JoinMany_to_many on email destination
I'm try to create a many to may relationship between a workspace and a user, using user email instead of the user id. But when i try to create the a WorkspaceUser I get an error:
```elixir

Invalid association, not an ecto schema
I'm getting a strange compile error that I can't replicate locally, only in GitHub Actions, I'm on the latest version of everything, ash deps, elixir and erlang.

CRDT and Ash
First of all: Why use Ash? Because declarative programming and Elixir are awesome. Why CRDT? Because they are awesome too - anyone who's dealt with LiveViews losing their sockets knows what I mean.
I'm using Rustler to talk to a Yjs (the package is Rjs which is pronounced 'wires'). A NIF written in Rust accepts an Ash resource instance and creates a Yjs document from it. I am contemplating how to do this in a generic way, and it appears that, while I might be able to code an Ash extension for this, it won't work with Rust serde. I'm contemplating using Json instead since it works bidirectionally between Ash and Yrs. Are there any gotchas I should be aware of when serializing Ash structs to Json? Would at least parts of JsonApi be of help? I haven't thought a lot about references yet but I think they will be links instead of being embedded. Every resource will have its own Yrs document.
For now, this is just a fun experiment for learning CRDT and Rustler. Thanks!...
How to return custom errors in a after_transaction call?
Let's say I have a change with the following implementation:

Action argument shows up as JsonString in graphql schema
I have this argument referencing another resource
however this argument is not showing the inputs that are available, is there a specific way to configure this so the input shows up correct in the schema?...

many_to_many with non-default attribute not preloading...
So, I have a many to many relationship I'm strugling with. It must be something silly, but I just can't make it work.
I have a resource called
Game, which is actually for a table called assets, so in the join table one of the attributes is asset_id and not game_id.
The join table is called playlist_entries...Looking for an example of an attribute-based custom filter check I once saw in an error message.
I saw once it in an error message, but can't find it anywhere online. It would correspond to this passage in the documentation, for create actions:
...
Keep in mind that, for create actions, many expr/1 checks won’t make sense, and may return false when you wouldn’t expect. Expression (and other filter) policies apply to “a synthesized result” of applying the action, so related values won’t be available. For this reason, you may end up wanting to use other checks that are built for working against changesets, or only simple attribute-based filter checks. Custom checks may also be warranted here.

Hooking `manage_relationship`
Is there a way to specifically hook into
manage_relationship, e.g. for an extension? I'm looking to get notified any time a relationship is added or removed.Composing filter expressions
I'm trying to figure out how to reuse/compose (eg. apply a

I have a complex filter expression that looks like this:
