Django測試錯誤AttributeError：'元組'對象沒有屬性'setdefault'

Question

我試圖在django中放置在測試文件夾中的測試。以下是輸出。

python manage.py test

有人能幫助我嗎？ 我試着通過檢查環境來解決問題，我認爲它是正確的。測試在生產環境中運行良好，具有相同的環境。

數據庫設置：

DATABASES = { 
'default': { 
    'ENGINE': 'django.db.backends.postgresql_psycopg2' 
    'NAME': 'projectx',   
    'USER': 'xyz', 
    'PASSWORD': 'xyz', 
    'HOST': '127.0.0.1', 
    'PORT': '',   
} 
} 
if 'test' in sys.argv: 
DATABASES['default'] = { 
    'ENGINE': 'django.db.backends.postgresql_psycopg2', 
    'NAME': 'test_project', 
    'USER': 'xyz', 
    'PASSWORD': 'xyz', 
    'HOST': '127.0.0.1', 
    'PORT': '',   
},

你有你的測試數據庫字典，它把它變成一個單項元組結束後流浪逗號。刪除最後的逗號。
