在尝试设置Django时出现错误配置（“settings.DATABASES配置不正确”）错误 [英] ImproperlyConfigured("settings.DATABASES is improperly configured. ") error when trying to set up Django

问题描述

试图按照此处的说明在Heroku上设置Django实例。

尽可能安装Celery，直至以下步骤：

  $ python manage.py syncdb 
  

当我收到以下错误：

引发错误配置（settings.DATABASES不正确地配置
。django.core.exceptions.ImproperlyConfigured：
settings.DATABASES配置不正确。请提供ENGINE
值。查看设置文档以获取更多详细信息。

我相信我的 settings.py 文件放在正确的位置（project-name / project-name），我正在运行django 1.4.3，但是当我尝试运行 manage.py diffsettings 时，我得到以下输出：

< BROKER_BACKEND ='dj ango'### DATABASES = {'default'：{'ENGINE'：
'django.db.backends.dummy'，'TEST_MIRROR'：None，'NAME'：''，
'TEST_CHARSET '：None，'TIME_ZONE'：'UTC'，'TEST_COLLATION'：None，
'PORT'：''，'HOST'：''，'USER'：''，'TEST_NAME'：None，'' PASSWORD'：''，
'OPTIONS'：{}}}

绝对不知道 django.db.backends.dummy 条目来自我的 settings.py 具有'ENGINE'：'django .db.backends.postgresql_psycopg2'，我认为这是正确的条目，即使Heroku指令不告诉你在任何时候更新它。

有什么想法我需要在这里编辑？

解决方案

我遇到了同样的问题。在Heroku文档中 https://devcenter.heroku.com/articles/django#prerequisites，它表示将以下内容添加到 settings.py ：

  DATABASES ['default'] = dj_database_url.config（）
  

您可以传入以下参数：

  DATABASES ['default'] = dj_database_url.config（default ='postgres：// user：pass @ localhost / dbname'） 
  

这样可以让您在本地和Heroku上进行开发。实际上解决了我遇到的问题的部分是DATABASE_URL的Heroku配置环境变量没有实际设置。为了设置这个，我跑了

  $ heroku config 
  

我看到分配给单独配置变量的数据库URL。所以我创建了一个新的变量：

$ $ $ $ $ $ $ $ $ $ $ code>

解决了我的问题。我希望它能帮助其他有类似问题的人。

Attempting to follow the instructions here to set up a Django instance on Heroku.

Got as far as the installation of Celery, up to the following step:

$ python manage.py syncdb

when I get the following error:

raise ImproperlyConfigured("settings.DATABASES is improperly configured. "django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

I believe that I have my settings.py file in the right place (project-name/project-name), and I'm running django 1.4.3, but when I try to run manage.py diffsettings, I get the following output:

BROKER_BACKEND = 'django' ### DATABASES = {'default': {'ENGINE': 'django.db.backends.dummy', 'TEST_MIRROR': None, 'NAME': '', 'TEST_CHARSET': None, 'TIME_ZONE': 'UTC', 'TEST_COLLATION': None, 'PORT': '', 'HOST': '', 'USER': '', 'TEST_NAME': None, 'PASSWORD': '', 'OPTIONS': {}}}

Absolutely no idea where the django.db.backends.dummy entry comes from, my settings.py has 'ENGINE': 'django.db.backends.postgresql_psycopg2', which I assume is the correct entry even though the Heroku instructions don't tell you to update it at any point.

Any thoughts what I need to edit here?

解决方案

I ran into the same issue. In the Heroku docs at https://devcenter.heroku.com/articles/django#prerequisites, it says to add the following to settings.py:

DATABASES['default'] =  dj_database_url.config()

You can pass in a parameter of:

DATABASES['default'] =  dj_database_url.config(default='postgres://user:pass@localhost/dbname')

And that will allow you to develop locally and on Heroku. The part that actually SOLVES the problem I had though was that the Heroku config environment variable of DATABASE_URL was not actually set. To set this, I ran

$ heroku config

I saw the Database URL assigned to a separate config variable. So I created a new variable:

$ heroko config:add DATABASE_URL={#the database url}

That solved my problem. I hope it helps anyone else with similar issues.
