Heroku推送被拒绝(Django app)

Question

我正在将Django应用程序部署到GitHub和Heroku。

我首先将其部署到GitHub，删除(将其放在.gitignore文件中) "settings.py"，现在我正在尝试将其推送到Heroku，我得到了一个错误：

ImportError: No module named settings
remote: 
remote:  !     Error while running '$ python manage.py collectstatic --noinput'.
remote:        See traceback above for details.
remote: 
remote:        You may need to update application code to resolve this error.
remote:        Or, you can disable collectstatic for this application:
remote: 
remote:           $ heroku config:set DISABLE_COLLECTSTATIC=1
remote: 
remote:        https://devcenter.heroku.com/articles/django-assets
remote: 
remote:  !     Push rejected, failed to compile Python app

我如何避免将一些文件推送到GitHub，同时又有可能将其推送到Heroku？

更新：

我试着将settings.py和temp_settings.py分开，但现在这个应用程序不能再工作了。这是我尝试运行本地服务器时的回溯：

Traceback (most recent call last):

    execute_from_command_line(sys.argv)

    self._wrapped = Settings(settings_module)
  File "/home/stefano/projects/blog-project/blogprojectenv/local/lib/python2.7/site-packages/django/conf/__init__.py", line 92, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/home/stefano/projects/blog-project/blogproject/settings.py", line 104, in <module>
    DATABASES['default'].update(db_from_env)
NameError: name 'DATABASES' is not defined

似乎settings.py不能“到达”temp_settings.py，因为我已经在temp_settings中剪切粘贴了所有的数据库设置。这是错的吗？

通常的做法是不忽略代码库中的settings.py文件。相反，你可以这样做：

try:
    from temp_settings import *
except ImportError:
    pass

在settings.py文件的末尾添加temp_settings.py到.gitignore

对于需要保密的凭据，请使用temp_settings。
