Meteor alanning:roles - 调用方法 'updateRoles' 时出错:内部服务器错误 [500]

Meteor alanning:roles - Error invoking Method 'updateRoles': Internal server error [500]

我正在尝试通过服务器上的方法为登录用户设置角色(使用 alanning:roles 包)。这就是我所拥有的...

客户端

var userId = Meteor.userId();
Meteor.call('updateRoles',userId,'admin');

这是 method from the docs...

的简化版本

server/userMethods.js

Meteor.methods({
    updateRoles: function (targetUserId, roles) {
        Roles.setUserRoles(targetUserId, roles)
    }
})

无论我尝试什么,我都会收到以下错误...

Error invoking Method 'updateRoles': Internal server error [500]

问题已解决。

原因是因为我正在为 'users' 集合使用自动表单(简单模式),我需要在模式中包含以下(未注释的部分)...

// Add `roles` to your schema if you use the meteor-roles package.
// Option 1: Object type
// If you specify that type as Object, you must also specify the
// `Roles.GLOBAL_GROUP` group whenever you add a user to a role.
// Example:
// Roles.addUsersToRoles(userId, ["admin"], Roles.GLOBAL_GROUP);
// You can't mix and match adding with and without a group since
// you will fail validation in some cases.
//
//roles: {
//    type: Object,
//    optional: true,
//    blackbox: true
//},
// Option 2: [String] type
// If you are sure you will never need to use role groups, then
// you can specify [String] as the type

roles: {
    type: [String],
    optional: true
},
