[Quickfix-developers] Issues trying to parse an outgoing logon message in ruby-based implementation of an initiator

[Al <bro...@gm...>]

Hi.

I'm having issues with a ruby implementation of an Initiator.  I'm
required to attach the password in tag 554 to be embedded into the FIX
login message for 35=A.  Using "password" in the cfg file does not
work.  (It’s in the FIx4.4 spec but not in the Fix4.2 spec, which is
what I’m supposed to use.)

So, I added some code in my toAdmin method  to embed the password into
the message.  For some reason, I get an “undefined method” error right
where I need to parse the message.  It seems that whatever is getting
passed through the method toAdmin into the message parameter isn’t
actually the type of object I’m expecting.  But my little debug line
suggests that it is.  (I tried to use Marshal to take a better peak
into message, but got a "no marshal_dump is defined for class
Quickfix::SessionID" error.)

   def toAdmin(sessionID, message)
     puts "toAdmin: #{message.to_s}\n"  # debug:  Displays “toAdmin:
FIX.4.2:GBR->LIME”

     beginString = Quickfix::BeginString.new
     msgType = Quickfix::MsgType.new
     message.getHeader().getField( beginString )  # Error: undefined
method `getHeader'
     message.getHeader().getField( msgType )

     if msgType.getValue() == "A"
       add_logon_field(message);
     end

   rescue Exception => e
    print "Error: #{$!}\n"
    print e.backtrace
   end


Output:
