我正在使用Upsert gem和Rails 4.2.1以及mysql2 gem v0.3.18。但是每当我尝试插入任何东西时，我都会收到“拒绝访问”错误。
例如：
upsert = Upsert.new User.connection, User.table_name
似乎工作正常。
但是当我真的尝试使用Upsert时，就像这样：
upsert.row({id: 123}, name: 'Neat')
我收到此错误：
Mysql2::Error: Access denied for user 'developer'@'%' to database 'project_development'

我之前使用过PostgreSQL使用Upsert，它运行得很漂亮。有没有其他人在使用MySQL和Upsert之前看到过这个错误，如果有的话，你有什么建议吗？
答案 0 :(得分：1)
希望这有助于其他人......但事实证明，＆＃34;开发人员＆＃34;用户没有该MySQL数据库的 CREATE PROCEDURE 权限。
将这些权限授予＆＃34;开发人员＆＃34;用户，事情只是膨胀。
