[mukunzidd]

Description:

The backend needs to handle the addition of items to the buyer's wishlist, including storing the wishlist in the buyer's account and sending a confirmation message to the frontend.

Acceptance Criteria:

• Implement a POST request endpoint to add an item to the buyer's wishlist.
• When a POST request is made:
• The item should be added to the buyer's wishlist.
• The product details (name, price, image) should be retrieved from the database.
• The updated wishlist should be stored with the buyer's entity and have a relationship with the buyer.
• A confirmation message should be sent to the frontend to be displayed to the buyer.

Developer Notes:

• Validate that the buyer is logged in before processing the request.
• Implement logic to add the item to the buyer's wishlist.
• Retrieve the product details from the database based on the item being added.
• Store the updated wishlist in the buyer's account entity.

Can you use the Eraser for ERD to show relationship between product, user and wishlist !
Also it's better to make Acceptance criteria in checkboxes . otherwise all is good.Apply the feedbacks
