CLI Helpers

wp altek-sync bootstrap --batch=500
wp altek-sync run-worker

Admin Panel (visual guide)

The settings screen shows:

• Total WordPress products.
• Total Altek products (Postgres).

Initial Bootstrap (SKU comparison)

Compares WooCommerce SKUs against Postgres and enqueues only missing ones:

wp altek-sync bootstrap --batch=500

Run the worker manually (optional):

wp altek-sync run-worker

Queue Table in WordPress

{wp_prefix}altek_sync_queue

Statuses:

• pending
• processing
• retry
• done
• failed

v1 Mapping Woo -> inv_items

• item: trim(product.sku). If numeric and shorter than 9 digits, it is left-padded with zeros to 9 digits.
• codigobarras: product.sku
• nombre: product.name
• nombreweb: product.name
• existencia: product.stock_quantity (when stock is managed)
• costoestandar: product.regular_price
• costopromedio: product.regular_price
• id_altek: product.id (WordPress ID)
• imagen: featured image URL
• bloqueado: FALSE on create/update
• costoultimacompra (optional): meta _altek_last_cost if present
• idcategoria (optional): first Woo category
• observaciones (optional): short_description
• alto (optional): product.height when numeric
• ancho (optional): product.width when numeric

Database Recommendations

Before production:

• Create uniqueness on normalized SKU (upper(trim(item))).
• Define an official product deletion policy (soft/hard).
• Use a least-privilege PostgreSQL user.
• Confirm SSL (sslmode=require) when applicable.
