Chris,
now that Tobias is on site again, I got the code to work, it looks
like this now:
from __future__ import with_statement
import neo4j
graphdb = neo4j.GraphDatabase("neodb/test")
with graphdb.transaction:
addIdx = graphdb.index("address",create=True)
n = graphdb.node(color="Red", widht=16, height=32)
addIdx[n['color']] = n
graphdb.shutdown()
graphdb = neo4j.GraphDatabase("neodb/test")
with graphdb.transaction:
addIdx = graphdb.index("address",create=True)
Two points:
1. Indexes are created lazily, so unless you actually add something to
it it will not be created, thus not being available on the next
opening of the db.
2. addIdx = graphdb.index("address",create=True) is broken, so
omitting the create=True breaks things. Always use it, will be
rectified upon overhaul of the python bindings.
Does this help?
Cheers,
