Getting error in: items = [item for item in body.items()]

I just want to add multiple orderitems.

I don't know this loop will work after this error.

But atleast you will understand my requirement

I am giving following data:

[
    {
        "service_id": 1,
        "quantity": 2,
        "price": 20
    },
    {
        "service_id": 2,
        "quantity": 3,
        "price": 20
    },
    {
        "service_id": 3,
        "quantity": 4,
        "price": 20
    }
]

CodePudding user response：

You already have

 data = json.loads(request.body)

so I think you should use:

items = [item for item in data.items()]
