Django Project : 'dict' object has no attribute 'code'

I retrieved a list of products via an API, then I use django-shopping-cart to generate my cart
But I have an error ‘dict’ object has no attribute ‘code’.

the error is at this line : if product.code == code ,while there is indeed the code attribute in the dict

def cart_add(request,code):
url='http://myapi/Product/GetProducts'
x=requests.get(url)
content=x.json()
all_products=content['products']
for product in all_products :
    if product.code == code :
        cart=Cart(request)
        cart.add(product = product.code)
return render(request,'shop/deatil.html')

At the API level, the dictionary specification is of the form:

dict = {
     "products": [
     {
       "code": "4mlk2",
       "designation": "kaka"
     },
     {
       "code": "455ml",
       "designation": "koko"
     },
     ....
    ]
   }
