JoinAsh Record without persitance to the database
How can you manually create a record, so I can use it in my code, but not persist it to the database?
Parameterized custom policy checks?
Is there a way to pass a parameter to a SimpleCheck implementation module? Across most resources in my app, several checks need to be performed. Many of these checks are invariable, and can be put into a SimpleCheck module, but but one checks is variable, depending on a case-by-case basis. I would like to define one SimpleCheck module that does all these checks, and pass a parameter to it to handle that one variable case. Otherwise, I have to define repetitive checks in each of the resource modu...
Possible to skip validation for an action? (or best practices for working with external credentials)
My app has a resource called
Vendor for interacting with external vendors, so we store user credentials for those vendors encrypted in the resource. I've now added a validation when creating vendors, that validates that the credentials are actually valid (by talking to the external API). This works great!
However, I have a test suite that generates lots of Vendor resources in the course of testing things, and 99% of them don't use valid credentials (nor should they!) so now all the tests are failing due to this new validation.
I can see a couple of options:...No Absinthe schemas generated for resource
I've been using AshGraphql just fine, having created several resources that work with it. Then today, I created a new resource, and no Absinthe schemas are created from it.
How to have a "virtual field" in a resource based from another resource?
I have a
Organization resource that has a many to many relationship with my User resource.
That relationship is defined by this field in the Organization resource:

Custom / virtual fields on read
Hi All,
I am creating an API based on an old system and can't modify the original, but I want to change the way the resources are read. More specifically I want to set a certain virtual field based on the value of an existing database field.
Normally this is something I would achieve with a virtual field and then modify the output in the view layer. But I understand the idiomatic way in Ash is to push as much as possible into the resource....

Can I expose a generic resource action via an Ash GraphQL mutation?

What happens when :prev page request is used but there is no previous page?
Need help understanding how keyset pagination works. Here are the steps I took.
1. 'search-change' handle_event does the initial search properly. The query output is saved in a variable called page.
2. When the 'prev'' button is clicked triggering 'prev-page' handler, (as expected) nothing happens.
3. When the "next" button is clicked triggering 'next-page' handler, nothing happens. I expected it to return the iintial search results again, or the set after that.

Expand Ash.Query.Operator built_in operators
Right now, ash comes with a bunch of built-in operator for queries (
is_nil, eq, in, less_than, etc).
These are great, but it is not enough in some cases. For example, let's say I want to create a similarity operator?
The obvious answer is that I can implement it myself using the Ash.Query.Operator.__using__/1 macro....Custom type don't show all possible filters in GraphQL Api

Bulk create form
I currently have a phoenix form to create an invite. The form is connected to the create action on the Invite resource. The only field is email.
I want to change the form to accept multiple email addresses--comma separated--and then create multiple invites. The create action currently generates a token and sends an email, so it's bit more complicated than a db insert.
I haven't used manual actions, the new bulk_create feature, or Ash.Flow yet. I'm not sure which is the best route....

Ash.Error as application's exception/error module
Hello.
In a previous project (which did not use Ash) we had a top-level Error module that had a
In a previous project (which did not use Ash) we had a top-level Error module that had a
defexception in it with all the typical error things, like codes, messages, and metadata. It also had some other functions to do things like, for example, report the error to various sinks (Logger and an APM platform). The idea was to replace returns like {:error, :some_error_code} or {:error, "some message"} with {:error, MyApp.Error.exception(...)} and let code that receives such errors decide it it wants to report, re-raise, etc etc.
With the existence of Ash.Error and all the helper code around it, I wonder if it makes sense to build an application's top-level error off of Ash.Error instead of something custom? Even if those errors might not have anything to do with Ash?
Is it the intention of Ash.Error to be used purely for errors coming from the framework, or is it a building block for user-defined errors?...implementing state_timeout in AshStateMachine

Few Ash.Flow questions
I've just started playing with Ash.Flow and I've got a few questions.
1) Is it possible to have a branch step with a condition like
expr(Money.positive(^arg(:amount))), I've tried and get a Spark DSL error.
2) Is there a neater way to get_by a resource (similar to how we do it for code_interface) than having to define a separate action? - or does this go against the ethos of Ash.Flow, currently it seems slightly disjointed, with one part of the API encouraging one way and providing nice helpers, but another part not being really integrated, I'm assuming this is just me wanting to use it wrong and carry over certain bad habits / not knowing the magic helpers that do exist...
3) Are there plans to have a flow be able to be invoked via a code_interface?...
