i have string with ObjectId .
var comments = new Schema({
user_id: { type: Schema.Types.ObjectId, ref: 'users',required: [true,'No user id found']},
post: { type: Schema.Types.ObjectId, ref: 'posts',required: [true,'No post id found']}....
export let commentsModel: mongoose.Model<any> = mongoose.model("comments", comments);
How i user it:
let comment = new commentsModel;
str = 'Here my ObjectId code' //
comment.user_id = str;
comment.post = str;
comment.save();
When I create a "comment" model and assign a string user_id value or post I have an error when saving. I make console.log(comment) all data is assigned to vars.
I try:
var str = '578df3efb618f5141202a196';
mongoose.mongo.BSONPure.ObjectID.fromHexString(str);//1
mongoose.mongo.Schema.ObjectId(str);//2
mongoose.Types.ObjectId(str);//3
- TypeError: Object function ObjectID(id) {
- TypeError: Cannot call method 'ObjectId' of undefined
- TypeError: Cannot read property 'ObjectId' of undefined
And of course I included the mongoose BEFORE ALL CALLS
import * as mongoose from 'mongoose';
nothing works.

You want to use the default export:
import mongoose from 'mongoose';
After that, mongoose.Types.ObjectId will work:
import mongoose from 'mongoose';
console.log( mongoose.Types.ObjectId('578df3efb618f5141202a196') );
EDIT: full example (tested with mongoose@4.5.5):
import mongoose from 'mongoose';
mongoose.connect('mongodb://localhost/test');
const Schema = mongoose.Schema;
var comments = new Schema({
user_id: { type: Schema.Types.ObjectId, ref: 'users',required: [true,'No user id found']},
post: { type: Schema.Types.ObjectId, ref: 'posts',required: [true,'No post id found']}
});
const commentsModel = mongoose.model("comments", comments);
let comment = new commentsModel;
let str = '578df3efb618f5141202a196';
comment.user_id = str;
comment.post = str;
comment.save().then(() => console.log('saved'))
.catch(e => console.log('Error', e));
Database shows this:
mb:test$ db.comments.find().pretty()
{
"_id" : ObjectId("578e5cbd5b080fbfb7bed3d0"),
"post" : ObjectId("578df3efb618f5141202a196"),
"user_id" : ObjectId("578df3efb618f5141202a196"),
"__v" : 0
}
use this
var mongoose = require('mongoose');
var str = '578df3efb618f5141202a196';
var mongoObjectId = mongoose.Types.ObjectId(str);
