Question

我正在将PyCharm 2018.2与Python 3.7一起使用。我已经在settings.py文件中定义了数据库...

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'mainsite',
        'USER': 'mainsite',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'PORT': '5432'
    }
}

在Mac上使用“ Option + R”，我可以打开“ manage.py”控制台，并在其中运行迁移。我通过运行以下命令来做到这一点。看来成功了...

manage.py@mainsite_project > sqlmigrate mainsite 0002
bash -cl "/Users/davea/Documents/workspace/mainsite_project/venv/bin/python /Applications/PyCharm.app/Contents/helpers/pycharm/django_manage.py sqlmigrate mainsite 0002 /Users/davea/Documents/workspace/mainsite_project"
Tracking file by folder pattern:  migrations
/Users/davea/Documents/workspace/mainsite_project/venv/lib/python3.7/site-packages/psycopg2/__init__.py:144: UserWarning: The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead.

  """)
BEGIN;
--
-- Add field url to article
--
ALTER TABLE "mainsite_article" ADD COLUMN "url" text DEFAULT '' NOT NULL;
ALTER TABLE "mainsite_article" ALTER COLUMN "url" DROP DEFAULT;
COMMIT;
Process finished with exit code 0

但是，当我在本地查看数据库时，我看不到那里的额外列...

mainsite=> \d mainsite_article;

                                     Table "public.mainsite_article"
    Column    |           Type           |                           Modifiers                            
--------------+--------------------------+----------------------------------------------------------------
 id           | integer                  | not null default nextval('mainsite_article_id_seq'::regclass)
 path         | character varying(100)   | not null
 time         | timestamp with time zone | not null
 votes        | integer                  | not null
 comments     | integer                  | not null
 main_page    | boolean                  | not null
Indexes:
    "mainsite_article_pkey" PRIMARY KEY, btree (id)
Referenced by:
    TABLE "mainsite_mainsitestat" CONSTRAINT

我在做什么错了？

为什么我从PyCharm运行的迁移不影响我的本地数据库？
