我在后端使用 mongoose,想知道像这样设置数组类型的架构属性是否正确?:
comments: {
type: [],
required: false,
}
然后像这样推送到具有相同属性的文档?:
thread.comments.push({
commenter: req.user.username,
content: comment,
});
thread.save();
答案 0 :(得分:1)
由于评论是您的线程架构的子级,我建议使用 SubDocuments:
const commentSchema = new Schema({
commenter: 'string',
content: 'string'
});
const threadSchema = new Schema({
comments: [commentSchema],
//...
});
添加评论:
thread.comments.push({
commentor: req.user.username,
content: comment //the text of the comment
});
thread.save();
