Story 3.1 Implementation Summary

Overview

Implemented URL generation and site assignment for batch content generation, including full auto-creation capabilities and priority-based site assignment.

What Was Implemented

1. Database Schema Changes

• Modified: src/database/models.py

  • Made custom_hostname nullable in SiteDeployment model
  • Added unique constraint to pull_zone_bcdn_hostname
  • Updated __repr__ to handle both custom and bcdn hostnames

• Migration Script: scripts/migrate_story_3.1.sql

  • SQL script to update existing databases
  • Run this on your dev database before testing

2. Repository Layer Updates

• Modified: src/database/interfaces.py

  • Changed custom_hostname to optional parameter in create() signature
  • Added get_by_bcdn_hostname() method signature
  • Updated exists() to check both hostname types

• Modified: src/database/repositories.py

  • Made custom_hostname parameter optional with default None
  • Implemented get_by_bcdn_hostname() method
  • Updated exists() to query both custom and bcdn hostnames

3. Template Service Update

• Modified: src/templating/service.py
  • Line 92: Changed to hostname = site_deployment.custom_hostname or site_deployment.pull_zone_bcdn_hostname
  • Now handles sites with only bcdn hostnames

4. CLI Updates

• Modified: src/cli/commands.py
  • Updated sync-sites command to import sites without custom domains
  • Removed filter that skipped bcdn-only sites
  • Now imports all bunny.net sites (with or without custom domains)

5. Site Provisioning Module (NEW)

• Created: src/generation/site_provisioning.py
  • generate_random_suffix(): Creates random 4-char suffixes
  • slugify_keyword(): Converts keywords to URL-safe slugs
  • create_bunnynet_site(): Creates Storage Zone + Pull Zone via API
  • provision_keyword_sites(): Pre-creates sites for specific keywords
  • create_generic_sites(): Creates generic sites on-demand

6. URL Generator Module (NEW)

• Created: src/generation/url_generator.py
  • generate_slug(): Converts article titles to URL-safe slugs
  • generate_urls_for_batch(): Generates complete URLs for all articles in batch
  • Handles custom domains and bcdn hostnames
  • Returns full URL mappings with metadata

7. Job Config Extensions

• Modified: src/generation/job_config.py
  • Added tier1_preferred_sites: Optional[List[str]] field
  • Added auto_create_sites: bool field (default: False)
  • Added create_sites_for_keywords: Optional[List[Dict]] field
  • Full validation for all new fields

8. Site Assignment Module (NEW)

• Created: src/generation/site_assignment.py
  • assign_sites_to_batch(): Main assignment function with full priority system
  • _get_keyword_sites(): Helper to match sites by keyword
  • Priority system:
    • Tier1: preferred sites → keyword sites → random
    • Tier2+: keyword sites → random
  • Auto-creates sites when pool is insufficient (if enabled)
  • Prevents duplicate assignments within same batch

9. Comprehensive Tests

• Created: tests/unit/test_url_generator.py - URL generation tests
• Created: tests/unit/test_site_provisioning.py - Site creation tests
• Created: tests/unit/test_site_assignment.py - Assignment logic tests
• Created: tests/unit/test_job_config_extensions.py - Config parsing tests
• Created: tests/integration/test_story_3_1_integration.py - Full workflow tests

10. Example Job Config

• Created: jobs/example_story_3.1_full_features.json
  • Demonstrates all new features
  • Ready-to-use template

How to Use

Step 1: Migrate Your Database

Run the migration script on your development database:

-- From scripts/migrate_story_3.1.sql
ALTER TABLE site_deployments MODIFY COLUMN custom_hostname VARCHAR(255) NULL;
ALTER TABLE site_deployments ADD CONSTRAINT uq_pull_zone_bcdn_hostname UNIQUE (pull_zone_bcdn_hostname);

Step 2: Sync Existing Bunny.net Sites

Import your 400+ existing bunny.net buckets:

uv run python main.py sync-sites --admin-user your_admin --dry-run

Review the output, then run without --dry-run to import.

Step 3: Create a Job Config

Use the new fields in your job configuration:

{
  "jobs": [{
    "project_id": 1,
    "tiers": {
      "tier1": {"count": 10}
    },
    "tier1_preferred_sites": ["www.premium.com"],
    "auto_create_sites": true,
    "create_sites_for_keywords": [
      {"keyword": "engine repair", "count": 3}
    ]
  }]
}

Step 4: Use in Your Workflow

In your content generation workflow:

from src.generation.site_assignment import assign_sites_to_batch
from src.generation.url_generator import generate_urls_for_batch

# After content generation, assign sites
assign_sites_to_batch(
    content_records=generated_articles,
    job=job_config,
    site_repo=site_repository,
    bunny_client=bunny_client,
    project_keyword=project.main_keyword
)

# Generate URLs
urls = generate_urls_for_batch(
    content_records=generated_articles,
    site_repo=site_repository
)

# urls is a list of:
# [{
#   "content_id": 1,
#   "title": "How to Fix Your Engine",
#   "url": "https://www.example.com/how-to-fix-your-engine.html",
#   "tier": "tier1",
#   "slug": "how-to-fix-your-engine",
#   "hostname": "www.example.com"
# }, ...]

Site Assignment Priority Logic

For Tier1 Articles:

1. Preferred Sites (from tier1_preferred_sites) - if specified
2. Keyword Sites (matching article keyword in site name)
3. Random from available pool

For Tier2+ Articles:

1. Keyword Sites (matching article keyword in site name)
2. Random from available pool

Auto-Creation:

If auto_create_sites: true and pool is insufficient:

• Creates minimum number of generic sites needed
• Uses project main keyword in site names
• Creates via bunny.net API (Storage Zone + Pull Zone)

URL Structure

With Custom Domain:

https://www.example.com/how-to-fix-your-engine.html

With Bunny.net CDN Only:

https://mysite123.b-cdn.net/how-to-fix-your-engine.html

Slug Generation Rules

• Lowercase
• Replace spaces with hyphens
• Remove special characters
• Max 100 characters
• Fallback: article-{content_id} if empty

Testing

Run the tests:

# Unit tests
uv run pytest tests/unit/test_url_generator.py
uv run pytest tests/unit/test_site_provisioning.py
uv run pytest tests/unit/test_site_assignment.py
uv run pytest tests/unit/test_job_config_extensions.py

# Integration tests
uv run pytest tests/integration/test_story_3_1_integration.py

# All Story 3.1 tests
uv run pytest tests/ -k "story_3_1 or url_generator or site_provisioning or site_assignment or job_config_extensions"

Key Features

Simple Over Complex

• No fuzzy keyword matching (as requested)
• Straightforward priority system
• Clear error messages
• Minimal dependencies

Full Auto-Creation

• Pre-create sites for specific keywords
• Auto-create generic sites when needed
• All sites use bunny.net API

Full Priority System

• Tier1 preferred sites
• Keyword-based matching
• Random assignment fallback

Flexible Hostnames

• Supports custom domains
• Supports bcdn-only sites
• Automatically chooses correct hostname

Production Deployment

When moving to production:

1. The model changes will automatically apply (SQLAlchemy will create tables correctly)
2. No additional migration scripts needed
3. Just ensure your production .env has BUNNY_ACCOUNT_API_KEY set
4. Run sync-sites to import existing bunny.net infrastructure
