Refresh Parent Record data in UI after server side process

[Kyle]

Hi,

I have a parent child relationship (one to many).
Updates on the child record trigger a hook that updates values on both the child record and its parent record.
The child record data is updated in the UI but the parent data is not.
How can I refresh a parent record from the context of a child record?

I have tried

this.model.fetch();
this.model.trigger('update-all');

but this does not appear to work when done from the child context.

Is it possible to get each view/entity displayed on the screen and interact with them from another?

The problem was solved by doing the server side processing in a repository instead of using a hook. The data sent back after a using a repository had the latest values. The hook sent back old values.

Thanks for providing the solution !
