I’m really new to RoR and my first task is to write SOAP web service.  
The problem is that I don’t understand how to send custom SOAPFault  
messages in case of the errors.

For example, I have FindCustomerById API signature:

api\_method :find\_customer\_by\_id,  
:expects =\> [{:customer\_id =\> :int}],  
:returns =\> [Customer]

And controller:

def find\_customer\_by\_id(customer\_id)  
Customer.find(customer\_id)  
end

The requirement from the vendor is that if such customer does not  
exist  
I send back to client SOAPFault message with faultcode =  
“error”, faultstring = “no such customer” and such detail:

incorrect\_request Custome with such customer\_id does not exists

I cant figure out how to construct such SOAPFault message and send it  
back. Please help me, with some example code if possible.

Hi,

I am actually having the same problem. Have you figured out how to  
construct a SOAPFault object using RoR? If so, would it possible to  
give me some clue?

Thanks,  
Yan
