ash json api - update by other field

  json_api do
    type "tasks"

    routes do
      base "/tasks"
      get :read_by_task_id, route: "/:task_id"
      index :read
      post :create
      patch :update_by_task_id, route: "/:task_id"
    end
  end


 actions do
    default_accept :*
    defaults [:create, :read, :update, :destroy]

    read :read_by_task_id do
      get_by :task_id
    end

    read :read_by_rlhf_link do
      get_by :task_rlhf_link
    end

    update :update_by_task_id do
 <<< how to read it by task id first and then uodate? >>
    end
end

  json_api do
    type "tasks"

    routes do
      base "/tasks"
      get :read_by_task_id, route: "/:task_id"
      index :read
      post :create
      patch :update_by_task_id, route: "/:task_id"
    end
  end


 actions do
    default_accept :*
    defaults [:create, :read, :update, :destroy]

    read :read_by_task_id do
      get_by :task_id
    end

    read :read_by_rlhf_link do
      get_by :task_rlhf_link
    end

    update :update_by_task_id do
 <<< how to read it by task id first and then uodate? >>
    end
end

Here is what I want to do 1. read the task by task_id and update the params received in the json api for that task.

https://hexdocs.pm/ash_json_api/dsl-ashjsonapi-domain.html#json_api-routes-patch-read_action Use a different read action and then configure the route to have task_id in it

Here is the updated config, but that does not work, I am missing something.

# in json api block
     patch :update_by_task_id do
        route "/:task_id"
        read_action :read_by_task_id
      end


# in actions block 

 read :read_by_task_id do
      get_by :task_id
    end


  update :update_by_task_id do
      argument :task_id, :string do
        allow_nil? false
      end
    end

# in json api block
     patch :update_by_task_id do
        route "/:task_id"
        read_action :read_by_task_id
      end


# in actions block 

 read :read_by_task_id do
      get_by :task_id
    end


  update :update_by_task_id do
      argument :task_id, :string do
        allow_nil? false
      end
    end

Tasks.update_by_task_id("787878", %{task_rlhf_link: "rlhf link from json api "})
{:error,
 %Ash.Error.Invalid{
   errors: [
     %Ash.Error.Invalid.InvalidPrimaryKey{
       resource: AutoElixir.Tasker.Tasks,
       value: "787878",
       splode: Ash.Error,
       bread_crumbs: [],
       vars: [],
       path: [],
       stacktrace: #Splode.Stacktrace<>,
       class: :invalid
     }
   ]
 }}

Tasks.update_by_task_id("787878", %{task_rlhf_link: "rlhf link from json api "})
{:error,

Its different for AshJsonApi and the way you're calling it YOu don't need the argument on the update action AshJsonApi does

Resource
|> Ash.Query.for_read(:read_by_task_id, %{task_id: task_id})
|> Ash.bulk_update!(:update, %{...})

Resource
|> Ash.Query.for_read(:read_by_task_id, %{task_id: task_id})
|> Ash.bulk_update!(:update, %{...})

If you want a code interface that does that, you can just have the update action, and do define :update_by_task_id, get_by: [:task_id] IIRC
