Modifying the argument clashes with AshCloak changing the argument's type
Hello! I have a resource
Platform with an attribute called credentials I want to have encrypted. This attribute is a union of embedded resources (representing credentials for different platforms).
I have a change that sets the type attribute on the credentials union changeset to the same value as the platform.type is set - to avoid having to pass the same value twice and ensure the credentials type matches the platform type.
After adding the AshCloak encryption, it replaces my argument :credentials, :map with its own argument typed as a union.This causes my change to fail, because:...How to set user as actor after login?
When logging in with the
sign_in_with_password action provided by AshAuthentication, I would like to set the loaded user as an actor so that it is possible to apply policies and load relationships already at login.Changing attributes in action

You can't use expressions in that context
How to write a policy to ensure the user belongs to the tenant through a membership relation?
I have read many examples on multitenancy implementation with Ash, but most of these examples assume that the user belongs to one tenant.
In my case, a user can belong to one or more tenants and can switch from one to another using a select list.
We therefore have three resources, Organization, User, and Membership, to make the connection. Our application mainly uses a JSON API where we pass an authentication token in each request, as well as a custom X-Org-Id header with the current tenant ID the user selected....
Solution:
You should be able to create a SimpleCheck that can confirm that the actor has a membership for the tenant though: https://hexdocs.pm/ash/Ash.Policy.SimpleCheck.html#content

Loading data from an external API for a calculation
Hello! I have a resource that I would like to enhance in certain reads with a calculation that needs to be based off data from an external API.
I'm mindful of not wanting to make the API request from within a transaction if possible.
I thought of adding a preparation to the read action that will fetch the API data and put it into the context, which the calculation can use.

Flattening Polymorphic Relationships in Ash GraphQL
Hey folks 👋
I’m working with polymorphic relationships in Ash and followed the guide here: https://hexdocs.pm/ash/polymorphic-relationships.html. I tried exposing it through the GraphQL API, and I’m a bit unsure if there’s a way to shape the schema the way I want.
Right now, when I query

Hi everyone! So I have been playing with the
mix phx.gen.auth in my Inertia setup and was wondering:
a) Am I losing anything if I don't use Ash Auth yet if I already has my auth configured from the phx.gen.auth since I can just pass the right scope for the actors when using Ash? I am migrating my models to Ash resources now but I need to understand how the ash auth works in tandem with the ash resources as a whole.
b) For the auth vs phoenix auth, I assume phoenix auth is just the UI/liveview + routes scope on top of the ash auth? I can still build my own routes with Inertia rendering and use the auth module to trigger the auth internally right?...Solution:
you can just use your generated auth, Ash doesn't really care to much about what you pass in as an actor, your policies just need to know how to work with it. I've used ash with our own custom auth before ash_authentication was a thing, worked without a hitch.
ash_authentication_live_session dups
After implementing
Ash.Scope, it occurred to me that I'm sort of duplicating assignments with current_user as it's also set via ash_authentication_live_session. Is this generally just how folks do things for convenient access in the view or should I be deduplicating somehow? I feel like I shouldn't care but it bothers me on some level lol. Thanks!Cross schema many_to_many
Hi, I have two resources let's say A and B, A is using :context multitenancy, B is in the public schema.
I want to have a many_to_many relationship between A and B, using a AB resource that also is using :context multitenancy.
The issue is that when I try to load the B records directly from A (MyApp.get_a(a_id, tenant: tenant, load: [:bs]), The query generated tries to join with an AB table from the public schema, which does not exist as it is a multitenant resource. Did I miss something or is it a bug ? Loading through the join resource does work though (MyApp.get_a(a_id, tenant: tenant, load: [abs: [:b]])...
TypedStruct with array and default

AshJsonApi: Can a domain support routes for different endpoints/routers?
I'm looking into exposing some API routes only for my internal network, which won't be publicly accessible. Is it possible to configure routes to be exposed for one or more endpoints/routers? i.e. Some routes are public only, some private only, others are both.

The policies:

Solution:
yeah, in this context, the policies don't guarantee an actor. you could wrap this in before_action and than you'd know that if you reach the hook that there is an actor beccause of the policy, or you could just handle the actor being nil
