In Django why the error "TypeError at / string indices must be integers"?-CodePudding

I am trying to learn how to save in Django part of a json content coming from a kraken api. Going through several examples here on stackoverflow i came up with this code:

views.py

from django.shortcuts import render
from meal_app.models import Kraken
import requests

def get_krakens(request):
    all_krakens = {}
    url ='https://api.kraken.com/0/public/Assets' 
    response = requests.get(url)
    data = response.json()

    
    for i in data:
        kraken_data = Kraken(
            name = i['altname']
            )
        kraken_data.save()
        all_krakens = Kraken.objects.all().order_by('-id')

    return render (request, 'krakens/kraken.html', { "all_krakens": 
    all_krakens} )

When i try to run it appears:

How can i solve this error? My json is visible in my console but i cannot access the value 'altname'. Your help would be really appreciated.

            name = i['altname']

On iPad so can’t check but I suspect your ‘i’ is a string and will need to be converted to a Python object/dictionary before you can extract the sub element from it.

Look at the json.loads method in the json module.

CodePudding user response：

Your "i" is in the form of a string. You need to convert it to an object first. Using i = json.loads(i)
