问题 I have two Realm files configured in my app. I want to store my Log model to a separate file from the rest of my models.

由 亡梦爱人 提交于 2019-12-06 06:39:23
问题 Can I change old primary key with new primary key in realm migration script? 回答1: Yes, it is possible. RealmObjectSchema objectSchema = schema.get("MyObject"); objectSchema.addField("newId", long.class) .transform(new RealmObjectSchema.Function() { @Override public void apply(DynamicRealmObject obj) { obj.setLong("newId", getNewId(obj)); } }) .removeField("id") .renameField("newId", "id") .addPrimaryKey("id"); However, you can't directly create the field as objectSchema.addField("newId", long

I'm new to realm and I'm having a lot of trouble getting a nested object to save.

Realm.open vs new Realm

由 ε祈祈猫儿з 提交于 2019-12-06 06:03:02

Looks like Realm.open is just a callback to make sure the syncronisation is done, so only needed for synced Realms? So far this is what I found: Realm.open: According to the doc reference Realm
