I don't know if you can help but I wonder if you’ve tried doing a bulk
load on existing tables with a relation. I’ve tried but come up
against a problem . I used the bulkloader example.
This is my schema.
Member — Running club member
Race — a race event racename,date, distance
Runner — is child of Member and Race being the time for the race taken
by the member.
-- These are my models
from google.appengine.ext import webapp
from google.appengine.ext import db
class Member(db.Model):
memberid = db.StringProperty()
name = db.StringProperty()
category = db.StringProperty()
currentMember = db.StringProperty()
member = Member()
member.put()
class Race(db.Model):
raceid = db.StringProperty()
name = db.StringProperty()
date = db.StringProperty()
distance = db.StringProperty()
units = db.StringProperty()
race = Race()
race.put()
class Runner(db.Model):
racerunner = db.StringProperty()
raceid = db.StringProperty()
runnerid = db.StringProperty()
runnername = db.StringProperty()
race = db.ReferenceProperty(reference_class=Race)
member = db.ReferenceProperty(reference_class=Member)
time = db.StringProperty()
position = db.StringProperty()
category = db.StringProperty()
WAVA = db.StringProperty()
pace = db.StringProperty()
notes = db.StringProperty()
runner = Runner()
runner.put()
#This is my data to load
#Runner.csv

I tried to load Runner with this:
#myRunnerloader.py
from google.appengine.ext import bulkload
from google.appengine.api import datastore_types
from google.appengine.api import datastore_entities
from google.appengine.ext import search
class RunnerLoader(bulkload.Loader):
def __init__(self):
# Our 'Race' entity contains an id name string date distance and
units
bulkload.Loader.__init__(self, 'Runner',
[('racerunner', str),
('raceid', str),
('runnerid', str),
('runnername', str),
('time', str),
('position', str),
('category', str),
('WAVA', str),
('pace', str),
('notes', str),
])
def HandleEntity(self, entity):
runner = datastore_entities.Runner(racerunner)
runner.update(entity)
raceid = runner['raceid']
runnerid = runner['runnerid']
if raceid:
race = datastore.Query('Race',{'raceid': raceid}).Get(1)
if not race:
race = [datastore_entities.Race(raceid)]
datastore.Put(race[0])
runner['race'] = race[0].key()
if runnerid:
member = datastore.Query('Member',{'runnerid':
runnerid}).Get(1)
if not member:
member = [datastore_entities.Member(runnerid)]
datastore.Put(member[0])
['member'] = member[0].key()
return runner
if __name__ == '__main__':
bulkload.main(RunnerLoader())
#And this cmd command on XP
runnercd C:\Google_apps
python "C:\Program Files\Google\google_appengine\tools
\bulkload_client.py"
--filename C:\Google_apps\data\Runnerfull.csv
--kind Runner
--url http://127.0.0.1:8080/runnerload
And I get this error:

Any ideas?
