Francois, seesm there was a number of hickups with this code snippet. Try out this:
---------------------------------------------
import neo4j
from neo4j.util import Subreference
#Then re open it in other function and added some nodes and indexes
#open databse
graphdb = neo4j.GraphDatabase("database")
with graphdb.transaction:
#create or get root indexes
rootindex = graphdb.index("root_index", create=True)
#Categories******************************************************************
#get categories root nodes
categorynode = rootindex["Categories"]
#create or get categories root nodes
sectornode = Subreference.Node.SECTOR_ROOT(graphdb, label="Sectors", level=1)
try:
ls_message = ls_message + categorynode["label"] + ", "
except:
categorynode = graphdb.node(label="Categories", level=2)
rootindex["Categories"] = categorynode
graphdb.shutdown()
-----------------------------------------------
And you should get something like the attached image. Does that help?
