Implementing token inactivity timeout with automatic expiry extend

For posterity, the token record is now provided by the plug helper (https://github.com/team-alembic/ash_authentication/pull/426/commits/2d6e563c1bc4b02a160bc2b374e61d500739b5d6), and I was able to implement session inactivity timeout in my application outside of ash_auth. Now that's done, I could possibly extract it (time allowing) and implement it in ash_auth as a new feature. Perhaps as an option on the tokens do block

Implementing token inactivity timeout with automatic expiry extend

I like the sound of that! Using extensions I have had to dig into the source, and this would help a lot.

Implementing token inactivity timeout with automatic expiry extend

Interesting thought, so extensions would never add actions, and users would need to add them in. However the extension could provide preparations / helpers to make this easy.

Yes that seems reasonable to me, thanks 🙂

Implementing token inactivity timeout with automatic expiry extend

That's a good point, as a work-around I could potentially set a very long token_lifetime and manage expiry myself outside ash_auth.

How can I do a 'like' query or similarity search?

(this assumes you're using ash_postgres as your datalayer)

How can I do a 'like' query or similarity search?

You could use an expression for this:

App.EmailHandler.User
|> Ash.Query.filter(
  expr(
    ilike(email, "%" <> ^search_slug <> "%") ||
      ilike(name, "%" <> ^search_slug <> "%")
  )
)

App.EmailHandler.User
|> Ash.Query.filter(
  expr(
    ilike(email, "%" <> ^search_slug <> "%") ||
      ilike(name, "%" <> ^search_slug <> "%")
  )
)

Ok good to know, and that there's a workaround 😀

Nested aggregates and calculations

OK this is brilliant, thank you! It gives me confidence that I can continue to build up calculations and aggregates and they will be composable.

Nested aggregates and calculations

Thanks, good to know it should work. I have submitted a PR that reproduces the issue here: https://github.com/ash-project/ash_postgres/pull/164

Expected at most one result but got ...

@richaard0 you can also do the following, which will define the filter on the read action for you, and return a single record instead of a list:

code_interface do
  ...
  define :get, action: :read, get_by: [:id]
end

code_interface do
  ...
  define :get, action: :read, get_by: [:id]
end

Metaprogramming with expressions

Found it 😀 – I had to use ref like this: Ash.Query.filter(ref(:id) == ^id)

Run an create/update action without persisting the data

There are also generic actions available that don't persist. https://www.ash-hq.org/docs/guides/ash/latest/topics/actions#generic-actions

Can't get policies to work with AshGraphql

You can create a new read action that gets the current actor from session. Here is what I have on my actor resource:

read :current_actor do
  get? true
  manual Ht.Actor.Actions.CurrentActorRead
end

read :current_actor do
  get? true
  manual Ht.Actor.Actions.CurrentActorRead
end

defmodule Ht.Actor.Actions.CurrentActorRead do
  use Ash.Resource.ManualRead

  @impl true
  def read(_, _, _, %{actor: actor}) when not is_nil(actor) do
    {:ok, [actor]}
  end

  def read(_, _, _, _), do: {:ok, []}
end

defmodule Ht.Actor.Actions.CurrentActorRead do
  use Ash.Resource.ManualRead

  @impl true
  def read(_, _, _, %{actor: actor}) when not is_nil(actor) do
    {:ok, [actor]}
  end

  def read(_, _, _, _), do: {:ok, []}
end

Then in your graphql definition:

mutations do
  update :update do
    identity false
    read_action :current_actor
  end

  ...

mutations do
  update :update do
    identity false
    read_action :current_actor
  end

  ...

Does your actor have a relationship to the customer already?

Can't get policies to work with AshGraphql

Great! Glad you got it working. Also I just ran one of my unit tests that uses GQL, and when I turn on the policy logging it does log all the policy logs with breakdown, so i'm not sure why that doesn't work for you.

From memory, ash_graphql does need to have permission to also :read the thing it's updating, could that be it?
