Magendoo Omnibus Price Tracker

A Magento 2 module that records product price history and computes the lowest price in a configurable window, satisfying the requirements of the EU Omnibus Directive 2019/2161 (Article 6a).

The directive requires that any price reduction must show the lowest price from the preceding 30 days — measured not from today, but from the moment the reduction began. This module implements that anchored-window algorithm correctly.

Requirements

No RabbitMQ required: all queue topics are pinned to Magento's MySQL-backed db queue connection (queue_message table), so the async pipeline works on any standard Magento installation. Consumers run through Magento cron (consumers_runner) or a process manager — see Async processing.

Installation

The module is distributed via its GitHub repository (it is not published on Packagist).

Via Composer (recommended)

Add the repository to your project's composer.json:

"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/magendooro/module-omnibus"
    }
]

Install and enable:

composer require magendoo/module-omnibus:^2.0
bin/magento module:enable Magendoo_Omnibus
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush

Manual installation

Copy the module directory to app/code/Magendoo/Omnibus/, then run the same setup:upgrade / setup:di:compile / cache:flush sequence.

Quick Start

After installation, navigate to:

Stores → Configuration → Magendoo Extensions → Omnibus Price Tracker

1. Set Enable Price History to Yes
2. Set Period in Days to 30 (minimum required by the Directive; increase for a wider safety margin)
3. Set Display Mode to Discounted Products Only (recommended for compliance)
4. Set Display Omnibus Prices On to Product Pages Only or Product and Category Pages — the default is None, which records history but renders nothing on the storefront
5. Click Save Config → the module queues a full catalog recompute on the magendoo.omnibus.recompute queue (make sure consumers are running)
6. Seed an initial baseline so products have history to compute from:

bin/magento omnibus:history:restore --force

The omnibus_price product attribute is then populated and the label renders on the configured surfaces.

Configuration Reference

general/* settings are scoped per website. label/* settings are scoped per store view so the label can be translated for each language (store view is Magento's locale boundary); an untranslated store view inherits the website/default value. cleanup/* and cron/* are global.

All recorded_at timestamps are stored in UTC.

CLI Commands

All three commands refuse to run (exit non-zero) while magendoo_omnibus/general/enabled is 0.

# Recompute omnibus_price for all products on all websites
bin/magento omnibus:prices:recompute

# Recompute for a single product (all websites)
bin/magento omnibus:prices:recompute --product-id=42

# Recompute for a single product on a specific website
bin/magento omnibus:prices:recompute --product-id=42 --website-id=2

# Delete history older than the configured retention period, or a given date.
# The newest pre-cutoff record per product/website/group is always preserved.
bin/magento omnibus:history:clean
bin/magento omnibus:history:clean --before=2025-01-01
bin/magento omnibus:history:clean --before="2025-01-01 12:00:00"

# Wipe and rebuild history (fresh snapshot + full recompute).
# Prints the actual inserted row count, per-product coverage, and how many
# products ended up with a stored omnibus_price value.
# Requires confirmation unless --force is passed.
bin/magento omnibus:history:restore
bin/magento omnibus:history:restore --force
bin/magento omnibus:history:restore --force --website-id=1

Admin Interface

Marketing → Omnibus → Price Change History

The price history grid displays every recorded price change across your catalog. Columns: ID, SKU, Website, Customer Group, Price Type, Price (excl. tax), Price (incl. tax), Source, Recorded At, Actions.

Filterable columns include SKU (text), Website, Customer Group, Price Type, Source, and Recorded At (date range).

• Row action: Delete — POST with confirmation dialog.
• Mass action: Delete selected — POST.
• Toolbar button: Restore History — wipes the history table and rebuilds it from a full catalog snapshot (POST with confirmation; only visible to admins holding the manage ACL resource). Refuses to run while the module is disabled globally or for any website: the capture/recompute services no-op when disabled, so the wipe would never be re-seeded.

All destructive endpoints accept POST only; GET requests are rejected.

ACL resources

Product attributes

Async processing

Bulk capture and recompute work runs through two message queue topics on the MySQL (db) queue connection:

• magendoo.omnibus.capture — price capture for single products (catalog rule changes, imports, drift sync)
• magendoo.omnibus.recompute — omnibus_price recompute batches (config changes)

Magento's cron consumers_runner starts the consumers automatically. To run them under a process manager instead:

bin/magento queue:consumers:start magendoo.omnibus.capture
bin/magento queue:consumers:start magendoo.omnibus.recompute

A single product save in admin/API is captured synchronously (so the product page is correct immediately); everything else is queued.

How It Works

See docs/how-it-works.md for a full explanation of the anchored-window algorithm (including the carry-in rule), the price resolution chain, and the complete event capture pipeline.

Architecture

See docs/architecture.md for the module structure, database schema, DI wiring, queue topology, and cron schedule.

Testing

See docs/testing.md for the PHPUnit suite inventory and manual verification checklist.

Roadmap

Reserved for future versions (constants exist in Api/Data/PriceHistoryInterface, but no code writes them yet):

• Per-customer-group price tracking (tier / group price types)
• REST API write sources (api, api_override source labels)
• Cart price rule (checkout promotion) disclosure — the v1.x salesrule.is_omnibus column was removed in v2.0.0 and may return as a separate feature

Changelog

v2.0.0 — 2026-07-18

Major refactor. Breaking changes — review before upgrading from v1.x:

Removed

• Config field general/display_child_products (never implemented), constant OmnibusConfigInterface::XML_PATH_DISPLAY_CHILD_PRODUCTS, method Config::isDisplayChildProducts()
• Methods Config::getSyncCronSchedule() / Config::getCleanupCronSchedule() (schedules are read by etc/crontab.xml directly)
• DB column salesrule.is_omnibus — dropped on setup:upgrade; any data in that column is lost — and the sales_rule_form.xml checkbox that wrote it
• Redundant index MGDOO_OMNIBUS_HIST_PROD_WEB_TIME_IDX (the unique key covers the same prefix)
• The magendoo.omnibus.cleanup queue topic and its consumer (cleanup deletes directly, no queue round-trip)
• Admin grid filter options that were never written: sources API / API Override, price types Tier / Group (interface constants remain reserved)

Fixed / changed

• Window query now applies the carry-in rule: the price in force before the window opened is part of the minimum, so a product with a long-stable price gets a correct reference price
• History retention (omnibus:history:clean and the cleanup cron) always keeps the newest pre-cutoff row per product/website/customer group — the future carry-in
• Catalog rule changes, imports, config changes, and drift sync now publish to the message queue instead of doing bulk work inline; product save stays synchronous
• Drift-sync cron pre-filters with a single SQL query per website and queues only genuinely drifted products
• Config-change recompute is gated on the changed paths (enabled, period_in_days, display_mode)
• PLP label implemented (pricing render plugin, pdp_and_plp mode); previously advertised but missing
• Special price date handling: a special_from_date of today is active from the start of the day
• All timestamps generated in UTC via the framework date library
• Admin: ACL split into view/delete/manage/configuration; destructive endpoints POST-only; Restore button hidden without the manage resource
• CLI commands exit with an error when the module is disabled; restore prints real inserted/coverage counts
• Data patches are re-runnable (skip attribute creation when the attribute exists)

Notes

• Product deletion also deletes that product's price history (ON DELETE CASCADE on the history table). If you need audit history to survive product deletion, export before deleting products.
• composer.json version 2.0.0; module description updated to match actual behavior.

v1.0.0 — 2026-04-16

Initial release:

• Price capture from admin save, catalog rules, Magento Import, config change, nightly cron
• Anchored 30-day window algorithm
• Async queue processing (MySQL-backed)
• Admin price history grid with filters, mass-delete, and restore
• CLI commands, omnibus_price and omnibus_hide EAV product attributes
• PHPUnit unit test suite
