My application uses Django non-rel. I don't have access to model.

I have my bulkloader.yaml file autogenerated by appcfg.py create_bulkloader_config.

Problem is entities numeric ID's are being imported as string key names. So if I export entity with int ID of, for example, '62', it gets imported as entity with string key name of '61' which screws up Django.

Revelant bulkloader.yaml Fragment:

 property_map:
  - property: __key__
    external_name: key
    export_transform: transform.key_id_or_name_as_string

I'm trying to setup download/upload od data using bulkloader, and I want to have data as easy to understand format (like .csv) --- so using bulkloader.py --dump (...) is not a viable option since it gives me sqlite3 files that have entities contents pickled as a single row.

EDIT

I tried doing what @Nick suggested and I got an exception:

 ErrorOnTransform: Numeric keys are not supported on input at this time.

Does this mean that I have to stick to bulkloader.py (that uses that werid sqlite format) or I messed something? ;)

You've got the export_transform 'key_id_or_name_as_string', but you don't have a corresponding import transform. Try this:

property_map:
 - property: __key__
   external_name: key
   export_transform: transform.key_id_or_name_as_string
   import_transform: transform.create_foreign_key('Kind', key_is_id=True)

Where 'Kind' is the name of the kind identified in the config file.
