Hey all, I'm having an odd issue where I'm getting an error stating that my model isn't a constructor.... did I miss something? I have my Schema Defined, and Model created:
const ModelSchema = new Schema({...});
module.exports = Model = mongoose.model('model', ModelSchmea);and I'm importing it into my route file and using it like this:
const Model = require('../path/to/model');
router.post('/', (req,res) => {
let newModel = req.body;
new Model(newModel).save().then(...)
});not sure where the issue is
I’m trying to remove an ObjectId from array but it’s not working:
User.findByIdAndUpdate(ctx.session.user._id, { $pull: { events: objectId } })
this is the user document:
objectid is done with:
const objectId = Types.ObjectId(ctx.query.eventId)
@benydc your syntax looks correct tested here you might need to provide more details, like the values of
ctx.session.user._id and objectid that you are passing in to update and maybe use mongoose.set('debug', true) to see what mongoose is actually sending in the query.
ctx.session.user._id it’s the User Object Id and objectId I create it with the Types.ObjectId(stringID)
maybe Types.ObjectId is not generate the correct ObjectId
I enabled mongoose debug
I don’t think my update is even called
is the
_id path in your user session schema a string or the default ObjectId?
it’s the default ObjectId
I used it elsewere and it works fine
in queries that work, do the objectId's look like the ones in this failing query?
ok, somehow is working now…..
I used
await User.findByIdAndUpdate(userId, { $pull: { events: objectId } })userId I pulled from the session
yeah, that makes sense. ObjectIds have to be 24 hex chars.
node -e "m=require('mongoose');x=m.Types.ObjectId('152838454774-L5EBhCIDshleBtixmyB4epdK6HvYoMRr');console.log(x)"throws:
Error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters
@cjrutherford the only way I could duplicate the error is by removing the module.exports line in the exported model. It should work :confused:
it's okay @lineus , I was missing an 'S'
module.export versus module.exports
cool
I have a json array and I want to create Schema Objects without using forEach, is that possible?
@benydc what do you mean by Schema Objects?
documents
ah, yeah you can pass an array of objects to
Model.create() and it will save them all for you.
does it return array of documents?
yup
hey I have a question about errors, I have a route that depends on error messages to communicate issues to the front end, but it isn't working at all in production.
does mongo/mongoose still send error messages when in production?
or are they different in some way?
