settings.DATABASES配置不正確。請提供姓名值

我知道以前有人問過類似的問題。但這都是關於發動機的價值。是否有人知道我如何使用NAME值解決這個錯誤？我部署到heroku，一切正常。然而，在當地，它給了我這個錯誤這裏是回溯：settings.DATABASES配置不正確。請提供姓名值

，這裏是我的setting.py

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

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

DATABASES['default']['ENGINE'] = 'django_postgrespool'

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

就足夠了。如果你想使用django_postgrespool，你可以在上面編輯它。

您此行：

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

只是簡單地覆蓋上述標準DATABASE設置。

它的工作原理。但我更喜歡在開發和生產中使用相同的數據庫。有另一種方法嗎？這讓我感到困惑，因爲我的DATABASE_URL包含用戶名，密碼和數據庫名稱，dj_database_url只是無法獲取數據庫名稱 – JSNoob

只需設置'DATABASE'不會讓您在開發和生產中使用相同的數據庫？我這樣做，它的工作 – shellbye

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

import dj_database_url 

db_config = dj_database_url.config() 
if db_config: 
    DATABASES['default'] = db_config
