i am getting error after error as i don’t know how to build a collection???
dataEnteringNode = IN
assemblies=UnwrapElement(IN[0])
elements=UnwrapElement(IN[1])
for i in range(0,len(assemblies)):
elemlist=[]
elemlist.append(elements[i].Id)
assemblies[i].AddMemberIds(elemlist)
OUT = assemblies
</div>
Hey Peter,
Just to check, did you create your assemblies in the same script? From the API guide:
“The static Create() method of the AssemblyInstance class is used to create a new assembly instance in the project. The Create() method must be created inside a transaction and the transaction must be committed before performing any action on the newly created assembly instance.”
If it is a committed assembly, then maybe try the following:
Dimitar thannk you, that really helped a lot.
didn’t know that a collection is that easy to build…
tx peter
Technically the method doesn’t build a collection, but an IList (which is a .NET derivative, i.e. the Iron part in IronPython) that has identical properties to an ICollection. I found it easier to translate the python list into an IList than to an ICollection.
I’m still trying to wrap my head around all the different containers. I found some more info about the multitude of containers in .NET here:
