Hi,
I'm trying to fit the example from https://hexdocs.pm/ash/use-without-data-layers.html to call a web api,

How To: Atomic update with a where clause
I'm trying to implement this workflow:
Update a timestamp atomically on an existing record if the new timestamp is greater than the old one, and the old one hasn't changed while im updating it(optimistic update).
I know atomics just dropped on Ash core so wondering if this could be achieved with it.
This is the ash action in question:...
Adding Postgres NULLS LAST to an Ash prepare build sort
Hi! I spent a little bit trying to figure this out and wanted to share to make it more searchable.
Ash's sorts actually support NULLS FIRST and NULLS LAST as different options passed instead of the normal
:asc, :desc, etc:
```elixir...How To: Exclusion constraints in AshPostgres
Im setting up an exclusion constraint an a few time attributes. I dont see anywhere in the docs an affordance for exclusion constraints, only check constraints, so what I did is create the migration for the exclusion manually, but now im getting an ecto error asking me to add it to the changeset.

Just exploring some of the features of Ash as I am considering it for a new service I am implementing.
I went through the tutorial of setting up Ash authentication for a Phoenix app which worked just fine.
However I was unable to determine how I could extend it to implement 2FA / TOTP using say Nimble TOTP at https://github.com/dashbitco/nimble_totp ...
Using pgsodium with Ash
Wondering if there would be an Ash way to do column encryption with pgsodium? Currently I have just done them directly in the migrations files with
execute("SECURITY LABEL FOR pgsodium ON COLUMN table.column IS 'ENCRYPT WITH KEY COLUMN key_id NONCE nonce ASSOCIATED association_id'") for each column I want to get encrypted.
Would custom_statements in the Ash resource be the place to do this?...AshOban trigger `read_metadata` passed to action as argument?
Hello!
In the AshOban code, there is this documentation statement: https://github.com/ash-project/ash_oban/blob/main/lib/ash_oban.ex#L129
I can't see where metadata is passed to the update action. I presume it would be somewhere here: https://github.com/ash-project/ash_oban/blob/main/lib/transformers/define_schedulers.ex#L477-L492
What am I missing? Has this part of the feature been missed, or was it never the intention to grab the metadata back out of the Oban job table into Ash land again?...
Is there a good way to version string documents in ash?
I have a table of TODOs, with one column, a :description. A user can modify a TODO's description. I'd like to efficiently store the history of a document, so that the user can look through different past versions of the doc. Is there an easy/built-in way to do this in Ash?
set action argument in form
I have two resources: User and Account
I'm creating an AshFrom and use that to create an User. On submit, just before creating the User i need to create an account and pass it as argument to the action used in the

Unfortunately i can't manage to find a way to set the argument in the form before it calls the action...White labeling the Ash Admin
Hi all!
I'm looking at having the Ash Admin as part of the internal product of ours. Some questions:
- Is it possible to customize the UI components?
- Is it possible to show the admin pages below the tab interface of our website?
- Is it possible to have the root layout apply to the Ash Admin pages?...

Hi All,
This may be a strange question.
I am learning ASH and Phoenix which are excellent....
How to make 'actor' available in nested forms' action
I have
Ash.set_actor(current_user) in the mount function of a liveview that contains a nested form. The create/update actions of the main (posts) and sub form (comments), both of which includes change fn changeset, %{actor: actor}, the variable actor passes the proper user map for post , but nil for comment`. Also tried passing actor like below, but it didn't help either. Is there anything else I need to do to make it available in the nested forms' action as well?

I'm just digging into
ash_geo and attempting to implement a knn filter, as described here:

Unlike a distance search, the “nearest neighbour” search doesn’t include any measurement restricting how far away candidate geometries might be, features of any distance away will be accepted, as long as they are the nearest....

GraphQL API fails if custom type is not allowed via a field_policy
I noticed that if I ask my graphQL API to return a field that is forbidden, if the field is built-in, it will just return the field as
null, all the other fields normally (assuming they are not forbidden as-well) and an error in the errors list telling that this field is forbidden.
But, if I try the same with a custom type, then I just get the full result as null:

How to use fragments and not built-in predicates in Ash.Filter keyword list syntax?
The documentation only shows how to use the

Hi, I’m wrapping an external REST API with an Ash resource and therefor use
Ash.Resource.ManualRead. Reading the data is not a problem, but as the REST API is way less capable for filtering, I would like to run the returned data through the Ash filters I applied to the query. I mapped the returned data already to the Ash resource and now have an array of these resources. But how can I now apply the filters from the query? That’s what read!() normally would do, but calling that would lead to...
