I have a absinthe object type like that:

defmodule ContentProxyGraphql.Schema.ObjectTypes.Content do
  use Absinthe.Schema.Notation
  use Absinthe.Relay.Schema, :modern

  import_types Absinthe.Type.Custom

  object :content do
    field :type_of, non_null(:string)
    field :name, non_null(:string)
    field :date_created, non_null(:datetime)
    field :date_modified, non_null(:datetime)
    field :identifier, non_null(:identifier)
    field :publisher, :publisher
  end

  object :identifier do
    field :type_of, non_null(:string)
    field :property_id,  non_null(:string)
    field :value, non_null(:string)
  end

  object :publisher do
    field :type_of, non_null(:string)
    field :name, non_null(:string)
  end

end

In my schema.ex, I have the query

query do


    field :contents, list_of(:content) do
      resolve &Resolvers.Resources.Content.list/3
    end

  end

Now I’m creating the mutation

mutation do 
  field :create_content, type: :content do
    arg :typeOf, non_null(:string)
    arg :name, non_null(:string)
    arg :dateCreated, non_null(:datetime)
    arg :dateModified, non_null(:datetime)

    resolve &Resolvers.Resources.Content.create/3
  end
end

In my mutation I intend to add arg :identifier and arg :publisher. According to absinthe documentation (Complex Arguments — absinthe v1.11.0) I have to create a input_object :indentifier and a input_object :publisher with their fields, which are the same of respective object :identifier and object :publisher.

Is there a way to reuse object fields inside input_object? I’m trying it to avoid code duplication, in other words, I would like to avoid

input_object :identifier do 
    field :type_of, non_null(:string)
    field :property_id,  non_null(:string)
    field :value, non_null(:string)
end
