django.core.exceptions.ImproperlyConfigured：settings.DATABASESが正しく設定されていません。 ENGINEの値を指定してください

Question

私はDjangoを使用するWebアプリケーションを構築しています。

API呼び出しを使用してデータを取得し、それをデータベースに挿入してWebページに表示することが目的の1つです。

私はデータを取得できますが、データベースに挿入する際に問題が発生しています。

私はエラー

がdjango.core.exceptions.ImproperlyConfigured取得しようとするたび：settings.DATABASESが不適切に設定されています。 ENGINE値を入力してください。詳細については、設定文書を確認してください。

私は他の人から与えられた指示に従っており、私は運がなかった。

これは、問題のDEFである：

import requests 
from django.conf import settings 
settings.configure() 
from polls.models import Poll 

def getSnacks(): 

    response = requests.get('https://api-snacks.nerderylabs.com/v1/snacks?ApiKey=xxxxxxxxxxxxxxxxxxx') 


    print("adding to DB") 
    html = response.json() 
    snackArray = [] 
    x = 0 
    p = Poll.objects.get(pk=1) 

    while x < len(html): 
     snackArray.append(html[x]) 
     x += 1 

    for y in snackArray: 
     print("uploading " + y["name"]) 
     snackID = y["id"] 
     snackName = y["name"] 
     snackOp = y["optional"] 
     snackLoc = y["purchaseLocations"] 
     snackCnt = y["purchaseCount"] 
     snackPrchDt = y["lastPurchaseDate"] 


     p.snacks_set.create(name=snackName,source_ID=snackID,optional=snackOp,purchaseLocation=snackLoc,purchaseCount=snackCnt,lastPurchaseDate=snackPrchDt,votes=0)

あなたsettings.pyの上部にdj_database_urlをインポートするので、あなたはDJ-Database-URLを使用しているように見えます。そのパッケージに必要な環境変数を定義するか、そのインポート行を削除して標準のDjango設定形式を使用してください。
