] Reproduce failure (Confirmed Browserless issue via analysis).
|
||||
- [x] Fix `cataloguemate_scraper.py` with HTTP fallback.

||||

||||
## 📝 Progress Log
|
||||
|
||||
- **2025-12-22**: Initialized task. Confirmed current system is *already* sending images, but likely confusing the AI with conflicting text data.
|
||||
- **2025-12-22**: User selected **Option 2 (Vision Priority)**. Proceeding to rewrite AI System Prompt.
|
||||
- **2025-12-22**: **FIX**: Detected that `scheduler_service.py` was prioritizing a text-only extractor (0.99€ found in text) before checking the image. Disabled the text-only extractor to force Vision AI usage.
|
||||
- **2025-12-22**: Vision Priority implemented and verified.
|
||||
- **2025-12-22**: User reported Catalog issue. Logic identified as `cataloguemate.fr`.
|
||||
- **2025-12-22**: Initial debug script failed (missing dependencies). Creating v2 using internal services.
