I think configuring it in the notifier would be better

ah right, if you had an update action that doesn't touch the resource itself, but uses hooks to do related stuff, you still want to know about it. that makes sense

it seems like a sensible default to me, but it would definitely be a breaking change if anyone was relying on the old behaviour. i can't think of an example of when the current behaviour would be wanted though. for atomic operations (or any case where it can't be known if something happened or not) we should probably default to sending the notification

Possible to skip validation for an action? (or best practices for working with external credentials)

I got this to work 😄 My resource code:

    create :create do
      primary? true
      argument :run_external_validations, :boolean, default: true, private?: true

      validate {Vendor.CredentialValidation, []},
        only_when_valid?: true,
        before_action?: true,
        where: argument_equals(:run_external_validations, true)

    create :create do
      primary? true
      argument :run_external_validations, :boolean, default: true, private?: true

      validate {Vendor.CredentialValidation, []},
        only_when_valid?: true,
        before_action?: true,
        where: argument_equals(:run_external_validations, true)

My test factory code:

  defp insert_vendor_params!(params) do
    Vendor
    |> Changeset.new(params)
    |> Changeset.set_argument(:run_external_validations, false)
    |> Changeset.for_create(:create, authorize?: false)
    |> MyApp.Api.create!()
  end

  defp insert_vendor_params!(params) do
    Vendor
    |> Changeset.new(params)
    |> Changeset.set_argument(:run_external_validations, false)
    |> Changeset.for_create(:create, authorize?: false)
    |> MyApp.Api.create!()
  end

I can add one in my project and then contribute it back 👍

okay so I'm definitely using it very wrong

the docs say

Validations that should pass in order for this validation to apply. These validations failing will not invalidate the changes, but will instead result in this validation being ignored. Accepts a module, module and opts, or a 1 argument function that takes the changeset. Defaults to [] .

so its not "return a boolean to run", but I don't know what it is

I think I'm not understanding how to run the validation conditionally. I've tried:

create :create do
      argument :run_external_validations, :boolean, default: true, private?: true

      validate {Vendor.CredentialValidation, []},
        only_when_valid?: true,
        before_action?: true,
        where: &Ash.Changeset.get_argument(&1, :run_external_validations)

create :create do
      argument :run_external_validations, :boolean, default: true, private?: true

      validate {Vendor.CredentialValidation, []},
        only_when_valid?: true,
        before_action?: true,
        where: &Ash.Changeset.get_argument(&1, :run_external_validations)

but that seems to always skip it

I'll take a look at doing this shortly and mark resolved if I can get it all working 🙂

that would be doable, given I only do it a few places in factory methods I think

Yeah I thought later maybe I could add an argument to the action to decide whether or not to run the external validation, defaulting to true, set to false in tests

I have just seen that its possible to skip_global_validations? from inside an action (I'm guessing that would be validations from a validations block on the resource?) so there might be a way to skip validations from outside, hidden somewhere

Which type for Text?

I'm pretty sure using :string will define fields as type text, so not size limited like a varchar

Create a resource including a belongs_to id

In your Location resource:

actions do
  create :create do
    primary? true
    change manage_relationship(:level_id, :level, type: :append_and_remove)
    ...

actions do
  create :create do
    primary? true
    change manage_relationship(:level_id, :level, type: :append_and_remove)
    ...

this would allow the level_id attribute to be set when creating a Location, ensuring it's also a valid value etc.

Create a resource including a belongs_to id

in your create action definition, you would use manage_relationship to allow the setting of the level_id - let me grab an example
