I set the User._id to bsonType: objectId
in the User scheme. But when I registered the user using this Realm.App.logIn (realm-sdks/js/latest/Realm.App.html#logIn). I did not get the customData
. But when I changed _id
to string type. I started getting the customData
.
Every document in the custom user data collection should have a field
that maps it to a specific application user. The field must be present
in every document that maps to a user and contain the user’s ID as a
string.
And my question is: Where can I change to check matching type from string
to objectId
? And if I cannot do it. Why the developers used string
type for matching? Because string representation for object id is not optimised solution. (mongodb - The only difference between an ObjectID and the string version is that it's smaller? - Stack Overflow)
