Hi, I’m using Absinthe with Dataloader and have a question.

Here’s some code that mimics the example from the tutorial very closely (found here), all the usual suspects:

defmodule MyApp.Schema do
  # ...
  object :post do
    field :title, :string
  end

  object :author do
    field :posts, list_of(:post) do
      arg(:limit, :integer)
      resolve(dataloader(MyApp.Blog))
    end
  end

  def context(ctx) do
    loader =
      Dataloader.new()
      |> Dataloader.add_source(MyApp.Blog, MyApp.Blog.data())

    Map.put(ctx, :loader, loader)
  end

  def plugins do
    [Absinthe.Middleware.Dataloader] ++ Absinthe.Plugin.defaults()
  end
end

And then MyApp.Blog:

defmodule MyApp.Blog do
  # ...
  def data() do
    Dataloader.Ecto.new(MyApp.Repo, query: &query/2)
  end

  def query(queryable, params) do
    # How can I get params[:limit] to be the :limit arg from the schema???
    queryable
    |> limit(params[:limit] || 20)
  end
end

My question is: how can I access the limit arg attached to the posts field on author from the Schema, such that I can use an Ecto limit query inside MyApp.Blog.query/2? I can see in the docs that you can pass params along to the query function by passing them along in the Dataloader.load call, but from what I can tell, that is called internally.

Is there a way to pass the limit arg through that doesn’t involve abandoning dataloader and falling back to the raw batch function?

Thanks for any help!
