Question

在我的meteor.js应用程序中，我正在尝试使用CollectionFS更新组的图片。

var groupimage = Images.insert(file);
Groups.update(groupId, {$set: { photo: groupimage }}, function(error) {
            if (error) {
                // display the error to the user
                throwError(error.reason);
            } else {
                console.log('mongo document new');
                console.log(Groups.findOne({_id:groupId}));

            }
        });

这不起作用，它会出现此错误：

Exception in delivering result of invoking '/groups/update': ReferenceError: throwError is not defined

但是当我插入而不是更新时，一切都运行得很好。这很有效。

 var groupimage = Images.insert(file);
        Groups.insert({
            name: 'My Group',
            photo: groupimage
        });

我的更新有什么问题？谢谢。

Answer 1

您应该使用Meteor的error method代替：

 throw new Meteor.Error(500, error.reason);

在Meteor.js中使用mongo update命令的CollectionFS
