How to combine entities's history?

[toadfanszz]

Thank you for the awesome lib!

I'm implement a database system. And my question is about entities-history. Given the code:

Here is the store.

// Sheet has many rows, and I want to manage row history via sheet.
const sheetsStore = createStore(
    { name: "sheet" },
    withEntities<{id: string, rowIds: string[]}>(),
    withRowsEntities<{id: string, data: string}>()
  )

export const sheetsStateHistory = entitiesStateHistory(sheetsStore)
export const rowsStateHistory = entitiesStateHistory(sheetsStore, { entitiesRef: rowsEntitiesRef })

1.

// add row entity and update sheet entity in one transaction
sheetsStore.update(
  updateEntities('sheet1', {rowIds: ["row1"]}),
  addEntities({id: 'row1', data: 'first'}, { ref: rowsEntitiesRef })
)

// rollback the transaction, but row entity is still exist.
sheetsStateHistory.undo("sheet1")

Is there something like sheetsStateHistory.undo("sheet1", { entitiesRefs: [rowsEntitiesRef] })?

2.

sheetsStore.update(
  updateEntities('row1', {data: 'second'}),
)

// Is there a way to undo the above transaction via sheetId?
sheetsStateHistory.undo("sheet1")

Thanks in advance.

1. since you have two entity state histories you need to undo both of them independently:

sheetsStateHistory.undo("sheet1");
rowsStateHistory.undo("row1");

2. There's no way to do such a thing by entityStateHistory. But I guess you can do next:

sheetsStore.update(
  updateEntities('row1', {data: 'second'}),
)

const sheetRows = sheetStore.query(getEntity("sheet1")).rowIds;

if (sheetRows.includes("row1")) {
  rowsStateHistory.undo("row1");
}
