Error Trying to Import JSON to Django Database - TypeError: 'instancemethod' object has no attribute '__getitem__'

Error Trying to Import JSON to Django Database - TypeError:
'instancemethod' object has no attribute '__getitem__'

I've been self-teaching myself programming for less than a month. I'm
trying to build a Django site to help the process. I've spent the last 3
days searching for a solution to this problem to no avail.
I stole this code from someone on Github, and it works fine when calling
the JSON URL file for which it was specifically written. But I've been
trying to modify it to work with another JSON URL file and it's not
working. It's a command file that is used to import data into the
database. So here's what happens when I run the command:
PS C:\django-1.5.1\dota\mysite> python manage.py update_items
Fetching item list..
<bound method classobj.get_item_list of <class
items.utils.api.SteamWrapper at 0x02981D50>>
TypeError: 'instancemethod' object has no attribute '__getitem__'
I apologize if there is too much code below, I really don't know what
kinds of things people would already implicitly know. I'm trying to import
the fields from each game item listed in this JSON file. I'm just starting
with 2 fields to try to get this working.
You can view the JSON file from the URL below, but it is formatted like this:
{
"itemdata": {
"blink": {
"id": 1,
"img": "blink_lg.png",
"dname": "Blink Dagger",
"qual": "component",
"cost": 2150,
"desc": "Active: Blink - Teleport to a target point up to 1200
units away. If damage is taken from an enemy hero, Blink Dagger
cannot be used for 3 seconds.",
"attrib": "",
"mc": 75,
"cd": 12,
"lore": "The fabled dagger used by the fastest assassin ever to
walk the lands.",
"components": null,
"created": false
},
"blades_of_attack": {
"id": 2,
And here are the 4 files related to the command file update_items.py:
models.py -- this model defines the database fields
from django.db import models
class Item(models.Model):
unique_id = models.IntegerField(unique=True)
dname = models.CharField(max_length=255)
def __unicode__(self):
return self.dname
update_items.py -- this is the command file to import the json data into
the database
from django.core.management.base import BaseCommand, CommandError
from django.core.management.base import NoArgsCommand
from items.utils.api import SteamWrapper
from items.models import Item
class Command(NoArgsCommand):
help = 'Fetches and updates the items'
def update_item(self, item):
try:
db_item = Item.objects.get(unique_id=item['id'])
print 'Updating %s..' % item['dname']
except Item.DoesNotExist:
print 'Creating %s..' % item['dname']
db_item = Item()
db_item.unique_id = item['id']
db_item.dname = item['dname']
db_item.save()
print 'Done.'
def fetch_items(self, result):
try:
for item in result['itemdata']:
self.update_item(item)
except KeyError:
print "Error while contacting steam API. Please retry."
def handle(self, *args, **options):
self.stdout.write('Fetching item list..')
result = SteamWrapper.get_item_list
self.fetch_items(result)
self.stdout.write('Finished.')
api.py -- this is the web api call function thing
import requests
from mysite import settings_local
class SteamWrapper():
''' Steam API wrapper '''
API_KEY = settings_local.STEAM_API_KEY
@classmethod
def _item_send_request(cls, endpoint, *args, **kwargs):
params = {'key': cls.API_KEY}
params.update(kwargs)
request = requests.get(endpoint, params=params)
return request.json()
@classmethod
def get_item_list(cls):
return cls._item_send_request(settings_local.DOTA2_ITEM_LIST_ENDPOINT)
local-settings.py
DOTA2_ITEM_LIST_ENDPOINT = 'http://www.dota2.com/jsfeed/itemdata'
So any ideas? Thanks so much...
