Question

我有一个我构建的应用程序，它在本地计算机上运行完美但是一旦我部署它就会出现500服务器错误。日志打印此错误...

ProgrammingError: relation "land_property" does not exist
LINE 1: ...video", "land_property"."featured_video_url" FROM "land_prop...
                 ^

我认为这是我的postgres数据库的问题，因为我的本地机器运行应用程序与sqlite一样好。

我对编程很新，对django来说是全新的，所以感谢您的帮助

编辑：这是我的models.py

Answer 1

经过多次反复试验后，我终于明白了。我的数据库结构看起来像这样......

if 'RDS_DB_NAME' in os.environ:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql_psycopg2',
            'NAME': os.environ['RDS_DB_NAME'],
            'USER': os.environ['RDS_USERNAME'],
            'PASSWORD': os.environ['RDS_PASSWORD'],
            'HOST': os.environ['RDS_HOSTNAME'],
            'PORT': os.environ['RDS_PORT'],
        }
    }
else:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        }
    }

由于我只在服务器上设置了环境变量，所以它在sqlite db上运行了我的所有迁移。我将环境变量添加到我的本地计算机并重新运行迁移并且它有效。

非常感谢@Exprator的所有输入。

我现在遇到了另一个错误。当我尝试登录django admin时，它说＆＃34; Forbidden＆＃34;。有什么想法吗？

部署django时的ProgrammingError
