E-commerce project with Python

Today, on the forty-third day of our Python learning journey, we're diving back into our e-commerce project. I'm excited to share that I've completed the remaining APIs for the cart feature, bringing us one step closer to a fully functional system.

Task done by today:

Bulk API: This API is to get products by IDs and these IDs we are providing in params.

 @product_router.get("/products/bulk",response_model=List[Product])
 async def getBulkProducts(ids: str = Query(...)):
     try:
         ids_list = ids.split(',')
         products = []
         for id in ids_list:
             product = await get_product_collection().find_one({"id": int(id)})
             if product:
                 products.append(product)
         return products;
     except:
         print('An exception occurred')

Cart APi: we have two APIs for the cart first one is to create and update the cart and the second is to get a cart.

To create cart:

 @cart_router.post("/carts")
 async def saveCart(request: Request, new_cart: Cart_Type):
     if "Authorization" not in request.headers:
         raise HTTPException(status_code=401, detail="Unauthorized")

     token = request.headers["Authorization"]
     print("data: ", dict(new_cart.data))

     try:
         payload = dict(verify_token(token))
         user_email = payload.get("email")
         collection = get_cart_collection()

         # Check if cart already exists for the user
         existing_cart = await collection.find_one({"user_email": user_email})

         if existing_cart:
             # Update existing cart
             await collection.update_one({"user_email": user_email}, {"$set": {"cart": json.dumps(new_cart.data)}})
         else:
             # Create new cart
             cart_data = {
                 "user_email": user_email,
                 "cart": json.dumps(new_cart.data)
             }
             await collection.insert_one(cart_data)

         return {"message": "Cart updated successfully"}
     except Exception as e:
         raise HTTPException(status_code=401, detail="Invalid token")

For getting the cart:

 @cart_router.get("/carts", response_model=List[Cart_Response])
 async def getCart(request: Request):
     if "Authorization" not in request.headers:
         raise HTTPException(status_code=401, detail="Unauthorized")
     token = request.headers["Authorization"]
     try:
         payload = dict(verify_token(token))
         user_email = payload.get("email")
         collection = get_cart_collection()
         product_collection = get_product_collection()
         # Check if cart already exists for the user
         existing_cart = await collection.find_one({"user_email": user_email})
         products = []
         if existing_cart:
             # Update existing cart
             cart_str = existing_cart.get("cart")
             cart_obj = json.loads(cart_str)
             ids = list(cart_obj.keys())
             for id in ids:
                 product = await product_collection.find_one({"id": int(id)})
                 product_object = { "product": product, "quantity": cart_obj[id] }
                 products.append(product_object)
         return products
     except Exception as e:
         raise HTTPException(status_code=500, detail="something went wrong")

In upcoming blogs, we'll optimize these APIs according to best practices, ensuring they are efficient and follow industry standards for robustness and scalability in our e-commerce project.
