我正在创建 API，但我的应用没有将用户信息保存到 POSTGRES 数据库。有人可以查看我的代码并告诉我有什么问题吗？

            Profile.objects.create(user_id=user.id, age_min=age_min, age_max=age_max, gender=gender, avatar=avatar, lifestyle_info=lifestyle_info)

当它尝试创建一个 AccessToken 时，我也会收到一条 AccessToken 错误消息。我真的被困住了，我不知道从这里去哪里。

谢谢

【问题讨论】：

您的设置似乎没有任何问题。您可以发布您的完整回溯吗？
@ChidG 我已经用完整的回溯更新了帖子。

标签： django postgresql heroku

【解决方案1】：

您的设置没有提到 PostgresSQL。他们只指定一个 sqlite3 数据库。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

您应该关注instructions并添加：

# Parse database configuration from $DATABASE_URL
import dj_database_url
...
db_from_env = dj_database_url.config(conn_max_age=500)
DATABASES['default'].update(db_from_env)

【讨论】：

对。那么你能包含更新数据库的实际代码吗？
是的，我现在更新了。此外，当我发出 curl 请求以撤销令牌时，它一直告诉我我的 client_id 参数无效。会是这样吗？
这只是配置。 OAuth 和所有令牌与无法写入数据库有什么关系？
我不知道。我只是在克隆某人的 git。您是否想查看 git 文件，以便它们可以让您更好地了解正在发生的事情？ link

【解决方案2】：

所以我想通了。它与我的 client_id 和 client_secret 令牌的创建有关。有时 Heroku 生成的 client_id 和 client_secret 令牌不会生成。因此，要解决此问题，您必须进入 django 管理员并创建一个新应用程序。使用以下设置：客户类型：机密或公开授权授予类型：授权码名称：服务名称（在我的例子中是 Facebook）

这将为您提供 client_id 和 client_secret 令牌，但它们仅在您单击提交创建应用程序时才有效。完成后，您的 API 将能够与您的应用程序通信。
