UnicodeEncodeError: bulbs and neo4j create Model

Question

I'm getting Unicode errors while trying to add data to Neo4J via Bulbs when the data contains non-ascii data.

the following code fails:

from bulbs.model import Node
from bulbs.property import String
from bulbs.neo4jserver import Graph

class User(Node):
    element_type="user"
    name = String(nullable=False)

g = Graph()
g.add_proxy("users", User)

user_data = {u'name': u'Aname M\xf6ller'}

g.users.create(**user_data)

with a UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 7: ordinal not in range(128)

The error is occurring in the bulbs.utils.u function, via codecs.unicode_escape_decode().

Some hopefully relevant info:

$>python -V
'2.7.3'

>>>type(user_data['name'])
type('unicode')

>>>import bulbs
>>>bulbs.__version__
'0.3'

The Neo4J docs state that all String objects are saved as unicode, so why is my unicode data not being accepted? I hope I am just missing something silly.

Yes, this was a bug. It's fixed in Bulbs 0.3.23:
