Correct way to refer to actor in custom validation?

Should we be directly reaching into changeset.context.private.actor? Seems janky.

Postgrex error when creating record with AshGeo type

I have a resource which contains an attribute defined as:

    attribute :point, AshGeo.Geometry do
      description "The underlying PostGIS geometry"
      allow_nil? false
      constraints geo_types: [Geo.PointZ]
      private? true
    end

    attribute :point, AshGeo.Geometry do
      description "The underlying PostGIS geometry"
      allow_nil? false
      constraints geo_types: [Geo.PointZ]
      private? true
    end

when I try and run a test which creates a record I get the following error:

** (Postgrex.QueryError) type `geometry` can not be handled by the types module Postgrex.DefaultTypes

** (Postgrex.QueryError) type `geometry` can not be handled by the types module Postgrex.DefaultTypes

I think this is to do with the Postgrex.Types.define added to the runtime.exs not being used in test?

How best to model partial updates of optional attributes?

The classic example is a "user settings" page, where if they only change their username but leave the password field blank, you want to not update the password, but instead ignore it. The best I can come up with is something like this:

update :update do
  change prevent_change(:password), where: [absent(:password)]
end

update :update do
  change prevent_change(:password), where: [absent(:password)]
end

Is there a better way to achieve this?

GraphQL: Disable filter generation for some read actions?

I am wiring up some AshAuthentication actions to a GraphQL API and I've noticed that it generates filter arguments for actions like signIn(email: String!, password: String!) which is nonsensical. I can see the derive_filter? boolean option for the whole resource, but is there a way to do it for a single query or mutation?
