I wanted to use more than one schema per collection in mongodb , how to use it....?

It gives me this error when I try to run it:

Error:

OverwriteModelError: Cannot overwrite allUsers model once compiled.

OverwriteModelError: Cannot overwrite checkInOut model once compiled.

Heres my schema.js

var mongoose = require('mongoose'); var Schema = mongoose.Schema , ObjectId = Schema.ObjectId; var checkInInfoSchema= new Schema({ name:String, loginSerialId:Number }); var loginUserSchema = new Schema({ sn : { type: Number, unique:true } ,uname: {type:String, unique:true} ,pass:String }); var registerUserSchema = new Schema({ sn : { type: Number, unique:true } , name: String //his/her name ,pass:String, companyKey:{type:String}, uname:{type:String,unique:true} }); var checkInOutSchema = new Schema({ uname: String ,companyKey:String ,task:String ,inTime:String ,outTime:String ,date:{type:String} ,serialId:{type:Number,unique:true} ,online:Boolean }); //Different schema for same collection "allUsers" var allUser=mongoose.model('allUsers',loginUserSchema); var registerUser=mongoose.model('allUsers',registerUserSchema); //Different schema for same collection "checkInOut" var checkInOut=mongoose.model('checkInOut',checkInOutSchema); var checkInInfo=mongoose.model('checkInOut',checkInInfoSchema); module.exports={ allUser:allUser, registerUser:registerUser, checkInOut:checkInOut, checkInInfo:checkInInfo };
