在django中使用gmail api

我对Django有点陌生，需要一些帮助将我的python脚本（身份验证、构建gmail服务、查询gmail）翻译成Django应用程序。我试图使用GoogleDjango示例和它们在这里指定的类，但有点困惑。任何帮助都将不胜感激！当我访问我的索引时，下面的代码使我通过身份验证流程，但是在单击我的google个人资料后，生成的页面是一个错误：

“ValueError at/app/

无法分配None:“CredentialsModel.id”不允许空值

查看代码：

CLIENT_SECRETS = os.path.join(os.path.dirname(__file__), '..', 'client_secret.json')
REDIRECT_URI = 'http://localhost:8080/'
SCOPES = [
'https://www.googleapis.com/auth/gmail.modify',
]


def index(request):
    storage = Storage(CredentialsModel, 'id', request.user.id, 'credential')
    credentials = storage.get()

    flow = flow_from_clientsecrets(CLIENT_SECRETS, scope=SCOPES)
    http = httplib2.Http()

    if credentials is None or credentials.invalid:
        credentials = run(flow, storage, http=http)

    # Authorize the httplib2.Http object with our credentials
    http = credentials.authorize(http)

    # Build the Gmail service from discovery
    gmail_service = build('gmail', 'v1', http=http)

    # then do something, query threads, messages, etc, 
    and return them to a template - not sure where exactly to put the methods for querying     threads, messages, etc.

型号：

from django.db import models

import pickle
import base64

from django.contrib import admin
from django.contrib.auth.models import User
from django.db import models

from oauth2client.django_orm import FlowField
from oauth2client.django_orm import CredentialsField


class CredentialsModel(models.Model):
  id = models.ForeignKey(User, primary_key=True)
  credential = CredentialsField()


class CredentialsAdmin(admin.ModelAdmin):
  pass


admin.site.register(CredentialsModel, CredentialsAdmin)

1） 这一部分完全有问题：

class CredentialsModel(models.Model):
  id = models.ForeignKey(User, primary_key=True)
  credential = CredentialsField()

如果你想与用户模型建立1-1关系，你可以使用

user = models.OneToOneField(User, primary_key=True)

2） 您必须将此部分分离到一个新的admin.py文件中，以避免将来出现问题

class CredentialsAdmin(admin.ModelAdmin):
  pass


admin.site.register(CredentialsModel, CredentialsAdmin)

3） 问题来自这里：

storage = Storage(CredentialsModel, 'id', request.user.id, 'credential')

用户id！=用户

正确的一点是：

storage = Storage(CredentialsModel, 'id', request.user, 'credential')

谢谢-我不得不将存储中的“id”更改为“用户”，但它看起来起作用了。

storage = Storage(CredentialsModel, 'id', request.user, 'credential')
