我有一个三级深度的数据模型.
var job = mongoose.Schema({
id:Number,
jobName:String
});
var demo = mongoose.Schema({
id:Number,
demoName:String,
job:[job]
});
var ExerciseSchema = mongoose.Schema({
id:Number,
name:String,
area:String,
medicalObj:[demo]
});
var Exercise = mongoose.model(‘Exercise’, ExerciseSchema);
我想在第二个嵌套数组中推送新对象
我正在尝试这种方式,但没有工作:
Exercise.update({'area':area},{$push:{"medicalObj.job":{jobName:'Andrea'}}},{upsert:true},function(err){
if(err){
console.log("ERROR" + err);
}else{
console.log("Successfully");
}
});
最佳答案 有一件事我想注意:medicalObj将是一个对象数组.我认为你想要将jobName:andrea添加到job中包含的特定数组中,所以这就是我在测试中所做的:
Exercise.findOne({area: area}, function(e,r){
r.medicalObj.forEach(function(demo){
// the following line looks for the specific array to add jobName Andrea to.
if (demo.demoName == "test") {
demo.job.push({jobName: "Andrea"});
r.save(function(err, res){
console.log(err, res);
});
});
});
如果您只想插入jobName:“Andrea”,如果它不存在,您可以轻松地添加以下行的检查:
Exercise.findOne({area: area}, function(e,r){
r.medicalObj.forEach(function(demo){
if (demo.demoName == "test") {
var found = false;
demo.job.forEach(function(jobs){
if (jobs.jobName == "Andrea") found == true;
});
if (found == false) {
demo.job.push({jobName: "Andrea"});
r.save(function(err, res){
console.log(err, res);
});
};
};
});
});
