I have a very simple app engine program. I'm following all of the JDO
instructions and have a class like this:
@PersistenceCapable
public class ExampleUser {
@PrimaryKey
@Persistent
private Long id;
@Persistent
private String name;
public ExampleUser(Long id, String name) {
this.id = id;
this.name = name;
}
@Override
public String toString() { return "["+name+":"+id+"]"; }
public Long id() { return id; }
public String name() { return name; }
}
I programmatically inserted one item for this and waiting for the
datastore statistics to exist before pulling down the config via
"create_bulkloader_config". This is the yaml property_map:
50 - kind: ExampleUser
51 connector: csv # TODO: Choose a connector here: csv, simplexml,
etc...
52 connector_options:
53 # TODO: Add connector options here--these are specific to each
connector.
54 property_map:
55 - property: __key__
56 external_name: key
57 export_transform: transform.key_id_or_name_as_string
58
59 - property: name
60 external_name: name
61 # Type: String Stats: 11 properties of this type in this
kind.
62
Here's what a sample download looks like (with the names intentionally
truncated):
1 name,key
2 Nef,1
3 clu,2
4 Guy,1
5 edg,2
Now in this example lines 2 & 3 were inserted programmatically
specifying the id as a Long. Where as lines 4 & 5 were inserted with
the bulk uploader.
When I re-upload this file I lose users on lines 4 & 5 and users on 2
& 3 are there twice. This is the view from the datastore admin panel:
id=1 Nef
id=2 clu
name=1 Nef
name=2 clu
I really want to use the Long id's as ID's in other JDO objects, but
don't think I will be able to if I can't upload with explicit Id's. Is
there any way I can modify the yaml file to insert with id= and not
name=?
