Nested transactions with step arguments buggy?

Support
1

Hi,

I’ve got transactions that call other transactions/operations. If I try to pass them step arguments they fail with the following error:

ArgumentError:
       wrong number of arguments (given 2, expected 0..1)
     # ./lib/dry/transaction/instance_methods.rb:25:in `call'

I’ve got a spec running (in spec/integration/passing_step_arguments_spec.rb) that shows the behaviour:

context "with nested transactions" do
    let(:transaction) {
      Class.new do
        include Dry::Transaction(container: Test::Container)

        step :root, with: :nested
      end.new
    }

    before do
      module Test
        nested_transaction = Class.new do
          include Dry::Transaction

          step :process

          def process(input, *args)
            Success input
          end
        end.new

        Container = {
            nested: nested_transaction,
        }
      end
    end

    context "arguments provided" do
      let(:step_options) { { root: ["doe.com"] } }

      it "passes the arguments and calls the operations successfully" do
        expect(call_transaction).to be_a Dry::Monads::Result::Success
      end
    end

    context "arguments not provided" do
      let(:step_options) { {} }

      it "calls the operation successfully" do
        expect(call_transaction).to be_a Dry::Monads::Result::Success
      end
    end
end

The spec with step arguments fails, the other one succeeds.
Is there something wrong with my approach or is this a bug in dry-transaction?

Thanks!

Hmm, this definitely seems like a bug! Would you mind filing an issue with this same test case?

Thanks. I’ve filed a issue here: https://github.com/dry-rb/dry-transaction/issues/124
