Question

我有一个用烧瓶创建的Web报告工具，该工具连接到mysql数据库，该数据库全天从电话系统接收数据。我有这个报告工具，可以很好地工作（在刷新屏幕或登录时更新数字。）但是现在，自从我添加了2个查询并稍微更改了代码后，我仍然可以访问该网站，但是不会像以前那样更新其数字。重启我的uwsgi服务和nginx时，这些数字是正确的，但是随着时间的流逝，这些数字不会更新，并且直到服务和nginx重新启动时才打来电话。在部署和服务器维护方面，我是个菜鸟。我不确定是否需要在代码中的某个地方关闭sql连接并再次建立连接，以便我们收到更新的数字？这是我的代码，我将显示uwsgi.py，main.py的某些部分（尤其是在其中添加了2个查询的位置）以及nginx.conf…在这里，您可以... 这只是项目的基本内容。我真的不认为这在我的代码购买中可能是错误的。 Main.py

根据sqlalchemy.engine.Connection的{{3}}：

Connection对象表示从连接池中检出的单个dbapi连接。在这种状态下，连接池不会影响连接，包括连接的到期或超时状态。为了使连接池正确管理连接，每当不使用连接时，应将连接返回到连接池（即connection.close（））。

因此，不要在导入时将其创建为全局对象，而应在每个请求的生命周期内创建和关闭连接。

Flask不从新的SQL数据更新数据-Nginx，Uwsgi，Centos7，Mysql
