How to create a type that contains multiple namespaces

I'm trying to receive and generate messages that can have the following schema:

<ns1:data>
  <ns1:status-change/>
  <ns2:rpc-call/>
</ns1:data>

I then have:

class NS1ComplexModel(ComplexModel):
    __namespace__ = 'ns1'

class NS1Data(NS1ComplexModel):

    statusChange = NS1StatusChange
    rpcCall = NS2RPCCall

class NS1StatusChange(NS1ComplexModel):
    ...

But the outcome of this is that has the namespace of ns1 and not ns2.

I've been looking through resolve_namespace() and friends and I think I see what's causing it but I can't work out how to fix it or even work around it.

Solution

  • I think this is the same problem I'm having, and I solved it by defining

    class NS2RPCCall(NS2ComplexModel):
    class Attributes(NS2ComplexModel.Attributes):
        sub_ns = NS1ComplexModel.__namespace__

    This is from looking at spyne.protocol.xml.XmlDocument._get_members_etree and spyne.model.complex._gen_attrs.
