JoinDifferences 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
```elixir...
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:
```

attribute :email, :ci_string, allow_nil?: false...How to determine if the current page is the last or first page in Keyset pagination
I may be missing this from the documentation, but is there a way to find out if the current "page" is the firsrt or the last?
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....How to make fields optional for graphql api?

many_to_many exception after updating Ash
