How to compose read actions?

I have a read action with a small prepare that selects a few attributes and filters. I want to make a new read action that uses the same query as the previous read action, but also loads a calculation and a few relationships. How do I "compose" this with the old read action?

Solution:

You don't compose them together, you share a preparation between the two actions

You can build on read actions in code, eg.

Ash.Query.for_read(YourResource, :custom_read)
|> Ash.Query.load([more, loads, here])
|> Ash.read()

Ash.Query.for_read(YourResource, :custom_read)
|> Ash.Query.load([more, loads, here])
|> Ash.read()

but I don't think you can do it at the action level
