How to: Conditional validation with built-ins
Im trying to validate an embedded field "payment_method" when a certain param/attribute has a specific value. I've tried to do this:

accept [:collection_method, :billing_cycle_anchor, :customer, :payment_method]
validate present([:collection_method, :customer])...
AshCsv - duplication on `upsert?: true`
I might be doing something wrong but when using AshCsv with

Calculations in AshJsonApi?
Just want to make sure I'm not missing anything obvious - is it possible to include a calculation in a JsonApi request? Including one in the

Prefixed base62 UUIDv7 primary key implementation with Ash
Hi all,
I'm trying to implement a UUIDv7 based primary key for all our Ash resources (and relationships), storing that as UUID type column on PostgreSQL and presenting that outside as a prefixed base62 string (
0188aadc-f449-7818-8862-5eff12733f64 will be shown as acct_02tRrww6GFm4urcMhyQpAS), like what is described here for Ecto (https://danschultzer.com/posts/prefixed-base62-uuidv7-object-ids-with-ecto).
I'll be happy to contribute with the result of this as a code sample or better as an elixir package as soon as I get it all working properly.
...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....Need a feature for customizing error message.
i.e. in string type, match constraint will return error message "must match the pattern %{regex}".
But, showing regex in user interface is not a good experience for users.
I need to customize error messages....
Differences between UUID primary keys in Ecto vs Ash
As far as I can tell, the Ash Resource special attribute

Howdy there. I've been trying the tutorials from the Ash website (both "Get Started" and "Get Started with Ash and Phoenix"). As I was going through, I couldn't help but wonder, "is there a way to do this without Phoenix's Ecto?"
In other words, if I'm planning on using Ash for all the domain logic, and Ash is going to use Ecto, can I initialize Pheonix without ecto and still get Ash to work right (since I'll be using Ecto with it)?

Check a policy manually
Is there a way in Ash to check a policy manually?
I want to check if a particular actor has the ability to update a specific resource. I wasn't able to find how to do that.
My use case is I'm creating a resource by passing in a Google Cloud storage signed url and I need to check if the path in the signed url is valid. Right now I have this:...

Policy checks on related resources
I have been looking for quite some time so this may be a noob ish question. I have a couple answers potentially but I'd like to know kind of the standard way to write a policy for a resource where the relationship to that resource is how I would authorize the actor.
For example
Let's say I have a GroupRequest resource which represents a users request to join a group (contains a group_id and user_id)
I also have a Group that has a group_admin relationship which belongs to a user....
