Hey there!
I'm trying out ash_sqlite on a toy project, and I'm encountering an issue which seems to boil down to querying a calculation defined as inline elixir code.
Here is the error (full stacktrace in the next post), followed by some relevant code. Happy to add more context if required....

I'm considering using
ash_geo, but noticed it doesn't use the same patterns extensions like ash_money for installing postgres extensions and types. I know it's not owned by the ash-project org, but wanted to see what people thing about giving it an overhaul to have a nicer installation experience and follow current extension patterns.How do cleanly do action accepts for resources with a lot of attributes without `:*`?
With
:* being deprecated in the future major version of Ash. Will you have to put all attributes in the accepts for the actions need to support all attributes?
The answer very well may be you just have to list all the attributes in the action. But wanted to check....Solution:
default_accept in the top level actions blockIs there a way to not sign in users automatically after they register ?
I'm having that behavior by default
Solution:
The first one I'd suggest is to just have a plug after the user is set from the session that redirects all unconfirmed users to a page that says "please confirm your account"

I've recently done a refactor on a test suite to allow all cases to run asynchronously. Unfortunately at some point I've started getting intermittent
:table_not_found errors thrown on the actions of an Ets backed resource. It's almost guaranteed to happen when the whole suite (200+ tests) runs asynchronously. Is this expected? Meaning Ash.DataLayer.Ets isn't ready/meant to be used with asynchronous tests or am I missing some proper setup?
For reference, these Ets backed resources serve as an in-memory cache to avoid hitting the DB constantly. The main use-case is to cache actor/account permissions to be used by policies....Trouble with relationships and form
