Right way to update data schema
Author: bokolobCreated Feb 5, 2024Updated Feb 5, 2024
Hello. I do it in this way
if (!doc.content.trip_settings || doc.content.trip_settings.version < 2) {
let migration = Automerge.change(Automerge.clone(this.doc, { actorId: "0002" }), { time: 1 }, (doc) => {
doc.content.events = {};
doc.content.trip_settings = {
name: this.text_node(db_record.name),
version: 2,
};
});
let [new_doc, patch] = Automerge.applyChanges(this.doc, [migration]);
this.doc = new_doc;
}As you can see - all migrations are different, because they set different name, so I can't prepare a blob.
After this migration was written I have some glitches, which I can't debug (Not sure that it's because of migration). E.g. sometimes last version of document becomes empty. And sometimes applying that migration again can return data back.
Is my code correct? Don't I forget something?
