Hello everyone,  
after 2 days searching the web for a solution i get stuck.

I have a rails APP with a SOAP interface and a simply ruby client  
e.g  
I have a object CAR that has a name and 4 DOORS

CAR \<-1:N-\> DOOR

//structure looks something like this  
class car {  
id  
name  
}

class door{  
id  
car\_id  
}

now i want to transfer a instance of the object car over soap to the  
client.  
SOAP only supports , primary class types like string, int, float and  
so on…right ?

now i was thinking about to do it with yaml or marshal, or xml i tried  
it the last 2 days but it dint work

# on the rails app i did

config\_dump = SOAP::Marshal.dump(cars)

# i did the transfer as a sting over soap

#on client side id did  
cars\_array = SOAP::Marshal.load(cars\_marshal)

but now i have a stange SOAP::Mapping::Object on the client side, is  
there a way to get a normal ruby object in this case CAR-object that i  
can do for example

car.doors.each{|door|  
puts door  
}

thanks ahead

regard

Hi,

If there’s no need for interoperability, you should use Marshal.

Hello NaHi,  
thanks, for you answer.

I m using SOAP and WSDL right now,  
do u know it there is a trick, i dont want to define all the CLASSES  
on the client or in the WSDL API struct , is there a opotunity to  
(auto)generate a WSDL/CLASS config from the activerecords structur  
which is on the server ?

i think it would be also much easier to maintain afterwards if u do  
any extensions to on the server side…

thanks ahread
