如何让 Django 从 my.cnf 读取 MySQL 密码？

Question

I have a .my.cnf file in my home directory so that, almost all the time, I can access my MySQL databases with just my username.

However, in django, if I remove the password from the configuration in the settings.py, as seen below, the django app cannot access the database.

DATABASES = {
    'default': {
        'NAME': 'calaccess_raw',
        'PASSWORD': 'ZuperZekretPazzword',
        'ENGINE': 'django.db.backends.mysql',
        'USER': 'ray',
        'HOST': 'localhost',
        'PORT': '3306',
        'OPTIONS': {
            'local_infile': 1,
        }
    }
}

It seems insecure that I need to put my password inside the settings.py file. These tend to be included in git repositories and such and it seems a bad idea.

So, is there a way to get the python MySQL driver being used by django to use the standard my.cnf files?

Answer 1

Under 'OPTIONS' you can specify a 'read_default_file' like this:

'OPTIONS': {
    'read_default_file': '/path/to/my.cnf',
},

Give that a try; hope it helps.
