What is the __metadata__ field in new versions of Ash?
I just updated my Ash to the latest version 2.13.2.
After that, I noticed that a lot of my unit tests stopped working basically because I was comparing resources.
From what I can see, when I create the resource, the
__metadata__ field will be a empty map %{}, but when I fetch the same resource with a read action, it will contain a key called selected in that map with the list of fields that were selected.
Was this a new addition?
Is there some way to disable that in tests so I can compare resources maps instead of having to process then before doing my asserts?4 Replies
How old was your previous version?
i think I was in 2.10.something
In general, comparing instances of resources using == is not a good idea, unfortunately.
There is a utility in
Ash.Test called strip_metadata that you can use to clean lists/pages/instances of resources of their metadata for comparison
Ah, cool! Thanks, I will try that out
