我使用Node.js和Mongoose从JSON文件填充MongoDB中的引用集合
$ npm run styles
页面是从JSON文件很好地创建的,并且“站点”文档中的页面字段已填充但我只有一个ID。我的意思是我的JSON文件有2页,所以我得到
页面:“_ id123456”,“_ id123456”来自
var UserSchema = new Schema({
username: String,
sites : [{type: mongoose.Schema.Types.ObjectId, ref: 'Site' }],
});
var SiteSchema = new Schema({
user : { type: String, ref: 'User' },
siteTitle: String,
pages : [{type: mongoose.Schema.Types.ObjectId, ref: prefix + 'Page' }],
});
var PageSchema = new Schema({
site: { type: String, ref: 'Site' },
title: String,
});
exports.create = function(req, res, next) {
var user = new User(req.body);
user.save(function(err) { // create user
if (err) {
return next(err);
} else {
var site = new Site({user: user.username, siteTitle: user.username});
site.save(function(err) { // create website
if (err) {
return next(err);
} else {
user.sites.push(site); // push site'id in sites field in user
user.save(); // save user after site'id has been push
for (var i=0; i<basePages.length; i++) { // create pages from base.json file
var page = new Page(basePages[i]);
page.save(function(err) { // create page
if (err) {
return next(err);
} else {
site.pages.push(page);
site.save();
}
});
res.json(user);
}
}
});
};
});
};
答案 0 :(得分:0)
这是我发现自己的解决方案:)只需在page.save函数中添加页面作为参数;
exports.create = function(req, res, next) {
var user = new User(req.body);
user.save(function(err) { // create user
if (err) {
return next(err);
} else {
var site = new Site({user: user.username, siteTitle: user.username});
site.save(function(err) { // create website
if (err) {
return next(err);
} else {
user.sites.push(site); // push site'id in sites field in user
user.save(); // save user after site'id has been push
for (var i=0; i<basePages.length; i++) { // create pages from base.json file
var page = new Page(basePages[i]);
page.save(function(err, **page**) { // create page
if (err) {
return next(err);
} else {
site.pages.push(**page**);
site.save();
};
});
};
res.json(user);
};
});
};
});
};
