Optimizing Cart Functionality with Caching and Variable Manipulation
In this meeting, the participants discussed an issue with adding items to a shopping cart. The problem was that when adding multiple quantities of the same item, it was adding them as separate items instead of increasing the quantity.
The solution proposed was to store the cart as a JSON object in Redis instead of using a list. This would allow for easier manipulation of the quantity of each item. The participants discussed the logic behind updating the cart and made changes to the code accordingly.
They also addressed the scenario where a user didn't have a cart yet, and added code to handle that situation. Additionally, they discussed the performance implications of the solution and concluded that it was unlikely to be a limiting factor.
Overall, the meeting focused on modifying the code to properly handle adding items to the cart and updating the quantity of existing items.
