我想在Ubuntu的数字海洋部署我的第一个rails应用程序,我不确定我是否做这个权利。测试和生产sqllite。在挫折中,我改变了所有我的数据库postgres我更改database.yml。我不确定如果我做到了这一点正确但我有这个错误:ActiveRecord :: StatementInvalid(SQLite3 :: ReadOnlyException:是sqllite。我不知道是否必须告诉服务器切换到生产模式,或者如果它被配置为使用sqllite。ActiveRecord :: StatementInvalid(SQLite3 :: ReadOnlyException:当使用postgres
我想要做的是使用postgres而不是sqllite。我使用nginx和我的数据库是空白的,所以我不需要传输任何东西。我做了postgres da在postgres中,我只需要将我的应用程序指向该数据库即可。 (我不知道如果我需要做些别的事情
我已经使用这个database.yml的

在什么情况下你会得到那个错误?当你尝试启动控制台?运行服务器? – Bryce
当我尝试写入应用程序(发表评论)时发生这种情况:http://104.236.51.180/blogs/10 – applejuiceteaching
您可以运行'rake db:drop db:create db:migrate'吗?你能登录到Rails控制台并通过该接口创建一个Comment对象吗?如果不是,那么错误是什么? – Bryce
