I am trying to iterate over a hash but it only displays '#' for my key.
I know this is not the case because it outputs the correct number of lines
based on how many keys I have. If it were trully '#' it would only print on=
e
line.

Here is the code that is producing the output...
  <% @payment.batch.each do|key,value| %>
    <li><%=3Dkey%> -> <%=3Dvalue%></li>
  <% end %>

here is my output ...

   - # -> 1
   - # -> 1



Here is the code that builds the hash...
Controller...
def add_invoice
    @payment =3D find_payment
    @invoice =3D Invoice.find(params[:id])
    @payment.add_invoice(@invoice)
  end
def find_payment
    session[:payment] ||=3D Payment.new
  end

and the class....
class Payment
  include Reloadable
  attr_reader :batch

  def initialize
    @batch =3D {}
  end

  def add_invoice(invoice)
    unless @batch[invoice]
      @batch[invoice] =3D 1
    end
  end
end


TIA,
Paul
