Django 1.11.3無法在postgresql中創建表

Question

我想通過django（版本1.11.3）在postgresql中創建表。我輸入以下信息settings.py

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.postgresql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'. 
     'NAME': 'postgres',      # Or path to database file if using sqlite3. 
     'USER': 'postgres',      # Not used with sqlite3. 
     'PASSWORD': 'password',     # Not used with sqlite3. 
     'HOST': 'localhost',      # Set to empty string for localhost. Not used with sqlite3. 
     'PORT': '5432',      # Set to empty string for default. Not used with sqlite3. 
    } 
} 

但它總是創建SqLite數據庫。任何人都可以回答我？

我會盡量把我的settings.py

Answer 1

你不應該使用默認的PostgreSQL數據庫，而是創建一個新的數據庫。通過命令行登錄您的數據庫比執行>>> CREATE DATABASE yourName

比更新您的settings.py以使用該新數據庫。

DATABASES = { 
    'default': { 
     ... 
     name: 'yourName' 
    } 
} 

現在，你已經通過去你的網站根目錄和打字這樣做了設置初始表...

>>> python manage.py makemigrations 
>>> python manage.py migrate 

現在的表應該顯示在您的新的數據庫。
