Question

我创建了一个只包含一个变量权限的Role类：

class Role {
    String authority
}

现在，当我尝试在BootStrap.groovy（grails app）中保存新值时，我这样做：

def adminRole = Role.findOrCreateWhere(authority: "ROLE_ADMIN");

当我运行时，我遇到以下异常：

我的代码出了什么问题？

谢谢！

Answer 1

试试这个：def adminRole = Role.findOrCreateWhere（[authority：“ROLE_ADMIN”]）;

找不到方法 - findOrCreateWhere - gorm
