Feat: Product Availability

[mukunzidd]

Description

As a vendor, I should be able to mark a product as available or unavailable manually, so that buyers can view and purchase the available products. Products may need to be marked as unavailable due to reasons such as expiry date or out-of-stock situations.

Acceptance Criteria

• [x] Implement an API endpoint for updating product availability
• [x] Validate the requesting user's role as a vendor
• [x] Validate the request payload (product ID, availability status)
• [x] Retrieve the product from the database based on the provided product ID
• [x] Ensure the product belongs to the requesting vendor
• [x] Update the product availability status in the database
• [x] Implement error handling and appropriate response messages for validation failures
• [x] Implement input sanitization

Developer Notes

• Document the API endpoint with Swagger
• Define the request payload structure for updating product availability
• Implement necessary validation checks for the request payload
• Update the product availability status in the database
• Handle scenarios where the product does not exist or does not belong to the requesting vendor
• Write unit tests to cover different scenarios and edge cases
