Step 1: update Ash Step 2: mass rename Api to Domain Step 3: Ash.Query.expr -> Ash.Expr.expr Also change ref interpolation Step 4: remove all warnings Step 5: remove registries from tests Step 6: fix filter Step 7: private? -> !public? Step 8: Ash.Calculation -> Ash.Resource.Calculation Step 9: use depend_on_resources/1 -> resources/1 Step 10: add Domain to all resources Step 11: use Ash module for all actions Step 12: add public? true all around Step 13: remove verbose? from options passed during Domain calls Step 14: add simple_sat Step 15: Ash.ErrorKind is no more, so remove code from errors Step 16: sprinkle default_accept :* around tests Step 17: replace Ash.Changeset.new/2 with Ash.Changeset.for_* Step 18: calculation fixups - Context is now a struct and arguments go under the arguments key - Function based calculations receive a list of records - Add a select to query-based loads - select -> load Step 19: pass the correct name to pass the policy in tests Step 20: Ash.Query.new/2 is no more Step 21: add AshGraphql.Resource.embedded? utility function Use that instead of Ash.Type.embedded_type?(resource_or_type) since resources are not types anymore Step 22: handle struct + instance_of: Resource in unions Resources are not type anymore so they need to be passed this way in unions Step 23: ensure we only check GraphQL actions for pagination All reads are now paginated by default, so this triggered a compilation error Step 24: swap arguments for sort on calculations Step 25: remove unused debug? option

# Using Subscriptions
|
|
|
|
The AshGraphql DSL does not currently support subscriptions. However, you can do this with Absinthe direclty, and use `AshGraphql.Subscription.query_for_subscription/3`. Here is an example of how you could do this for a subscription for a single record. This example could be extended to support lists of records as well.
|
|
|
|
```elixir
|
|
# in your absinthe schema file
|
|
subscription do
|
|
field :field, :type_name do
|
|
config(fn
|
|
_args, %{context: %{current_user: %{id: user_id}}} ->
|
|
{:ok, topic: user_id, context_id: "user/#{user_id}"}
|
|
|
|
_args, _context ->
|
|
{:error, :unauthorized}
|
|
end)
|
|
|
|
resolve(fn args, _, resolution ->
|
|
# loads all the data you need
|
|
AshGraphql.Subscription.query_for_subscription(
|
|
YourResource,
|
|
YourDomain,
|
|
resolution
|
|
)
|
|
|> Ash.Query.filter(id == ^args.id)
|
|
|> Ash.read(actor: resolution.context.current_user)
|
|
end)
|
|
end
|
|
end
|
|
```
