What is the correct type to use for an ObjectId field across mongoose and GraphQL?

Question

Following this tutorial, I have a mongoose model: (I\'m using the term \"Account\" instead of \"Todo\", but it\'s the same thing)

const Account = mongoose.m         


        

Answer 1

So what I just found is that _id is of type ObjectID but seems to implicitly cast to String. So if you define your mongoose model id type to be String instead of mongoose.Schema.Types.ObjectId then it should work. Using your current code (from the compose.com tutorial) that copies _id to id, the result will be that, in Mongo (after saving), the _id will be of type ObjectID and your model id will be of type string.

In other words, instead of this

const Account = mongoose.model('Account', new mongoose.Schema({
  id: mongoose.Schema.Types.ObjectId,
  name: String
}));

Do this

const Account = mongoose.model('Account', new mongoose.Schema({
  id: String,
  name: String
}));
