我有以下方案:
dGroup = new SimpleSchema({
title: { type: String, optional: true },
element: { type: String, optional: true }
});
MongoDB.attachSchema(new SimpleSchema({
title: { type: String },
slug: { type: String, unique: true },
language: { type: String, defaultValue: "en" },
group: { type: [dGroup], optional: true },
}));
......在DB中我得到了这个:
{ "_id" : "ag9qXWpCYm87kZbEk", "title" : "Test", "slug" : "test", "language" : "en" }
现在我要添加一个dGroup - >标题:
updates['group.title'] = 'insert this as a new group title with no element';
MongoDB.update({ _id: Id }, { $push: updates }, function(error) { if(error) console.warn(error); });
但这不起作用。所以我需要一些帮助来在流星中添加子文档,以防它们不存在。
答案 0 :(得分:1)
首先尝试声明对象并正确推送它,如下所示:
var newGroup = {
title: 'insert this as a new group title with no element'
};
MongoDB.update({ _id: Id }, { $push: {group: newGroup }}, function(error) { if(error) console.warn(error); });
