Actually I did. It took some messing about, but I post my solution
below so maybe it will help you:
Let us know how you solve it, and good luck.
class CainIncident:
name = db.StringProperty()
created = db.DateTimeProperty(auto_now_add=True)
class CainLoader(bulkloader.Loader):
elements = [
('name', str),
]
def __init__(self):
bulkloader.Loader.__init__(self, 'CainIncident',
self.elements)
def get_data(self):
'''returns an array of hashes like { 'name': 'Some Name'}'''
return [
{ 'name': 'Some Name'},
{ 'name': 'Some Other Name'},
]
def generate_records(self, filename):
data = self.get_data()
for record in data:
yield [
record['name'],
]
loaders = [CainLoader]
