All of the operations that we worked with in our soap service,
0:04
took fundamental types, strings, integers, that sort of thing,
0:08
what if the operation, not only returned its own internal complex types,
0:13
but actually took them as parameters, it's easy to work with them
0:16
when they come back from functions, they are already allocated
0:19
you just start treating them as objects in memory,
0:22
but if you have to allocate one to input it into this method for example, how do you do that?
0:26
You can't just call some kind of initializer on it because well, it's created a runtime,
0:31
what are you going to do, okay, so if we want to use this post object
0:35
back in this operation, now remember, this is not how ours works
0:40
but if this were the case, suds has an answer for this as well.
0:43
Okay, so what do we do, again, we create the client just like before,
0:47
but now instead of going to client.service we go to client.factory,
0:50
and it can create these objects so we say client.factory.CreatePost
0:55
and that does all the internal runtime stuff to allocate one of those
0:58
with basically none values for all of the properties,
1:01
and then we can just set the properties, creating posts from suds is fun,
1:04
it works in Python 2 or Python 3, and of course, it hasn't been seen yet,
1:08
it's brand new so ViewCount=0.
1:11
Now once we have this rich type, we can use it as parts of our parameters,
1:15
and our operation so client.service.CreatePost
1:19
and we are going to pass this rich object which will be serialized
1:22
into the Soap message just like the contract in this example.
