AttributeError: Assignment not allowed to composite field "task" in protocol message object
I don't know protocol-buffers but I took a look at the docs and it says:
You cannot assign a value to an embedded message field. Instead, assigning a value to any field within the child message implies setting the message field in the parent.
So I'm assuming this should work:
task = yacc.task()task.id = 1000task.msg = u"test"ptask = yacc.task_info() ptask.task.id = task.idptask.task.msg = task.msg
I'm new to protocol-buffers too and faced with the same problem. I've found this method helpful.
I think it should work:
task = yacc.task()task.id = 1000task.msg = u"test"ptask = yacc.task_info() ptask.task.MergeFrom(task)
