help with ash_geo for using locations.

Resource definition looks like

defmodule CompaniesRegEx.Resources.Recruiters do
  use Ash.Resource, data_layer: AshPostgres.DataLayer
  import AshGeo.Postgis


actions do
    defaults [:create, :read, :update, :destroy]

    action :create_loc do
      argument :location, :geo_any

      change set_attribute(:location, arg(:location))
    end

    read :containing do
      argument :location, :geo_any do
        allow_nil? false
        constraints geo_types: :point
      end

      filter expr(^st_within(^arg(:location), location))
    end
end


  attributes do
    # Add an autogenerated UUID primary key called `:id`.
    uuid_primary_key :id
    attribute :location, :geometry
  end

end

defmodule CompaniesRegEx.Resources.Recruiters do
  use Ash.Resource, data_layer: AshPostgres.DataLayer
  import AshGeo.Postgis


actions do
    defaults [:create, :read, :update, :destroy]

    action :create_loc do
      argument :location, :geo_any

      change set_attribute(:location, arg(:location))
    end

    read :containing do
      argument :location, :geo_any do
        allow_nil? false
        constraints geo_types: :point
      end

      filter expr(^st_within(^arg(:location), location))
    end
end


  attributes do
    # Add an autogenerated UUID primary key called `:id`.
    uuid_primary_key :id
    attribute :location, :geometry
  end

end

The error seems to be

Compiling 2 files (.ex)

== Compilation error in file lib/companies_reg_ex/resources/recruiters.ex ==
** (CompileError) lib/companies_reg_ex/resources/recruiters.ex:34: undefined function change/1 (there is no such import)

when I add import Ash.Expr above, I get

implementing state_timeout in AshStateMachine

Just had a look at https://github.com/ash-project/ash_state_machine/blob/v0.1.4/test/ash_state_machine_test.exs Is there an option similar to :state_timeout from https://www.erlang.org/doc/man/gen_statem.html#type-timeout_event_type The use case is - if one state doesn't get a new transition within :state_timeout seconds, it doesn't keep waiting forever

guide for using Ash.Flow and multi step user flow with retries.

Hi Jack. Thanks for the good work you have put so far.
I was looking at Ash.Flow and the step DSL feels what i Might need. Here is the Use case in detail: A student submits his solution (let's call it submission) on a portal. The administrator / staff then assigns that to a teacher. The teacher evaluates the submission and submits back to the portal. Staff approves of the evaluation submitted by teacher. Student can then see the evaluated submission. At any time, staff can cancel the submission assigned to the teacher. Staff can then re-assign it to any other teacher. If any teacher does not evaluate the submission for 3 days, staff is notified. Teacher can refuse to evaluate the assigned submission. This Flow can span several days. 1. Is Ash.Flow a good use case for this? In short, i need steps that are more like a gen state machine. I could sketch a rough diagram if that helps.
