transfer (own)ruby object over SOAP

Philipp

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
Philipp

Hi,

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

Above should work. Please make sure you define user defined classes
(Car and Door) on the client side. Marshal requires it, too.

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

Philipp
