我对Python / Django很陌生：
我已经单独测试了Google Sheets API，并且可以正常工作。稍加修改，就将其放入模型中，如下所示：
from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/spreadsheets.readonly']
# The ID and range of a sample spreadsheet.
SAMPLE_SPREADSHEET_ID = '1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms'
SAMPLE_RANGE_NAME = 'Class Data!A2:E'
def mainLoop():
"""Shows basic usage of the Sheets API.
Prints values from a sample spreadsheet.
"""
creds = None
# The file token.pickle stores the user's access and refresh tokens, and is
# created automatically when the authorization flow completes for the first
# time.
if os.path.exists('token.pickle'):
with open('token.pickle', 'rb') as token:
creds = pickle.load(token)
# If there are no (valid) credentials available, let the user log in.
if not creds or not creds.valid:
if creds and creds.expired and creds.refresh_token:
creds.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(
'credentials.json', SCOPES)
creds = flow.run_local_server(port=0)
# Save the credentials for the next run
with open('token.pickle', 'wb') as token:
pickle.dump(creds, token)
service = build('sheets', 'v4', credentials=creds)
# Call the Sheets API
sheet = service.spreadsheets()
result = sheet.values().get(spreadsheetId=SAMPLE_SPREADSHEET_ID,
range=SAMPLE_RANGE_NAME).execute()
values = result.get('values', [])
#####################################################
## REMOVED THESE LINES FROM SAMPLE CODE FROM GOOGLE

#if not values:
# print('No data found.')
#else:
# print('Name, Major:')
# for row in values:
# Print columns A and E, which correspond to indices 0 and 4.
# print('%s, %s' % (row[0], row[4]))
#if __name__ == '__main__':
# main()
并且我已经在我的视图中放置了以下内容：
from django.shortcuts import render
from django.views import generic
from django.http import HttpResponse
from .models import mainLoop
from django.views.generic import ListView
def index2(ListView):
model = mainLoop
return render('', 'index.html')
这是我的html模板：
<html>
<title></title>
<head></head>
<body>
<h1>Spreadsheet</h1>
{% for row in values %}
<div>
{% row %}
</div>
</body>
</html>
我收到以下错误：

我在这里做错了什么？有人可以指出正确的方向吗？非常感谢。
您在Jinja中缺少endfor标签
<html>
<title></title>
<head></head>
<body>
<h1>Spreadsheet</h1>
{% for row in values %}
<div>
{% row %}
</div>
{% endfor %} <!-- <<<<<<<<<<----------- Add this Line-->
</body>
</html>
