Bigtable. I don't have any other models but the standard auth ones and the
builtin wiki ones and I'm using this code (just the one stated in the book):
def import_and_sync():
form = FORM(INPUT(_type='file', _name='data'), INPUT(_type='submit'))
if form.process().accepted:
db.import_from_csv_file(form.vars.data.file,unique=False)
# for every table
for table in db.tables:
# for every uuid, delete all but the latest
items = db(db[table]).select(db[table].id,
db[table].uuid,
orderby=db[table].modified_on,
groupby=db[table].uuid)
for item in items:
db((db[table].uuid==item.uuid)&(db[table].id!=item.id)).delete()
return dict(form=form)
def export():
s = cStringIO.StringIO()
db.export_to_csv_file(s)
response.headers['Content-Type'] = 'text/csv'
return s.getvalue()
