是我每次尝试时不断遇到的错误
运行服务器、makemigrations 或 migrate。此外，当我 运行 SELECT * FROM table_name 对于任何 table 它告诉我它不存在。
堆栈溢出并没有真正让我 post 因为我的 post 是 'too much code' 所以 aaaaaaaaaaaaaaaaaaaaaaaa
您可能已经添加了一个新模型 Gallery 但之后您忘记了 运行 makemigrations 和 migrate 在 droplet 上。然后，您向 website/views.py 中的视图函数添加了一些代码，该函数试图从数据库中获取 Gallery 模型，但它们是 non-existing，因此 Django 给出了错误。
要解决此问题，请尝试注释掉使用 Gallery 模型的特定视图函数中的每一行代码，然后 create/run 迁移。
之后你可以取消注释所有使用 Gallery 模型的代码，因为相应的 table 现在存在于数据库中，查询将成功。
