问题 I am writing a unit test that needs to access an image file that I put in "fixtures" directory right under my django app directory.

I cannot use the "regular" way to set the database settings with a dictionary because my database url comes from an environment variable. Thx in advance! 回答1: You could update your settings afterwards: DATABASES['default']['OPTIONS'
