name: newsletter-events-update-event description: Manually refresh specific event pages to update event data

<essential_principles>

Purpose

Re-scrape specific event page URLs to update event data in the database. Use this when event details have changed (date, time, venue, etc.) or to verify event information.

When to Use

• Event details have changed and need updating
• You want to verify/refresh event data from the source
• A page was scraped but events weren't extracted correctly

URL Handling

• URLs are normalized before lookup (trailing slashes, tracking params stripped)
• The normalized URL must match what's in the scraped_pages table
• If URL not found in database, it will be scraped as new

Multi-Event Pages

Some pages contain multiple events (e.g., weekly schedules). When updating:

• ALL events with matching source_url are updated
• New events on the page are created
• Events no longer on the page are NOT deleted (they may have passed) </essential_principles>

Examples:

• https://hvmag.com/events/jazz-night-jan-20
• https://example.com/event/123 https://example.com/event/456

Provide the URL(s):

Extract all URLs from user input.

Copyimport re

url_pattern = r'https?://[^\s<>"\']+'
urls = re.findall(url_pattern, user_input)

if not urls:
    print("ERROR: No valid URLs found in input")
    # STOP HERE

Step 2: Normalize and Lookup

Copyfrom scripts.url_utils import normalize_url
from schemas.sqlite_storage import SqliteStorage
from pathlib import Path

db_path = Path.home() / ".config" / "local-media-tools" / "data" / "events.db"
storage = SqliteStorage(db_path)

# Normalize URLs
url_map = {normalize_url(url): url for url in urls}

# Check which URLs exist in scraped_pages
for normalized_url, original_url in url_map.items():
    # Find the source_name for this URL (query scraped_pages)
    page_record = None
    with storage._connection() as conn:
        row = conn.execute(
            "SELECT source_name, url, scraped_at FROM scraped_pages WHERE url = ?",
            (normalized_url,),
        ).fetchone()
        if row:
            page_record = dict(row)

    if page_record:
        print(f"ℹ Found: {original_url}")
        print(f"  Source: {page_record['source_name']}")
        print(f"  Last scraped: {page_record['scraped_at']}")
    else:
        print(f"⚠ Not found in database: {original_url}")
        print(f"  Will be scraped as new URL")

Step 3: Re-scrape Pages

Copyfrom scripts.scrape_firecrawl import FirecrawlClient, FirecrawlError

client = FirecrawlClient()
scraped_pages = []

for normalized_url, original_url in url_map.items():
    try:
        page = client.scrape_url(original_url)
        scraped_pages.append({
            "normalized_url": normalized_url,
            "original_url": original_url,
            "markdown": page.get("markdown", ""),
            "title": page.get("title", ""),
        })
        print(f"✓ Scraped: {original_url}")
    except FirecrawlError as e:
        print(f"✗ Failed to scrape {original_url}: {e}")

Step 4: Extract Events (Claude)

For each scraped page, analyze the markdown and extract events.

For each page:

1. Read the markdown content
2. Extract event details (title, date, time, venue, description, price, etc.)
3. Create Event objects with source_url set to the original URL

Copyfrom schemas.event import Event, Venue, EventSource

event = Event(
    title=extracted_title,
    venue=Venue(name=venue_name, address=venue_address),
    event_date=parsed_date,
    start_time=parsed_time,
    source=EventSource.WEB_AGGREGATOR,
    source_url=page["original_url"],
    description=description,
    price=price,
    ticket_url=ticket_url,
    confidence=0.9,  # Higher confidence for manual refresh
    needs_review=False,  # User explicitly requested this update
)

Step 5: Update Database

For each page, update or create events, then update the scraped_pages record.

Copyfrom schemas.event import EventCollection

for page in scraped_pages:
    events_from_page = events_by_url.get(page["original_url"], [])

    # 1. Save/update events
    if events_from_page:
        collection = EventCollection(events=events_from_page)
        result = storage.save(collection)
        print(f"  → {len(events_from_page)} events: {result.saved} new, {result.updated} updated")
    else:
        print(f"  → No events extracted from page")

    # 2. Update scraped_pages record
    # Determine source_name (from existing record or ask user)
    if page_record:
        source_name = page_record["source_name"]
    else:
        # For new URLs, try to infer source from config or use domain
        from urllib.parse import urlparse
        source_name = urlparse(page["original_url"]).netloc

    storage.save_scraped_page(
        source_name=source_name,
        url=page["normalized_url"],
        events_count=len(events_from_page),
    )

print(f"\n✓ Update complete")

Step 6: Report Results

Display summary of what was updated:

<success_criteria>

• All URLs parsed from input
• URLs normalized for consistent lookup
• Pages re-scraped via Firecrawl
• Events extracted from markdown
• Events saved BEFORE URL marked as scraped
• scraped_pages records updated with new timestamp
• Summary shown to user </success_criteria>
