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
uuid_primary_key unwraps into:
```elixir
attribute :id, :uuid do
writeable? false
default &Ash.UUID.generate/0...Starting a Phoenix/Ash project with minimal cruft
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:...
How to insert a record with its nested children?
First, I'd love to thank everyone and especially Zash for the awesome work done in Ash
I have a few resources with some relationships between them, for brevity I'll only copy the relevant parts

Ash dropping FilterCheck if there's `authorize_if always()`
Hi, I've got a resource that in it's action has:
...
authorize_if MyApp.FilterByActorId
authorize_if always()
authorize_if MyApp.FilterByActorId
authorize_if always()
How do relationships with composite keys work?
I found this mention of composite keys in the docs:
```elixir
has_many :composite_key_posts, MyApp.CompositeKeyPost do
destination_attribute :author_id
end...
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....
Using manage_relationship to delete a related record
I have an action that accepts the ID of a related record. It should delete that record. However, when I tried using the
type: :remove option, Ash responds with Invalid value provided for notes: changes would create a new related record. Is this the right approach? Or should I manually delete the record?Confused about `one_of` vs `attribute_equals`
Still messing around and encountered a confusing behavior with validations. I have a
:verify action on a resource, which I only want to run on resources which have :role set to :unverified The below works as expected (produces valid/invalid changesets as expected):
```
update :verify do #custom action to verify an unverified user
validate attribute_equals(:role, :unverified) #only verify unverified users
change set_attribute(:role, :verified)...Calculatated fields and AshGraphQL
How can I query calculated fields in when graphql . the fields are virtual they don't exist as attributes. ?
Bypass not applying - had to pass actor again in load
Hi! I fought with this for an embarrassingly long time so I'm just gonna stick it here for SEO posterity.
I thought my superuser/staff bypass was inexplicably failing – it's at the top, what's the deal??? – but it turns out the policy system just wasn't seeing my actor at all where I assumed it was. I had to pass the actor in again on the
load! call.
not sure if there's a better way to do this type of thing but this is what's working now:...AshJsonApi + Managed Relationships
Are there any examples of AshJsonApi, the docs seem outdated. Im trying to get managed relationships to work through a 'parent' resource.
Can You Add Additional Attributes to ash_authentication_phoenix?
I went through the tutorial for and have password/email auth working. I'd like to add a
role attribute to my user resource so I did the below:

attributes do

attribute :email, :ci_string, allow_nil?: false...How to determine if the current page is the last or first page in Keyset pagination

Full debug SQL
Hi, during development, the sql statement is printed out by the
AshPostgres.DataLayer.run_aggregate_query/3, at: lib/data_layer.ex:738
A long enough sql would be truncated. How do I get the full sql without truncation?
Thanks!...Setting defaults for a form input that is an argument and not an attribute?
I have an update action that takes an argument. In the form for this action, I need to set the default value for the form input. The default value is dependent on the current state of the resource being updated.
I explored using the
default option for an action argument; however, It accepts a zero-argument function, so there's no way to get the resource being updated.
I explored using the prepare_params option for AshPhoenix.Form.for_update but I couldn't find any examples. It's arrity 2 and receives the params but is only called when the form is validated or submitted....
