Settings.py 这是设置中的数据库，看起来像......

# DATABASES = {
#     'default': {
#         'ENGINE': 'django.db.backends.sqlite3',
#         'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
#     }
# }

# # always make sure "psycopg2" is installed

try:
    # production database on Heroku
    DATABASES = {
        'default': dj_database_url.config(
            default=config('DATABASE_URL')
        )
    }
except:
    # local database for development

    DATABASES = {  
        'default': {
            'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
            'NAME': config('DB_NAME'),                      
            'USER': config('DB_USER'),                      
            'PASSWORD': config('DB_PASS'),     # remove "password" & add yours
            'HOST': config('DB_HOST'),                      
            'PORT': config('DB_PORT'),                      
        }
    }

manage.py 这是我的 manage.py 的样子...

import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bloverse.settings")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)
