find by _id with Mongoose
Because this query finds the doc in the shell:
db.getCollection('stories').find({_id:'572f16439c0d3ffe0bc084a4'})
That means that the type of _id
in the document is actually a string, not an ObjectId
like Mongoose is expecting.
To find that doc using Mongoose, you'd have to define _id
in the schema for Story
as:
_id: { type: String }
If your Mongo schema is configured to use Object Id, you query in nodeJS using
models.Foo.findById(id)
where Foo is your model and id is your id. here's a working example
router.get('/:id', function(req, res, next) {
var id = req.params.id
models.Foo.findById(id)
.lean().exec(function (err, results) {
if (err) return console.error(err)
try {
console.log(results)
} catch (error) {
console.log("errror getting results")
console.log(error)
}
})
})
In Mongo DB your query would be
{_id:ObjectId('5c09fb04ff03a672a26fb23a')}
One solution is to use mongoose.ObjectId()
const Model = require('./model')
const mongoose = require('mongoose')
Model.find({ id: mongoose.ObjectId(userID) })
It works, but it is weird because we are using id instead of _id
