我的服务器上有一个rails应用程序，当我执行public class Lot {
public List<Lot> getAllLot(string query) {
dao.getConnection() ;
// Créer une liste pour stockerle résultat
List<Lot> list = new List<Lot> () ;
// ouvre la connection
if (dao.openConnection()== true) {
MySqlConnection connection = new MySql.Data.MySqlClient.MySqlConnection("server=localhost;database=pharmacie;uid=root;pwd=sqlServer12;");
// créer la commande
MySqlCommand cmd = new MySqlCommand (query, connection);
// Créer un data reader et executer la commande
dao.getConnection() ;
// *** The error is "Connection must be valid and open."
MySqlDataReader reader = cmd.ExecuteReader(); // I get error here
// lis les données et les stock dans la liste
while (reader.Read()) {
list.Add(new Lot
{
numLot = reader.GetString (0),
dateFabrication = reader.GetDateTime(1),
dateLivraison = reader.GetDateTime(2),
datePeremption = reader.GetDateTime(3)
});
}
reader.Close();
dao.closeConnection();
}
return list;
}
}
时运行正常，但当我运行rails s -b domain.name或rails s -b domain.name -e production时出现以下错误。
RAILS_ENV=production rails s -b domain.name
的修改
这是导致错误的文件：
=> Booting Puma
=> Rails 4.2.6 application starting in production on http://domain.name:3000
=> Run 'rails server -h' for more startup options
=> Ctrl-C to shutdown server

/home/deploy/appname/app/controllers/users/confirmations_controller.rb错误似乎来自Devise自动生成的文件，但我无法弄清楚为什么它只在生产模式下发生。
答案 0 :(得分：1)
我认为您尝试使用rails generate devise:controllers覆盖设计默认行为，但您可能已经严重更改了它们。
请确保：
controllers/users文件夹（如果您应用的模型名称是Users）controller/users中所有文件的语法。
