Cannot create vertex proxy with rexster

[KennethAdamMiller]

The following code:

import bulbs from bulbs.model import Node, Relationship from bulbs.rexster import Graph from bulbs.config import Config class Read(Relationship): count=0 g.add_proxy("Reads", Read)

Gives the following error: Traceback (most recent call last): File "", line 1, in File "/opt/local/Library/Frameworks/Python.framework/Versions/3 .2/lib/python3.2/site-packages/bulbs/base/graph.py", line 104, in add_proxy

You need to add the label definition to the top your Relationship model.

Oh sorry, yeah I actually figured that out, it just took me forever since I had had the element_type name set in the Relationship model. So, this is not an issue anymore.

Resolved.
