Error while saving a Document in MongoDB while using plugin mongoosastic

Question

my elastic search service working fine . And I am using mongoosastic for inserting in Elastic Search

This is the code I use

var mongoose = require('mongoose')
, mongoosastic = require('mongoosastic')
, Schema = mongoose.Schema

var User = new Schema({
name: String
, email: String
, city: String
})

var userModel=mongoose.model("userModel",User)

User.plugin(mongoosastic)

mongoose.connect("mongodb://localhost/myapp" ,function(err) {
if (err) throw err;

var user=new userModel()
user.name="Abhay"
user.save(function(err,user){
    console.log("err is ",err)
    console.log("user is ",user)
})
})

This produce this error

Note If I comment or remove User.plugin(mongoosastic) then Document save into collection successfully

Answer 1

You simply need to move User.plugin(mongoosastic) above the mongoose.model() line

...
var User = new Schema({
name: String
, email: String
, city: String
})

User.plugin(mongoosastic)          <---- move this line up here

var userModel=mongoose.model("userModel",User)
...
