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

when I add import Ash.Expr above, I get

@\ ឵឵឵ : I believe ash_geo is by you? import AshGeo.Expr was suggested in docs for ash_geo but that fails to compile with error 
** (CompileError) lib/companies_reg_ex/resources/recruiters.ex:6: module AshGeo.Expr is not loaded and could not be found

    action :create_loc do
      argument :location, :geo_any

      change set_attribute(:location, arg(:location))
    end
    action :create_loc do
      argument :location, :geo_any

      change set_attribute(:location, arg(:location))
    end
Maybe it should be create not action 
    create :create_loc do
      argument :location, :geo_any

      change set_attribute(:location, arg(:location))
    end
    create :create_loc do
      argument :location, :geo_any

      change set_attribute(:location, arg(:location))
    end
action is for basic stuff that does not explicitly work with the resource, therefore change might not be possible there

docs for action say 
The :action type is a special type of action that can do essentially whatever you want.

I think this is more in the line of manual actions something that is not a typical create/update/delete

Hi @abeeshake456, thanks for the report. I've updated the readme to correctly reflect the new module naming and use create, as well as some updates for latest ash and ash_postgres. v0.1.3 will be up in a few minutes after CI.
