DJANGO/Heroku没有保存到数据库POSTGRES

Question

我正在创建一个API，我的应用程序没有将用户信息保存到POSTGRES数据库。有人可以看看我的代码，并告诉我什么是错的？

尝试时，我也得到一个的accessToken错误信息去cr吃掉一个。我真的被困住了，我不知道该从哪里出发。

谢谢

Answer 1

所以我想通了。它与创建我的client_id和client_secret令牌有关。 Heroku生成的client_id和client_secret令牌有时不会生成。所以你需要做的就是进入你的django管理员并创建一个新的应用程序。使用以下设置： 客户类型：保密或公开 授权拨款类型：授权码 名称：服务的名称（在我的情况脸谱）

这会给你的CLIENT_ID和client_secret令牌，但他们将只如果工作你点击submit来创建应用程序。完成之后，您的API将能够与您的应用程序进行通信。

Answer 2

你的设置没有提到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'), 
    } 
} 

您应该遵循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)
