Realm - Insert if realm object does not exist else update
I am using Realm in my react native project. Realm is encrypted. I am storing user object in it and there will be only one user so I have set the Id to be 1 always.
when the object exists, I just want to update it instead of create. How can i do it. as of now I can create it but once created I am unable to update it.
It errors with a message
Error: Attempting to create an object of type 'User' with an existing primary key value '1'.
my code:
//user schema functions
export const insertUser = user => new Promise ((resolve, reject) => {
var encryptedPin = cryptoEncryptTest(getGlobalPin());
Realm.open(
{path: 'retailApp.realm',
schema: [ userSchema],
schemaVersion: 0, //optional
encryptionKey: encryptedPin }
//databaseOptions
).then(realm => {
realm.write(() => {
realm.create(USER_SCHEMA, user);
resolve(user);
});
}).catch((error) => reject(error));
});
I read about copyToRealm and append but I am not sure how to use and which is the write way. I tried to delete it before inserting but I dont think that is the right way of doing it.
please suggest how to achieve this.
Thanks

You can update
var song = realm.objects('song')//replace with your object(USER_SCHEMA)
realm.write(() => {
realm.delete(song);
realm.create('song', currentSong, true);
})
