我有一个应用程序引擎应用程序,我在上面标记了我的每月支出以及一些评论或原因。我想将这些数据导出到 Google Drive Spreadsheet中。我使用 Django 框架。

我已经阅读了谷歌在这里提供的教程。但是他们已经使用 webapp2 和 jinja 实现了它。此外,Implementing Using Django的文档似乎太过时了,因为我不使用 Django ORM。

下面是我用来上传的代码示例。如果我在下面粘贴的内容是垃圾,我深表歉意。请帮忙。

from django.utils.datastructures import SortedDict
import os
from apiclient.discovery import build
from apiclient.http import MediaFileUpload
from oauth2client.appengine import OAuth2DecoratorFromClientSecrets

decorator = OAuth2DecoratorFromClientSecrets(os.path.join(os.path.dirname(__file__ ),    'clientSecrets.json'), 'https://www.googleapis.com/auth/drive')
drive_service = build('drive', 'v2')

class Exporter(object):
    serializedObjects = []
    mime_type = 'text/plain'
    fileToExport = None
    request = None

    def __init__(self, serializedObjects, request):
        self.serializedObjects = serializedObjects
        self.request = request

    def createCSV(self):
        import csv
        import StringIO

        stdout = StringIO.StringIO()
        writer = csv.writer(stdout)
        for obj in self.serializedObjects:
            for value in obj.values():
                writer.writerow([value])
        # I will get the csv produced from my datastore objects here.
        # I would like to upload this into a Google Spreadsheet.
        # The child class ExportToSpreadSheet tries to do this.
        return stdout.getvalue()

class ExportToSpreadSheet(Exporter):

    def __init__(self, *args, **kwargs):
            super(ExportToSpreadSheet, self).__init__(*args, **kwargs)
            self.mime_type = 'application/vnd.google-apps.spreadsheet'

    def create(self):
            import datetime

            valueToDrive = self.createCSV()
            media_body = MediaFileUpload(valueToDrive, mimetype=self.mime_type, resumable=True)
            body = {
        'title' : 'MyExpense_%s' % datetime.datetime.now().strftime('%d_%b_%Y_%H_%M_%S'),
        'description' : '',
        'mimeType' : self.mime_type
            }
            self.fileToExport = drive_service.files().insert(body=body, media_body=media_body, convert=True)
            return self.fileToExport

    @decorator.oauth_aware
    def upload(self):

            if decorator.has_credentials():
                    self.create()
                    self.fileToExport.execute(decorator.http())
                    return self.fileToExport
            raise Exception('user does not have the credentials to upload to google drive.')

@decorator.oauth_aware仅适用于 webapp.RequestHandler 子类。为什么我这么说是因为我在运行代码时遇到了这个错误。

由于我使用的是 Django 框架,因此我无法获得请求处理程序,因为它们除外。

我如何在我的场景中集成或执行它?我非常感谢我可能错过的任何代码示例或相关链接。

此外,整个事情都发生在一个ajax调用中。

提前致谢。

使用mimeType=text/csv和 在上传期间,请求从 csv 到电子表格的转换:

drive_service.files().insert(covert=True, body=body, media_body=media_body, convert=True)
