This pull request introduces several enhancements and new features to the warehouse management system, including improvements to data population scripts, database schema updates, API functionality, and development environment configuration. Below is a summary of the most important changes grouped by theme.

Database and Schema Updates:

• Added a product_SKU field to the Product model, ensuring each product has a unique SKU identifier. Corresponding migration 0002_product_product_sku.py was created. ([[1]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-e3126b89490ff95fab29bef220d891c5e08d044da990375f9f106e42769ef374R1-R18), [[2]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-0cc46d5940330f7605259aec8e81d57aa0d4ccde56d5dea8638e58ccbc9ffe03R10))
• Introduced a capacity field to the Warehouse model to track the maximum storage capacity. Corresponding migration 0002_warehouse_capacity.py was created. ([[1]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-83711e32fd1d050ba9ed1c889bf7463e38584657e8df37494706199341656840R1-R18), [[2]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-2c2090344d8cad465e9a858e8383d7a506938c8f3a786afe568ddf7f4ce4c8b8R10))

Data Population Enhancements:

• Updated the populate_all_data.py script to:
  • Add SKUs to products during data generation.
  • Dynamically create warehouses with capacities.
  • Generate inventory and simulate transactions (incoming and outgoing) for each product in each warehouse. ([[1]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-03a41d585e4f174dcb50486546917cd35cf23d52cd03c52547fdc300f2967516R5-R23), [[2]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-03a41d585e4f174dcb50486546917cd35cf23d52cd03c52547fdc300f2967516L31-R114))

API Improvements:

• Enhanced the product_stock_summary API to use product_SKU for product lookup and include SKU in the response. ([warehouse_managment/product/views.pyL78-R95](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-e666d50864fb13751dbf7b4f6e89c0c2b92d9cdc3702b6f34a6096e0d59c4a22L78-R95))
• Improved the warehouse_inventory_list API to:
  • Require warehouse_id as a parameter.
  • Return detailed inventory information, including supplier names, stock levels, and last restocked date. ([warehouse_managment/warehouse/views.pyL26-R61](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-671864e5ab4b2391fe05a8dc9ccf465183a73d48ddde61151f6e247ce13727f9L26-R61))

Development Environment Configuration:

• Added a docker-compose.yml file to set up a development environment with pgadmin, a PostgreSQL client, and a custom network. ([database/docker-compose.ymlR1-R34](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-e0bbebfdf7f802db10750776ed72a77e6ec3e6049c211d039dda66b2bac04470R1-R34))
• Enabled Cross-Origin Resource Sharing (CORS) by adding the corsheaders package and middleware, allowing all origins. ([[1]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-ec23290768da4a8b3ede4e6320a9d220db0548118f69f62e69d882f4dee0d81bR51), [[2]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-ec23290768da4a8b3ede4e6320a9d220db0548118f69f62e69d882f4dee0d81bR62-R66))

Utility Additions:

• Introduced a supplier_names.py utility to map supplier IDs to human-readable names, improving code readability and API responses. ([[1]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-a84939202dc45597ccf0f61f6ade6d7c21a0b4b94c65256659c8b060bdee6c2eR1-R9), [[2]](https://github.com/IASSCMS/Warehouse-Management-Services/pull/21/files#diff-671864e5ab4b2391fe05a8dc9ccf465183a73d48ddde61151f6e247ce13727f9R10))
