Hi, we’ve recently encountered a problem with Ash in our project (we’re using version 2.21.15). Basically, we have the following resources in our system:
MyApp.Product which has the following relationship with MyApp.ProductVariant resource
has_many :active_product_variants, MyApp.ProductVariant do
filter is_active: [eq: true]
sort :order_weight
end
And in MyApp.ProductVariant we have a manual relationship called with StripeProudct (it is a product variant, but it’s a stripe resource that we access via stripe API) in this way:
has_one :stripe_product, MyApp.Stripe.Product do
api MyApp.Stripe
allow_nil? true
destination_attribute :id
validate_destination_attribute? false
manual __MODULE__.Relationships.StripeProduct
end
defmodule Relationships.StripeProduct do
@moduledoc false
use Ash.Resource.ManualRelationship
@impl true
def load(records, _opts, context) do
stripe_product_ids =
records
|> Enum.map(& &1.stripe_product_id)
|> Enum.uniq()
with {:ok, products} <-
MyApp.Stripe.Product
|> Ash.Query.for_read(:get_many, %{ids: stripe_product_ids}, actor: context.actor)
|> MyApp.Stripe.read() do
{:ok,
Map.new(products, fn %MyApp.Stripe.Product{id: "retail_" <> id} = product ->
{id, product}
end)}
end
end
end
In our app, we have the following piece of code that loads product variants for a list of products:
MyApp.load(products, [active_product_variants: :stripe_product],
actor: actor,
lazy?: true
)
And that’s where the fun begins… For some reason, context.actor in Relationships.StripeProduct.load/3 is always equal to nil despite having a proper value when executing MyApp.load/3, which causes Ash.Error.Forbidden every time
What’s more interesting when I delete lazy?: true like this:
MyApp.load(products, [active_product_variants: :stripe_product],
actor: actor
)
Everything is working fine.
Do you have any ideas about what’s happening?
