Changelog - November 23, 2025

Summary

Major improvements to shop frontend functionality, landing pages, and cart system. Fixed critical issues preventing products from being added to cart, refactored templates for proper styling, and established comprehensive navigation architecture.

Landing Page System

Features Added

• ✅ Vendor landing pages at root URLs (/, /vendors/{code}/)
• ✅ Four template options: default, minimal, modern, full
• ✅ CMS-powered content management via ContentPage model
• ✅ Auto-redirect to /shop/ when no landing page exists
• ✅ Two-tier navigation: landing page (/) + shop (/shop/)

Templates Created

1. app/templates/vendor/landing-default.html - Clean professional layout
2. app/templates/vendor/landing-minimal.html - Ultra-simple centered design
3. app/templates/vendor/landing-modern.html - Full-screen with animations
4. app/templates/vendor/landing-full.html - Split-screen with maximum features

Supporting Files

• scripts/create_landing_page.py - Interactive landing page creator
• docs/features/vendor-landing-pages.md - Complete usage guide
• docs/frontend/shop/navigation-flow.md - Navigation architecture
• TEST_LANDING_PAGES.md - Testing guide

Database Changes

• Migration f68d8da5315a: Added template field to content_pages table
• Supports values: default, minimal, modern, full

Shop Template Refactoring

Problem Fixed

Pages displayed without styling due to:

• Standalone HTML structure (not extending base template)
• Hardcoded CSS references to non-existent files
• Missing header, footer, and navigation

Templates Refactored

1. Product Detail Page (shop/product.html)

Before: 770 lines of standalone HTML with custom CSS After: 403 lines extending base template

Changes:

• Extends shop/base.html for consistent styling
• Removed hardcoded CSS files
• Added breadcrumbs with landing page navigation
• Integrated with shopLayoutData() for cart functionality
• Uses Tailwind classes + theme CSS variables
• Proper Alpine.js component inheritance

2. Shopping Cart Page (shop/cart.html)

Before: 489 lines standalone HTML After: 319 lines extending base template

Changes:

• Extends shop/base.html
• Modern responsive grid layout
• Integrated toast notifications
• Proper session management
• Breadcrumbs and navigation
• Removed 437 lines of redundant custom CSS

Benefits

• ✅ Consistent styling across all pages
• ✅ Automatic header/footer/navigation
• ✅ Theme variables applied correctly
• ✅ Mobile responsive out of the box
• ✅ Dark mode support
• ✅ Reduced code duplication

Cart Functionality Fixes

Critical Issue: Products Can't Be Added to Cart

Root Cause:

• Products had available_inventory: 0
• inventory table was empty
• available_inventory is calculated from inventory_entries
• canAddToCart check failed

Solution:

• Created scripts/create_inventory.py
• Populates inventory table with 100 units per product
• Now products can be added to cart successfully

Session Management Issue

Root Cause:

• sessionId was undefined in cart/product components
• Parent shopLayoutData() init not being called
• Alpine.js inheritance wasn't working correctly

Solution:

• Store reference to baseData before spreading
• Explicitly call baseData.init.call(this) in child components
• Session ID now properly initialized across all pages

Code Pattern:

const baseData = shopLayoutData();
return {
    ...baseData,
    async init() {
        if (baseData.init) {
            baseData.init.call(this);  // Initialize session
        }
        await this.loadData();
    }
};

Routing and Navigation Fixes

Duplicate /shop/ Prefix

Problem: Routes like /vendors/wizamart/shop/shop/products/4

Root Cause:

# Router mounted with prefix
app.include_router(router, prefix="/shop")

# Routes incorrectly repeated prefix
@router.get("/shop/products/{id}")  # ❌ Wrong

Fix:

@router.get("/products/{id}")  # ✅ Correct

All routes in shop_pages.py fixed.

Missing /shop/ in Template Links

Problem: Links went to /vendors/wizamart/products instead of /shop/products

Fix: Updated all templates:

• shop/base.html - Header, footer, navigation
• shop/products.html - Product links
• shop/product.html - Breadcrumbs, related products
• shop/cart.html - Continue shopping, checkout
• shop/errors/404.html - All fallback links
• shop/account/*.html - Login, register links

Navigation Architecture

Established two-tier system:

• Landing Page (/) - Marketing, branding, vendor story
• Shop (/shop/) - E-commerce, products, cart, checkout

Navigation Pattern:

• Logo → /shop/ (stay in shop for convenience)
• Breadcrumb "Home" → / (return to landing page)
• Header "Home" → / (return to landing page)

Placeholder Image System

Problem

• Missing images showed broken icon
• Placeholder was .jpg file containing SVG content
• Browsers won't render SVG from non-SVG file

Solution

• Created proper /static/shop/img/placeholder.svg
• Added @error handlers to all image tags
• Automatic fallback when images fail to load

<img
    :src="product.image_link || '/static/shop/img/placeholder.svg'"
    @error="$el.src = '/static/shop/img/placeholder.svg'"
    alt="Product"
>

Updated templates:

• shop/product.html - Main image, thumbnails, related products
• shop/products.html - Product grid
• shop/cart.html - Cart item images
