* Create new model for storing Part pricing data Currently this model does not "do" anything but will be used for caching pre-calculated pricing information * Define function for accessing pricing information for a specific part * Adds admin site support for new PartPricing model * Specify role for PartPricing model * Allow blank values for PartPricing model fields * Add some TODO entries * Update migration files to sync with latest master * Expose API endpoint for viewing part pricing information * Update migration file * Improvements: - Updated model with new fields - Code for calculating BOM price - Code for calculating internal price - Code for calculating supplier price - Updated unit testing * Fix (and test) for API serializer * Including min/max pricing data in part serializer * Bump API version * Add pricing overview information in part table - Adds helper function for formatting currency data - No longer pre-render "price strings" on the server * Overhaul of BOM API - Pricing data no longer calculated "on the fly" - Remove expensive annotation operations - Display cached price range information in BOM table * Filter BOM items by "has pricing" * Part API endpoint can be filtered by price range * Updpated API version notes * Improvements for price caching calculations - Handle null price values - Handle case where conversion rates are missing - Allow manual update via API * Button to manually refresh pricing * Improve rendering of price-break table * Update supplier part pricing table * Updated js functions * Adds background task to update assembly pricing whenever a part price cache is changed * Updates for task offloading * HTML tweaks * Implement calculation of historical purchase cost - take supplier part pack size into account - improve unit tests * Improvements for pricing tab rendering * Refactor of pricing page - Move javascript functions out into separate files - Change price-break tables to use bar graphs - Display part pricing history table and chart - Remove server-side rendering for price history data - Fix rendering of supplier pricing table - Adds extra filtering options to the SupplierPriceBreak API endpoint * Refactor BOM pricing chart / table - Display as bar chart with min/max pricing - Display simplified BOM table * Update page anchors * Improvements for BOM pricing table display * Refactoring sales data tables - Add extra data and filter options to sales order API endpoints - Display sales order history table and chart * Add extra fields to PartPricing model: - sale_price_min - sale_price_max - sale_history_min - sale_history_max * Calculate and cache sale price data * Update part pricing when PurchaseOrder is completed * Update part pricing when sales order is completed * Signals for updating part pricing cache - Whenever an internal price break is created / edited / deleted - Whenever a sale price break is created / edited / deleted * Also trigger part pricing update when BomItem is created / edited / deleted * Update part pricing whenever a supplier price break is updated * Remove has_complete_bom_pricing method * Export min/max pricing data in BOM file * Fix pricing data in BOM export - Calculate total line cost - Use more than two digits * Add pricing information to part export Also some improvements to part exporting * Allow download of part category table * Allow export of stock location data to file * Improved exporting of StockItem data * Add cached variant pricing data - New fields in part pricing model - Display variant pricing overview in "pricing" tab * Remove outdated "PART_SHOW_PRICE_HISTORY" setting * Adds scheduled background task to periodically update part pricing * Internal prices can optionally override other pricing * Update js file checks * Update price breaks to use 6 decimal places * Fix for InvenTreeMoneySerializer class - Allow 6 decimal places through the API * Update for supplier price break table * javascript linting fix * Further js fixes * Unit test updates * Improve rendering of currency in templates - Do not artificially limit to 2 decimal places * Unit test fixes * Add pricing information to part "details" tab * Tweak for money formatting * Enable sort-by-price in BOM table * More unit test tweaks * Update BOM exporting * Fixes for background worker process - To determine if worker is running, look for *any* successful task, not just heartbeat - Heartbeat rate increased to 5 minute intervals - Small adjustments to django_q settings Ref: https://github.com/inventree/InvenTree/issues/3921 (cherry picked from commit cb26003b92536f67fba640d84aa2a6596d18b4e0) * Force background processing of heartbeat task when server is started - Removes the ~5 minute window in which the server "thinks" that the worker is not actually running * Adjust strategy for preventing recursion - Rather than looking for duplicate parts, simply increment a counter - Add a "scheduled_for_update" flag to prevent multiple updates being scheduled - Consolidate migration files * Adds helper function for rendering a range of prices * Include variant cost in calculations * Fixes for "has_pricing" API filters * Ensure part pricing status flags are reset when the server restarts * Bug fix for BOM API filter * Include BOM quantity in BOM pricing chart * Small tweaks to pricing tab * Prevent caching when looking up settings in background worker - Caching across mnultiple processes causes issues - Need to move to something like redis to solve this - Ref: https://github.com/inventree/InvenTree/issues/3921 * Fixes for /part/pricing/ detail API endpoint * Update pricing tab - Consistent naming * Unit test fixes * Prevent pricing updates when loading test fixtures * Fix for Part.pricing * Updates for "check_missing_pricing" * Change to pie chart for BOM pricing * Unit test fix * Updates - Sort BOM pie chart correctly - Simplify PartPricing.is_valid - Pass "limit" through to check_missing_pricing - Improved logic for update scheduling * Add option for changing how many decimals to use when displaying pricing data * remove old unused setting * Consolidate settings tabs for pricing and currencies * Fix CI after changing settings page * Fix rendering for "Supplier Pricing" - Take unit pricing / pack size into account * Extra filtering / ordering options for the SupplierPriceBreak API endpoint * Fix for purchase price history graph - Use unit pricing (take pack size into account) * JS fixes

🌟 About the Project
InvenTree is an open-source Inventory Management System which provides powerful low-level stock control and part tracking. The core of the InvenTree system is a Python/Django database backend which provides an admin interface (web-based) and a REST API for interaction with external interfaces and applications.
InvenTree is designed to be lightweight and easy to use for SME or hobbyist applications, where many existing stock management solutions are bloated and cumbersome to use. Updating stock is a single-action process and does not require a complex system of work orders or stock transactions.
Powerful business logic works in the background to ensure that stock tracking history is maintained, and users have ready access to stock level information.
